The view from the bridge

By Dr. S. David Webb

Looking Back with Pride

As we wrap up ARPP field operations in time for the millennium, we can share a sense of pride in our
many accomplishments. There will be scientific reports and repercussions for years to come. Certainly
the ARPP has proven that Florida's submerged resources really can support good paleontology and
archaeology. And our field teams have devised the definitive package of portable, practical devices and
methods that produce the records and specimens that the museum must hold as vouchers for the future.
We also proudly hold up our safety record 15 years and all is well.

Dr. Webb presenting appre-
ciation award to ARPP main
cany host Jack Satterwhite.

In looking back over these years I realize that the ARPP experience operates at many levels. This
column usually addressed science and safety. But there is a third, more elusive current that runs strong.
It is the shared camaraderie and sense of achievement that runs subliminally through our collective
memories. It can only be captured if at all in stories, tales, and songs. We have created our own folk
culture that lends color and texture to our commonly shared experiences, perhaps not so unlike the

Paleoindian culture we strive to see. As scientists, we write about "Hypothermia", but we also remember
it at a more personal level when we tell stories of "the big shakes" (hypothermia) and how Joe Latvis
spilled half a cup of coffee down his hand shivering from the cold following a particularly "bracing"
February dive.

Giving Thanks to Many Friends

During our last full field season this past October we held our final Open House. It was a fine Saturday
afternoon barbecue down at the Taylor County Boat Ramp. It's odd to refer to that place as the county
boat ramp, since, by the time of our gathering, Hurricane Earl had removed the two floating docks that
seemed so permanently part of the ramp. Many of us still call it Williams Fish Camp, but that was also
removed by powerful forces about a decade ago. Anyhow we had a wonderful day at the downstream
picnic ground on the Taylor county side. And it is a great tribute to our stalwart friends that they came at
all, considering how uncertain the weather was all last year, truly an El Nifio year.

ciation award fo ipen house
host J.R. Ifdi~ker.

As I sat there looking out across the full estuarine breadth of the Aucilla, I began to make a thank-you
list. I wanted to acknowledge all the people who have befriended our project. That's when it hit me how
steeply the number of friends and supporters has added up over the years (and decades). I tried grouping
the list of friends in various ways, by geography and also by chronology. I soon realized what a daunting
task I had undertaken. We have enthusiasts that have stayed with us forever, and yet we make fine new
friends every year. By the time I stood up at the barbecue I realized that my intended thank-you list
would be far too long. More appropriately, I thanked our three most vital recent supporters, namely Jack

Satterwhite, J.R. Walker and Mrs. Francis Rollins from Perry.

ciation award to ARPP
"high ground" hostess Mrs
Francis Rol s.

Since the barbecue I have continued to shake down my memory banks and add up the numbers of valued
family, friends, and supporters. And the fond memories and thank-you lists just keep unfurling. If I pick
just one person to thank explicitly for keeping this project afloat for all these 15 years it is Joe Latvis.
Another special thanks is stirred by recalling an earlier open house, certainly our most stately one, in
May, 1995. That is when Governor Lawton Chiles came, a most charming guest, and he truly enjoyed
the whole operation at the Latvis/Simpson site. We wondered later whether his visit influenced his
support, a month later, of the Florida Legislature's Special Category Budget for Heritage Preservation.
To the late Governor Chiles and our many other friends we of the ARPP thank you from the bottom of
our hearts for all of your support over these many wonderful years.


Early archaeology in Florida

By Dr. Jerald T. Milanich

Maps of important archaeological sites in the southeastern United States always include Mt. Royal on
the St. Johns River and Crystal River on the Gulf coast. Both were first excavated nearly a century or
more ago, and the extraordinary collections from each have drawn attention ever since.

The significance of these sites certainly rests in large part on the array of artifacts recovered. In addition,
the first excavations at each were carried out at a time when American archaeology was still in its
infancy, and major excavations made major impacts. Just as important is that the artifacts and data
regarding the contexts of those collections have been preserved. Fleeting archaeological fame derives
from discoveries; everlasting fame is awarded only those discoveries that are published and curated.

Mt. Royal and Crystal River both were first investigated
by Philadelphia archaeologist Clarence B. Moore, who
promptly published what he found, providing excellent .
illustrations (he also paid publication costs!). The
artifacts he collected as well as his original field notes
still exist today, providing modern researchers informed
access to the collections and their intrinsic data. At the
Huntington Free Library in the Bronx, New York, one
can read Moore's field journals. One also can visit the i
Smithsonian Institution's National Museum of the
American Indian to study his excavated collections.

Born in Philadelphia in 1852 and educated at Harvard
(B.A. 1873), Moore was never formally trained as an C.P. Moore
archaeologist. During the 1870s and 1880s he lived the 4 I'den Isl!nd incs. d l ird
life of a bon vivant, funded by family money. He A. 3
traveled widely in Central and South America and 6' V.L e (ca. A.D.3-
Europe, made an around-the-world trip, and went on an

to take up the presidency of a paper company; 20 years o ihe A wC/a Rver. (Maxmim
later at age 47 he retired to devote full time to height approximate4y r nd
archaeology. 3/4 inchev.)

Perhaps his global excursions had piqued his interest in archaeology. In 1891, then near 40, he had first
traveled up the St. Johns River, excavating shell middens. Two years later he began excavation of
mounds on the same river, an enterprise that eventually took him to hundreds of other mounds in Florida
and throughout the Southeast.

During his nearly three decades in archaeology Moore's field procedures remained much the same. Prior
to each season contacts were made with local people to locate suitable mounds for investigation and
secure permissions to excavate. When necessary, land owners were paid. A steamboat-one of which
was the Gopher-would precede Moore to the field and anchor in the river next to the mound to be
excavated. When Moore arrived from Philadelphia in January, the start of the yearly field season, he
took up residence on the boat, a crew of local laborers was hired, and excavations commenced. When
one mound was demolished the boat and crew moved to the next. Each field season continued well into
spring, sometimes into early summer, when Moore would head back to Philadelphia to analyze his
collections, write and publish reports, and prepare for the next season.

In reading Moore's field notebooks I found no great secrets or new information, though I developed
more respect for him as an archaeologist. In the field he coped with many of the same problems and
phenomena that we do today, especially bad weather and the unforeseen. His daily logs meticulously
record time, temperature, and, later, barometric pressure. A typical entry, this one from 1893 at Mt.
Royal, reads: "Wed April 12. 6 am. 650 clear, 11:30 am 820 brighter-6 p.m. 800 clear. Lay all day
[anchored] at Mt. Royal." At the onset of his second season of work (1906) at Crystal River, his January
25th entry reads, "Reached Crystal River this evening from the north and went aboard the Gopher which
lay a short distance below the town." The field season was set to start, but the next day he ran up against
the unexpected: "Spent all day at anchor near Crystal River having decided it was impossible to secure
labor for the mound on a day when the circus was in town."

Like modem archaeologists, Moore kept a tally of expenses. In 1894, for working a six-day week, each
of 12 crewmembers received $5.10.

Archaeologists have a peculiar love-hate relationship with Moore. We love him for all the information
he left us, but we hate him for digging all those sites before the modem era of archaeology brought new
field methods that would have greatly enhanced his reports. Even so, Moore did do many of the same
things we do today. He was aware of the work of other archaeologists, and he did not hesitate to call on
those colleagues and other specialists for information or analyses beyond his own abilities. He read the
literature and sought similarities between his sites and artifacts and those investigated by others, freely
sharing his information. Moore also understood principles of stratigraphy and he looked for depositional
patterns within sites.

But he was not perfect. He worked too fast and tried to do too much. His three field seasons at Crystal
River (March 11-23, 1903; January 29-February 14, 1906; and April 9-12, 1918) spanned 34 days.
Because he did not work on Sundays probably only 25 days total were spent excavating. During that
short time he and his field crews recovered the skeletal remains of at least 429 individuals and hundreds
of pottery vessels and other artifacts. Doing so much with a crew of twelve (or even one twice that size)
in so short a time would be impossible utilizing modern standards of excavation. Moore's crews must
have literally ripped things out of the ground. No grid system was used and valuable vertical and
horizontal measurements were not recorded. Nor were field drawings made.

Would we have been better off if Moore had not dug Mt. Royal, Crystal River, and other sites? Certainly
it would have been better if the sites were excavated by today's exacting standards. But the hard reality
is that had Moore not dug the sites and recorded what he did, much information would have been lost.
Vandals seeking artifacts for their mantle places would probably have destroyed many of the sites,
forever losing the data they represent.

That is why long-term projects like the ARPP are so important. They produce new information and they
assure the collected data is available forever.

PaleoAucilla Prehistory -- "Clovis Underwater '98"

By Dr. Michael K. Faught

Many of you have heard that the PaleoAucilla Prehistory Project will carry on the Aucilla River
Prehistory Project's tradition of educational and multi-disciplinary scientific research offshore, in
portions of the Aucilla that are now submerged on the continental shelf. This research has been
conducted since 1986 under a variety of project names, including Offshore Archaeology 1989, Clovis
Underwater 1992, and Clovis Underwater 1998. "Clovis Underwater" was coined for my EarthWatch
project, and I continued it in 1998 for the inaugural field research under FSU's Program in Underwater
Archaeology. But now we have a project title that will endure many seasons of research out on the
continental shelf looking for prehistoric sites submerged by Pleistocene sea level rise. The new name
focuses on the fact that we are exploring the Aucilla River offshore.

FSU's research this past summer focused on
the J&J Hunt Site, located about 3 miles
offshore, on the margins of what we think are
remnants of the Aucilla. Previous research has
shown that this location became submerged
about 6,800 radiocarbon years before present.
We also looked for additional sites at a place
we call Locus T, further offshore, but we were
turned back by poor weather before any new
sites were found. As part of FSU's commitment
to training students in both submerged
prehistoric sites and historic shipwrecks, work
was also undertaken in the St. Marks River, on
an early 19th Century vessel sunk near the
confluence of the St. Marks and the Wakulla
Rivers. Chuck Meide, Program Assistant for

will put major effort into additional mapping and survey of the areas surrounding the J&J Hunt site, and
concentrate on surveying for new sites further offshore. Chuck Meide will continue our focus on historic
shipwrecks with his Dog Island Shipwreck Survey. Students and qualified volunteers will both
participate in this cutting edge research. Those interested in participating, or supporting this in other
ways, can find more information about it on our web site (http://www.anthro.fsu.edu/research/uw/).

Golden age of the Aucilla

By William O. Gifford

During the four years that Joe Latvis and I have worked together on the Aucilla River Prehistory Project,
it has always been our habit to end our typical 16-20 hour day in the field with one final meeting.
Because Joe and I provide overnight security at the excavation site our day necessarily ends onboard the
operations support barge in the middle of the remote Aucilla swamp. The midnight isolation of this
venue provides refreshing "decompression" from the fast-paced daylight operations, while also
affording us an opportunity to discuss confidential aspects of field operations management (topics like
who compromised a particular safety protocol yesterday, who is too exhausted to safely continue diving
two dives per day tomorrow, who's worsening ear infection will require hospital treatment, who cannot
be assigned screendeck duty because they are now taking antibiotics which prohibit sun exposure, or
who requires a day offsite for psychological renewal). It was during one of these discussions that I told
Joe of my imminent marriage and the severe curtailing of my role in the project. The ever practical Joe
hit upon the idea of me writing an Aucilla River Times article about my reflections on experiences of the
last four years.

In 1994, I had been working as a volunteer for the Palm Beach County Reef Research Team and
teaching SCUBA diving at DeLeon Springs. When I heard about a Nautical Archaeology Society class
and subsequent survey of the spring by Gulf Archaeological Research Institute, I thought that this would
be a good opportunity for former SCUBA students and interested local divers to expand upon their skills
and to learn more about the history of the spring area. Led by Dr. Robin Denson, we mapped and
recorded data over 26% of the spring area in nine days. It was my first chance to work as a divemaster in
this type of situation, and I have to admit I enjoyed the challenge enormously.

At the behest of Robin, who in a short period of time had become a close friend, several of us applied to
and were accepted with the ARPP. When I received the dive plan, I was truly impressed with the scope
of this document. It seemed to cover all contingencies, and gave one an idea of what would be
encountered in the field. Of course this was not entirely the case, but as the project evolved so did the
dive plan, and over the years it has expanded to cover new and previously unforeseen problems. I know
that over time everyone has heard Joe and me refer to it ad nauseum, but the answer to most of your

safety and operational questions are contained in it (see "ARPP: scientific diving to national standards").

The backbone of the ARPP over the nine field seasons that I have been involved was the volunteers.
With funding provided by the State of Florida through the Department of State and the Bureau of
Historic Preservation, the ARPP was able to provide for the care and feeding of volunteers who were
eagerly applying in ever-greater numbers from throughout Florida, the nation, and the world. Our
increased ability to accommodate more workers not only increased research output but brought in divers
and screen deck personnel from widely divergent backgrounds. The trio that eventually became known
as the 'Volusians' (from Volusia County) was such a group.

The Volusians consisted of Mike Nolan, a broker and grower of foliage greens, Steve Glover, a retired
ad exec and myself. Mike brought with him the common sense of a farmer and the skills needed to keep
practically any piece of machinery running. Steve came with a passion for learning and an understanding
of the bureaucratic maze that envelopes funding such as ours. His skill as a musician provided relief
from the tension encountered in the stressful environment in which we worked. One of my fondest
memories is the night the Volusians had stayed at the Nutall Rise base camp to catch up on some repairs
that needed to be done while everyone else had gone out to dinner. After finishing our work and dinner
we played some music and relaxed. Upon the return of the rest of the crew, Steve and I found ourselves
accompanied by Dr. Webb in an a cappella version of "Ain't Necessarily So" that the residents of Nutall
Rise will never forget. The mere mention of this song probably puts their teeth on edge. Steve and Mike
recognized the growing need for additional divemasters in the organization and enrolled in a class with
me as their instructor. They both excelled in the class and became even more valuable members of the
ARPP as fully certified divemasters.

Another noteworthy group of volunteers was the students attracted to the project from FSU. FSU has an
excellent dive program and their addition helped fill out our operational assignment roles. Along with
the divers from FSU came many excellent screen deck personnel as well.

Screen deck people are a breed unto themselves. As divers, we don't understand them, but that doesn't
mean they go unappreciated. Led by long time participants such as legendary dredge guru Ed Green,
Mary Hudson and Dawn Pinder, the addition of Alyssa Mc Manus, Hank Kratt, Tanya Peres, Tammy
Montes and Joann Suggs gave us a crew that was able to determine when an artifact, faunal or botanical
remain of consequence came up on the screen. Ed knows the different strata that divers excavate into so
well that he can tell what layer you are in by the color of the dredge discharge. These people work in the
blazing sun and freezing cold, facing dangers ranging from snake attacks to dehydration. They are a
primary component of every successful ARPP field operation. With the departure of Ed Green, we were
lucky enough to have John Eveland arrive on the scene. A gentleman of unflagging good humor, John
has always been there when we needed him. Whether single-handedly repairing dredges in the offseason
or lobbying for funding in Tallahassee, he has always been glad to help in any capacity.

The scientific group was led by Co-Chief scientists Dr. S. David Webb and Dr. Jerald Milanich. Dr.
Webb, a paleontologist, has been cofounder (with Jim Dunbar) and director of the project since the

beginning in 1983. Dr. Milanich joined us later when the need for a degree anthropologist became
apparent. They have lent guidance and support to the various field scientific directors at the many
diverse sites we have excavated on the Aucilla River. The field scientific directors, with the exception of
Dr. Michael Faught, have been graduate students from the University of Florida. Their ranks since 1995
include Brinnen Carter, Andy Hemmings, Mark Muniz and Matt Mihlbachler.

Dr. Faught came to us in the fall of 1994 from the University of Arizona where he had studied under Dr.
Vance Haynes, one of the leaders in the study of the peopling of the Americas. This was actually his
second coming, as he had trained with the ARPP in 1987 and worked the Florida offshore in the late
80's. His arrival at the Page /Ladson site brought a wave of enthusiasm that inflamed us all for the
arduous task that lay ahead. Armed with a new, red-hot Ph.D. he added spark to a weary group of divers.
On the flight from Arizona Michael came up with a new and innovative idea for digging through the
nearly 20 feet of extremely hard packed clay on the bottom of the river. After a series of less-than-
successful field trials, redesigns, and modifications to Michael's PVC brainstorm, it was ignominiously
dubbed "the Faught-o-lator". In fact he swears that he could still make it work if we were just to give it
back to him. Michael has been a good friend to me and the project over the years and now heads the
Program in Underwater Archaeology at FSU. With the end of the ARPP looming he will carry our work
to the natural extension of offshore exploration (see "PaleoAucilla Prehistory...").

Brinnen Carter was field scientific director of the Bolen component at the Page/Ladson site. A Ph.D.
candidate at UF he had worked on the project as an undergrad with Dr. Denson. Brinnen has taught at
FSU as an adjunct professor and now works for SEAC in Tallahassee.

Andy Hemmings came to us from the University of Arizona when Dr. Faught came here to run offshore
excavations in the late 80's and early 90's. He is finishing his graduate work at UF. Andy has headed
our excavations at Sloth Hole, a site on the west run of the Aucilla River. Sloth Hole has been a treasure
trove of artifacts (see "Sloth Hole site update"). They include points, knives, tools, bone pins, ivory
foreshafts, fishhooks and extinct megafaunal remains. Clearly it will take years to assimilate all the data
collected here.

Mark Muniz now has his masters degree from UF and is continuing his studies at the University of
Colorado. His area of study while he was with us was the section of the Aucilla known as Little River.
Completely enclosed by the Ladson property, it provided great amounts of megafaunal remains in its
one-mile run before going underground. Mark was one of our best divers, and some of the best dives I
had were with him. During a filming session at Sloth Hole, he and Joe and I made a four-hour dive that
netted us 15 minutes of film. Filming under these conditions is difficult at best, but without a diver of
Mark's caliber it would have been impossible to get the results that we wanted. The ability to remain
motionless in such close quarters and still get good shots is indeed a special talent.

Matt Mihlbachler came to us by way of Southern Illinois University. While there he was a student of
renowned paleobotanist Dr. Lee Newsom. His work with her gave us a great deal of help in studying the
mastodon digesta found at both the Page/Ladson and Latvis/Simpson sites. I have worked with him

extensively on this and have learned quite a bit from him. Matt is now a zoology graduate student at UF,
and when you see the fire in his eyes while discussing his field you'll understand why we all think of
him as an asset to the project.

Besides the roster participants there are many people who have helped us. David Janet and the late
Wilmer Bassett provided us with guidance through the intricacies and pitfalls inherent in politics and
legislative funding. Dr. Hoyt Home, a true southern gentleman, volunteered as the project's field
physician and was kind enough to invite us into his home for an occasional home cooked meal. J.R.
Walker, whose local Aucilla River store was an oasis in a remote area of the world, provided us with a
place to establish a base camp when our former camping and equipment storage areas became
inaccessible. When the cabin J.R. donated for our use in 1997 became unavailable the following year up
sprang another good friend, Jack Satterwhite, who offered us yet another campsite through the last two
field seasons in 1998. Martha Wiggins, owner of Yarbrough Tires of Perry donated tires for our boat
trailers that were of such an obscure size we probably never would have found them anywhere else. Jim
Hunt of Zaney Foods, a longtime supporter, fed us when we had no cooking facilities. Buster Hancock
donated the six inch dredge and Snooper light that have served us so well. Bubber Bailey pledged CSX
railroad funds for equipment and ARPP scholarship needs. Tom Vereen generously donated his
beautiful blue 20-foot aluminum Duracraft boat to the project just when we needed it most.

Legislative support came from then-representative Alan Boyd, Janegale Boyd, Marjorie Turnbull, and
then-representative Carl Littlefield. Marjorie was our first legislator who dove on the site. Then last
year, Carl Littlefield became so interested that he dove with us for a week (see "State Rep. Carl
Littlefield dives with ARPP"). Senatorial support was generously provided by Sen. Pat Thomas, Charles
Bronson, and then-senator Patricia Harris (now Secretary of State). Then-governor Lawton Chiles
demonstrated executive concurrence by signing the budgets that contained Division of Historical
Resources funding for the ARPP.

Of all the people I've mentioned here, the two most important in my eyes have been Dr. Webb and Joe
Latvis. With the project since its inception, they have been the driving force behind everything that we
have accomplished. Dave has maintained control of the science, yet given everyone the chance to deal in
their own field of expertise. It was his international reputation that gave us respect in the scientific
community long enough to have our say. When it came time to fire up a student, he was there with the
torch. Working with him in the museum has been one of the true pleasures of my life. Joe Latvis has
become one my best 'comrades-in-arms' as successive weeks in the field season became months of
cumulative deprivation and fatigue. His dive plan was one of the major draws for me with this project.
We are both very safety oriented, and his engineering background gave him the vision to make this a
world class project. Working so closely together we have become almost telepathic in our
communications. All divers work in a world of silence and use sign language to speak, but we have been
of such a similar mindset that it has gone beyond that with us.

There will be many of the participants on this project that have not been mentioned here: Rhonda
Brewer, Thadra Palmer and Melanie Damour, divers from FSU who gave their all in a male dominated

field and never complained when I asked them to dive a double. Dr. Joan Herrera, with whom I made
my first dive on the project. Jody Barker, a welder from Orlando who rebuilt our boat trailers from the
ground up. The list goes on, but if I missed you it was not because I didn't appreciate all of your
contributions. I am limited here by constraints of time and space. My only suggestion at this point is that
you contact my editor, Joe Latvis. It was surely his fault.

Editor's Note: mea culpa.


Endgame...and beyond...

By Joseph M. Latvis

After a spectacular fifteen year run the Aucilla River Prehistory Project is beginning its endgame in
1999. This does not mean that the great archaeological, paleontological, paleoenvironmental, geological
and hydrologic questions of the age have been resolved. To the contrary, the ARPP has explored some
of the many significant archaeological sites currently expanding the envelope of human antiquity in the
New World. The time and tide of this large scale, longterm and far ranging cooperative endeavor have
carried us all to a pregnant pause, and a new point of departure.

For instance, this is the final issue of the Aucilla River Times. (That is why no subscription request form
appears on the back cover.) However the ARPP website (which contains all recent issues of the
newsmagazine, as well as a "virtual museum" of fossils and artifacts) will remain active at http://www.
flmnh.ufl.edu/natsci/vertpaleo/arpp.htm. Kudos belong to all the authors, photographers and production
volunteers throughout the years whose manifest talent made the yearly issues so informative and well

The final ARPP field season will be conducted May 4th through 31st 1999. However, because all field
roster positions have been filled by returning veterans, no "Call for Volunteers" or "Volunteer
Application Form" appears at the end of the "Life in the Field" section of this magazine. Field crew
volunteers have been a renewable resource of skill and enthusiasm from the very first field season in
November 1983. (All volunteers since 1995 can expect to receive a "Volunteer Appreciation Package"
as the ARPP's parting acknowledgment of their outstanding avocational contribution.) Opportunities for
students and volunteers to participate in similar underwater archaeological research programs remain
available via the ARPP's sister project sponsored by Florida State University's Program in Underwater
Archaeology. Information regarding the PaleoAucilla Prehistory Project's 1999 summer field season
(June 28th through August 6th) can be accessed at http://www.anthro.fsu.edu/research/uw/.

Once the May '99 ARPP field season is completed the fifteen yearlong windfall of Aucilla River fossils.
artifacts. sediments and paleoenvironmental samples accessioned into the FLMNH collections will

cease. However these field specimens will remain available for research in perpetuity, and interpretive
exhibits for public display and education will continue to be assembled for years to come. Photo and
video documentation accumulated throughout the seasons of field operations will incorporate the
moment of discovery into these exhibits also. The definitive written document of the project's research,
currently being assembled into First Floridians and Last Mastodons will live on in the literature of
scientific discourse.

As I navigate my own personal passage from the Aucilla River Prehistory Project to the PaleoAucilla
Prehistory Project I celebrate four relationships (one institutional and three personal) that are my
considerable inheritance from this tumultuous Florida experience in underwater archaeology. In 1981,
after eight years and eight overseas engineering assignments, I established my newly chosen stateside
residence in Florida, where I continued lifelong avocational interests in fossils and artifacts. Having
discovered the Florida State Museum (now FLMNH) soon thereafter, I volunteered for the first (1982)
Thomas Farm fossil dig open to amateurs. What an enlightened institution, to be so productively
harnessing the latent energy and talent of volunteers in such worthy causes. The Museum has also been
the support platform from which fifteen years of ARPP field expeditions were planned and launched, as
well as the repository for the tens of thousands of fossils and artifacts that were recovered from the

Having met Dr. S. David Webb at Thomas Farm (and having made no secret of my passion for
combining paleontology and archaeology with SCUBA diving) I was delighted at his subsequent
invitation to participate in the newly constituted "Half-Mile Rise Project" on the Aucilla River in 1983.
What an adventure that was, as I grew to appreciate the scientific value represented by the sedimentary
context in which fossils and artifacts are discovered. Although there was no prescient grandiose design
for this project to span any more than one season, by 1987 I found myself once again back at Half-Mile
Rise, diving alongside a graduate student from the University of Arizona who proposed looking for
archaeological sites offshore in Apalachee Bay. After five subsequent field seasons out on the
submerged continental shelf with Dr. Michael Faught, I remain forever indebted to him for planting the
seed back in 1987 that the relict karst river channels offshore of northwest Florida are indeed very
promising places to explore for intact Pleistocene sediments that survived the marine transgression.

By 1995 the ARPP was growing into its destiny, conducting cutting edge research that attracted dozens
of student and avocational adventurers each field season. Diving instructor Bill Gifford came to the
project with a no-nonsense attitude toward field operations safety and efficiency, as well as a
commitment to helping each diver grow to his or her fullest potential. (Bill was also the only staff
member willing to tolerate longterm close quarters confinement and primitive camping conditions
onboard the operations vessels with me, as we provided overnight security at the site camp every
subsequent field season.) I wouldn't have missed even one of those hundreds of hour-long, midnight,
flashlight, white knuckle, shoot the rapids, bump in the night canoe passages we made between base
camp and site camp.

And finally, it has been my distinct privilege and pleasure to have been associated with so celebrated a
scientist, educator and humanitarian as Dr. Webb for these past fifteen years. Never have I more

thoroughly enjoyed working so intensely on so many creative, diverse and simultaneous assignments
with such demanding deadlines for such a marathon endeavor. Thank you for the opportunity and the
friendship of a lifetime.


Latvis/Simpson site update

By Matthew C. Mihlbachler

The Latvis/Simpson site (8Jel500) richly records a time that predates human occupation in Florida. It is
filled with a detailed record of a biotic community that dates from well before the last glacial advance at
the end of the Pleistocene epoch. Like Page/Ladson and many other locales along the Aucilla river,
Latvis/Simpson is a sinkhole, once filled in by sediment that is now partially scoured out by the current
river channel. A cross section of intact sediments remains on the west bank, cut by the river channel to
form a sloping wall of clays and peats recording the last 32,000 years of environmental conditions in
North Florida. In 1995, the ARPP dug a giant stairway down the west bank, from the youngest strata to
the oldest, where we sampled sediments of various ages, filling in chronological gaps and environmental
information for a much longer time period than previously known from the other, much younger
Paleoindian sites we have excavated.

Our final season at the Latvis/Simpson site ended this past summer in late May 1998 after two and one
half weeks of extra-hard work by the entire field crew. This time we concentrated on the bottom of the
sinkhole, excavating a large deposit of once deeply buried, finely chopped plant remains lining the
bottom of the sinkhole. Although protected for centuries by 10 meters of overburden, it is now exposed
to the erosional forces of the Aucilla current, and is slowly being eaten away by this current. From dung
samples collected in 1995, we knew that this unique plant layer consisted mostly of the dung remains of
mastodons that had used the Latvis/Simpson sinkhole as a drinking hole and wallow 32,000 years ago.
At that time, water levels were much lower, and the sinkhole was probably an isolated pool of water.
The main objective of our excavations was to collect a series of mastodon digesta samples for
reconstructing the diet of these extinct megaherbivores, and to compare them to the much younger
mastodon digesta samples from Page/Ladson. Our efforts were fruitful and we achieved ample samples
of digesta. Bill Gifford and I are painstakingly sorting through these samples (see "Wonderful Life in a
petri dish"), while Lee Newsom, a botanist and anthropologist from Southern Illinois University in
Carbondale, is helping us identify the plant fragments. Our preliminary view of these samples indicates
that the mainstay of the mastodon diet in this region was the twigs and leaves of cypress and buttonbush.
A healthy array of other species was present in the diet as well, including plums, grapes, elderberries,

creeping cucumber and gourds.

As you can imagine from the size of mastodons and the large amount of plant materials that they
consumed, the rate of deposition of the dung layer was quite rapid. The dung layer turned out to be about
60 cm deep and probably accounted for just a few years of mastodon activity at this sinkhole. The rapid
rate of deposition caused fish, turtles and mammals that died in the sinkhole to be buried and beautifully
preserved. In most cases the bones were not even fossilized but retained their original calcium phosphate
and collagen matrix. As we uncovered these plant and animal remains, we realized that this site
contained a singular snapshot in time of an animal community specifically adapted to cool and damp
forest conditions dominated by mastodons, ground sloths, tapirs, deer, muskrats and beavers.

Our most exciting osteological find was a partial skeleton of a young female mastodon lying in the
bottom of the sinkhole, buried in the digesta. The recovered material includes a pair of tusks, a complete
mandible with a complete set of dentition, a pair of scapulae, a humerus, a tibia, numerous vertebrae,
foot bones and ribs. Unfortunately, most of the skeleton appears to have eroded away long ago, but
enough was recovered to really understand the age and health status of this animal. Paleontologists are
well aware that fossil proboscideans are "filled with biology". The slow growth rates and long life spans
of proboscideans allow the skeletal elements, especially the tusks, to accumulate a wealth of information
about the lives of these animals and the environments they lived in. Various aspects of the Latvis/
Simpson mastodon are under study by numerous scientists for purposes of reconstructing the lives of
Florida mastodons and the environments in which they lived. As part of a larger study of Florida
mastodons and mammoths, scientists from the University of California at Santa Cruz sampled the
enamel of the mastodon's molars to determine the oxygen, carbon and strontium isotope signatures.
Isotopic signatures provide information about diet, migration patterns and annual temperature changes in
the environments that the proboscideans occupied.

At the Florida Museum of Natural History we are in the process of interpreting and reconstructing the
life of the Latvis/Simpson mastodon. The first clue about its life came when we noticed that most of the
bones of this mastodon are unusually porous, and a few of the ribs have pathological growths indicating
that this animal may have died from some yet unidentified disease. I looked into the life history of this
mastodon by analyzing the growth rings in the tusks. Tusks of proboscideans continually grow
throughout life and preserve a record of each individual's life history and its environment. Like growth
rings of a tree, annually alternating dark and light bands are visible when the tusk is sliced in cross
section. These growth lines record the age of the individual, the alternation of the seasons, and the
growth rate and health status of the mastodon throughout its life history. With the help of a saw from the
Department of Agricultural Engineering and a couple of willing hands we bravely sectioned one of the
Latvis/Simpson mastodon tusks in the hope of retrieving this information. As it turns out, I counted 12-
13 alternating light and dark bands (summer and winter bands), and if we add the missing two years that
this animal would have had its deciduous "baby" tusks we can calculate that our mastodon was 14 to 15
years of age when it died. Although not fully grown, this mastodon was just past the age when living
elephants give birth to their first offspring. Ironically, a few small, very porous, incompletely formed
bones were found associated with the mastodon material that appear to be from a late stage fetus. It is
likely that our unfortunate young mastodon would have been a new mother if it had not died at such a

young age.


Sloth Hole site update

By C. Andrew Hemmings

Two field seasons at Sloth Hole (8JE121) in 1998 gave us our most detailed look at the site yet. If you
can wade through the detailed description below you will be rewarded with news of our amazing finds
from 1998. Major excavation activities are nearing completion in the areas containing intact strata. Intact
stratified sediments have been excavated well into Pleistocene deposits everywhere we have
encountered them. Exposed surface material remains in some portions of the site but we have
aggressively collected that material as well. Additional terrestrial and bathymetric mapping will be
combinedwith some final surveying this summer.

In 1998 one of our major goals was to construct a continuous stratigraphic column of stepped
Pleistocene/Holocene sediments. From the greater than 41,980 year old (Beta # 83379) compacted slick
peat in the bottom we traced the sediment 10ft vertically to the 34,760 +/-1600 year old in situ palm
stump (Beta #95342). We wanted to connect this sequence with the terminal Pleistocene (12,300 year
old) sediments encountered to the east. The eastern sediments contained a detailed but discontinuous
sequence of terminal Pleistocene to modern material.


under construction

We were able to track the strata from 34,760 to 12,300 radiocarbon years ago. This period is contained
in a homogeneous highly compacted layer of gray silt/clay, fine white sand, limestone pebbles, wood
and animal bones nearly 160cm thick. 60cm above the 34,000 year old layer we submitted wood that
returned a radiocarbon date of 28,470+/-170 years old (Beta #119349). This lower portion of the
sequence seems to preserve continuous slow deposition of material.

The 12,300 +/-50 year old date on wood (Beta #95341) represents the top of the 160cm stepped
sediment sequence discussed so far. However, this date is at the bottom of a 183cm vertical column of
continuous terminal Pleistocene fine silts and clays. Seemingly these represent quiet water backfilling of
a pond environment. Numerous flaked stone artifacts were found above this layer but unfortunately no
tools were recovered. We hope to excavate more of this material this summer.

The 1998 seasons represent the end of concentrated generation of field data from Sloth Hole.
Incremental growth of the data set is proceeding by contact with river divers who have collected
material from Sloth Hole. I am very interested in talking with anyone who has material or data about
Sloth Hole. If you have artifacts or fossils from the lower West Run of the Aucilla please contact me at
the Florida Museum of Natural History.

Outreach with numerous collectors has yielded casts, images and detailed information regarding great
quantities of worked ivory tools, six Clovis points and numerous other bone, stone and ivory tools.

The most dramatic find we have documented is a weakly stained fluted Clovis point (see Figure 1) found
by Kurt Cox. The morphology of this Clovis point is distinct from the one in the Ohmes collection on
the cover of this issue. Whether the different shapes are separated chronologically or simply represent
different contemporaneous knappers' work is virtually impossible to say.

The density of the Clovis occupation at Sloth Hole is further demonstrated by the large amount of
worked ivory recovered (2 complete points and 58 fragments, some of which are nearly complete). In
the earlier work of the ARPP we had recovered only four slivers of ivory tools, including the 8.3cm
piece described in the last Aucilla River Times. 1998 was our bonanza year. 15 pieces of ivory were
found across the site. Five pieces were refitted and glued together. This unusually slender ivory point
(see Figure 2) is 33.3cm long. The hafting end and a portion of the shaft are missing, so it probably was
40cm when complete. The 33.3cm section is the longest piece in the FLMNH collections and is
noticably longer than worked bone and ivory shafts reported anywhere else in North America. The
slender diameter and great length seem to indicate that this is indeed a point rather than a foreshaft.

Several stone projectile points were found in various contexts last year. Several lanceolate Paleoindian
point fragments were located, including what appears to be the midsection of a resharpened Simpson
Sunfish. An unusual Clovis point with a unifacially resharpened impact fracture was found and loaned

by Kurt Cox.

Several individual finds deserve mention while discussing projectile points found last year. Matt
Mihlbachler found an 8cm unbevelled Bolen. Overall we found seven more Bolen points roughly all in
the same area as the Aucilla Adzes. Susan Kane found her first point, a heavily resharpened Culbreath-
like comer notched point. Melanie Damour also found her first point, an expedient arrow point made on
an old flake. This point is rather unusual and not attributable to any type. However, it superficially
resembles a Kirk comer notched variety.

Last year we reported the recovery of seven Aucilla Adzes in our earlier work. Five more Aucilla Adzes
were recovered in 1998. Additionally, data on five more from Sloth Hole was generated from specimens
in the Ohmes collection. This brings our total to 17. This density in one site is somewhat of a surprise to
us. Certainly the case for an Early Archaic Bolen age wood working activity area is bolstered by the
dramatic increase in sample size from one portion of the site.

It turns out that the Aucilla Adze is not as rare as reported last year. It now seems there are indeed
hundreds of them known. While not as common as Bolen points they are a good cultural and temporal
indicator of Early Archaic Bolen peoples.

Other stone tool discoveries included: bifacial and unifacial scraping and chopping tools; formal
unifacial graver spurs; flaked stone cores and many other tool types.

A wide variety of bone and antler tools dominated the surface collections. Several hundred bone pin or
point fragments and nearly a hundred complete bone tools were found. Some of the shorter bipointed
bone tools appear to be gorge fishhooks.

Numerous bone fishhooks were recovered this year. The most interesting form is a barbed type (see
Figure 3). No single piece barbed fishhooks have been reported in the Florida literature. The barbed
hook is made from the proximal end of a left deer radius. One complete example and two broken barbs
were located, all made on left radii. This deer radius barbed hook seems to be the first true
archaeological "type" encountered, possibly in the whole of the Southeast. Since our initial discoveries
we have learned that more than a dozen of this type of hook are known in private collections. An article
describing this type of hook is being written with Ryan and Harley Means who have found several of
these at another location.

The most surprising artifact yet collected at Sloth Hole was discovered in the museum collection amid
unsorted faunal remains. Amy Schwarzer found a lynx mandible with an incised spiral pattern repeated
three times on each side (see Figure 4). It was recovered slightly outside of Sloth Hole proper in an area
containing most of the pottery we have found. The mandible is most similar to material reported from
Tick Island and could be older than 6000 years BP. While probably newer than the Paleoindian materials
we normally focus on it is a great contribution to distributional data for this type of bone working.

While trying to explain the potential benefits of sorting faunal materials to Brian Beatty he found a piece
of turtle carapace with the same geometric pattern carved on it.

The faunal finds were as spectacular as the artifact finds last year. No new extinct animals were added to
our faunal list, but more remains of mastodon, mammoth, camel, tapir, horse, sloth (Megalonyx), and
muskrat (Ondatra locally extinct) were found.

Our best in situ material was from two mastodon (Mammut americanum) skeletons that we have been
following across the site since 1996. Prior to 1998 we had recovered most of the limbs of a juvenile
mastodon and good portions of the skull of a very old mastodon. In 1998 we found both astragali and a
calcaneum of the juvenile and the left calcaneum and right astragalus of the old fellow embedded in the
28,470 +/-170 RCYBP sediment adhering to the proximal end of a 7.5 foot mastodon tusk.

The large unstained calcaneum dated to 12,180 +/-60 RCYBP (Beta # 119350). This indicates that a
12,000 year old mastodon died and was deposited in 28,000 year old sediments on the edge of a pond.
Because both mastodons' remains were found on a ten foot terrace, and in this case unstained and in
situ, we feel confident they are nearly in the position in which they died at the end of the Pleistocene.

As Sloth Hole fieldwork comes to an end it is clear the remains of a very strong Clovis presence, and
Bolen presence, that we have documented will make broad contributions to both Florida's archaeology
as well as the continent wide investigations of Paleoindian adaptation(s) and migration. As the museum
research now hits full stride the significance of what we have been doing in the field all these years
becomes readily apparent, sometimes on a daily basis.


Fossil Hole site update

By C. Andrew Hemmings

In 1997 the ARPP briefly revisited an inundated quarry site at the southern tip of Ward Island called
Fossil Hole 8JE1497, which we had documented in 1994. Our goals then were to see how much
diagnostic artifactual material remained in the surface collection, collect additional raw material
samples, and document the site perimeters.

While surface collecting we
encountered numerous post cranial
pieces of Holmesina, the extinct
armadillo. This is a somewhat unusual
late Pleistocene genus to recover in
the Aucilla River. The formerly
exposed knappable bedrock chert
outcrop had been buried by recent
storm action, which prevented us from
collecting any samples.

As part of the 1998 summer field
season we decided to spend three days
on this site. Our goals were to
thoroughly surface collect the site
looking for clusters that might
represent camping areas and to do
some limited excavation seeking
stratigraphically intact sediments in
the dense lithic scatter.

Unit 1 produced an astonishing amount of flaked stone material (N=37,218 flakes and 28 cores). Three



natural stratigraphic levels were delineated during excavation. The strata and separate artifact counts are
presented in Table 1.

Several unusual features bear reporting. Only one flake was bifacially worked, and even this example
was not beyond very early bifacial reduction when it broke. The five largest cores weighed between 50
and 86 pounds each. Flake counts from Levels 2 and 3 are sure to go up slightly when sediment samples
are processed in the future. Virtually every conceivable stage of reduction flake is present in this one-
meter square. Cortical primary flakes, primary flakes, secondary flakes, shatter, bifacial thinning flakes,
broken flakes, flake fragments, pressure flakes and core trimming flakes are all present. Very little
bipolar flaking seems to have occurred in this sample.

they have been undisturbed for a minimum of
8500 years. This would indicate an Early Archaic cultural affiliation at the youngest.

A terminal Pleistocene date is possible for the cultural material encountered in Level 2 and below. This
is based on the only identifiable large mammal remains being Tapir, which is of course locally extinct.

Two bone pin fragments were recovered in Level 2 as well. It is tempting to tentatively assign a
Paleoindian or Early Archaic designation to these items. If it turns out they are Paleoindian in age that
helps establish a very early date for the use of these items in the prehistoric tool kit.

Our enthusiasm regarding the paleoenvironmental data noted so far should be held in check until the
context of deposition for the Fossil Hole sedimentary sequence is more fully understood. The
microhabitats of the assorted gastropods may prove to be our most fruitful line of inquiry to pursue
based on what we now know.


Wakulla Springs Karst Plain Symposium

By Joseph M. Latvis

On October 9,1998 the Florida Geological Survey in conjunction with several other agencies sponsored
a technical symposium at the Florida State University Turnbull Conference Center. Approximately forty
speakers presented their talks in two concurrent sessions. Florida State Representative Janegale Boyd
(House District 10) provided Keynote introductory remarks. Topics of particular interest to
archaeologists and paleontologists conducting research in the Karst Plain region (which encompasses the
study area of the Aucilla River Prehistory Project) included:

During the past decade the
Aucilla River Prehistory
Project (ARPP) has NASA Shuttle photo of Wakulla Springs
intensively explored the
middle reaches of the Aucilla Karst Plain
River in search of relatively
thick, continuous sections of late Pleistocene sediments. Teams of paleontologists and archaeologists
have successfully excavated more than a dozen such sections using SCUBA, dredges and underwater
lights. The various sections studied by the ARPP range from about three to more than five meters thick
and represent nearly continuous deposition of fine-grained, highly-organic plastic sediments, including
peats, clays, silts and fine sands. Most of these sections lie immediately adjacent to relatively deep holes
in the uneven bottom profile of the river. Evidently these sediment packets in the Aucilla River represent
sinkhole fillings in the Suwannee Limestone, now partially exposed by the river.

In the course of its excavations, the ARPP has acquired more than 90 radiocarbon dates on river-bottom
sections from the middle reaches of the Aucilla River. We anticipated that the dates would represent the
last deglacial hemicycle, driven by a rising piezometric surface geared to the latest glacial sealevel rise.
For a majority of dated sections these expectations were fulfilled. For example at the Page/Ladson site
sediments record fine details of back-filling history between 15,000 and 9,000 radiocarbon years
(Oxygen Isotope Stage 2). Quite unexpectedly, however, nearly 40 percent of the sediment packets
sampled and dated by the ARPP represent a previous interval of sinkhole filling with dates between
about 28,000 and 34,000 radiocarbon years before present. This earlier cycle of sinkhole filling
correlates with the next highest oxygen isotopic peaks (Stage 3) (before the latest Pleistocene) in the
Greenland Ice Core record. The abundance of such sediments in the Aucilla River, despite being
overprinted by a later cycle, suggests that they played an important role in regional karst history.


Patterns of sediment deposition in the middle Aucilla


By Dr. S. David Webb

After investing considerable time and energy in locating late Pleistocene sedi- ment deposits in the
Middle Aucilla River, the ARPP might be expected to have discerned some patterns of how such
sediments accumulated and how one might locate further bodies of similar nature. Besides recording the
kinds of sediments and the geometry of their deposition, the ARPP also has a substantial inventory of
their ages based on about 90 carbon-dated samples from more than a dozen sites in the river bottom.

The ancient sediments of the Aucilla River consist of two unequal sets of very different genetic origin.
The prevailing "bedrock" is the Suwannee Limestone of Oligocene age, about 30 million years old.
Along the river bottom this limestone is often exposed as shallow hard bottom. But it alternates with
deeper, subcircular exposures of highly organic peats, clays, silts and fine sands of late Pleistocene age,
less than a million years old. ARPP's work shows clearly that these sediments represent sinkhole

The substantial number of carbon dates
obtained by the ARPP from late Pleistocene deposits in the Aucilla River provides a general schedule of
sinkhole filling sediments in the Wakulla Springs Karst Plain. The essential data are summarized in the
accompanying figure. The dates are grouped by river segments, the Half-Mile Rise, farthest inland, and
West Run, nearest the mouth. A major cluster of dates in the last deglacial hemicycle, from about 15,000
to about 9,000 radiocarbon years before present is to be expected. The older clusters, however, are
somewhat surprising. The explanation for an older cluster of carbon dates between 24,000 and 32,000
years, best shown in Little River, is that this represents the penultimate glacial rise. The oldest cluster of
dates between 36,000 and more than 42,000 corresponds to still another meltdown. It is interesting to
note that as one moves down river the accumulations of late Pleistocene back-filled sediments appear to
become more equally recorded. In Half-Mile Rise, farther inland, there is no record, insofar as we know,
of older interglacial or interstadial records.

Editor's Note: In October 1998, Floridians celebrated Earth Day along with many others in the United States
and Canada. Governor Lawton Chiles issued a proclamation underlining the importance of Earth Day and of
appreciating geology. One of the events in recognition of Earth Day in Florida was the Wakulla Springs Karst
Plain Symposium held at the Turnbull Conference Center on the campus of Florida State University (see
"Wakulla Springs Karst Plain Symposium ). This article is a synopsis of the paper presented on behalf of the
ARPP by project director S. David Webb. A longer version is in press in the symposium volume to be issued by
the Florida Geological Survey, edited by Dr. Walt Schmidt, Survey Director.


Natural site formation processes

By Krister Efverstrim

First of all I would like to thank Joseph Latvis, Bill Gifford and David Webb for
giving me the opportunity to participate in the ARPP. It has been, and will be, a
big adventure for me to work with a culture that I had little knowledge about
before this summer's Clovis Underwater '98 excavation in the Gulf of Mexico
and the fall ARPP expedition at Sloth Hole on the Aucilla River. I also would
like to thank Andy Hemmings for his time and trust with me concerning the
scientific work. I hope that my analysis will contribute to a better understanding
of the Paleoindian/Early Archaic cultures.

The climatic changes that have occurred in the northern temperate zone over the course of the past
20,000 years have been nothing short of dramatic. The climatic shift from a regime of arctic severity to
one of relative warmth began around 15,000 BP. It led to the virtual disappearance of the continental ice
sheets and to the replacement of barren tundra by mixed woodland over large areas of Europe and North
America. A combination of climatic and vegetational changes exerted a major influence on a range of
other landscape processes including fluvial activity, weathering rates and pedogenesis. Landscape,
people and climate are three variables which are inextricably linked, and an understanding of the course
of environmental change requires analysis not only of the elements themselves, but also of the way in
which each influences the other.

In the commentary section of Anderson and Sassaman's The Paleoindian and Early Archaic Southeast,
Henry T. Wright celebrates the great variety of Paleoindian/Early Archaic stone artifacts and the
importance of understanding and interpreting this variety. He also argues for the importance of knowing
the local environment in the area of a site at the time of the site's use. Between these two big issues I
would interpose the importance of understanding the site-formation process because of its influence on
cultural and environmental development. Archaeological sites are three dimensional mosaics consisting
of natural sediments, vegetation, modem artifacts and settlement and archaeological remains. In order to
understand how settlements functioned in regional systems, one must try to reconstruct changes in the
landscape. Much of the archaeological variability within and between regions is a consequence, not only
of past human behavior, but also of differences in the local environmental processes that form an
archaeological site. Joel Gunn proposes on page 420 in the same 1996 volume cited above, that sites
need to be seen in the context of the environment at the time of occupation, not in broad regional
community syntheses and that Paleoindian/Early Archaic transition can be elaborated to include that
the site-specific conditions are a part of the global ecological context".

Understanding site-formation processes is, I believe, one important key to unravelling archaeological
questions, especially for inundated archaeological sites like Sloth Hole, because of the depositional

complexity. Because the site is producing so much cultural evidence, it is particularly important that we
understand its environmental formation processes. In addressing site-level environmental processes, one
asks three basic questions:

1. What noncultural processes contributed materials, as ecofacts, to the deposits?
2. What noncultural processes modified the deposits?
3. How did noncultural processes affect behaviour at a settlement?

The focus of my research will be to describe the process of site formation at Sloth Hole. A study of non-
cultural site formation processes should be set in an environmental framework that includes spatial,
temporal, physical and biotic parameters. A better understanding of site formation will give us a more
complete "tool-box" to interpret inundated Paleoindian/Early Archaic sites.


First Floridians and Last Mastodons

By Dr. S. David Webb

A score of collaborators from diverse institutions in Florida, Michigan, Minnesota and California,
completed their contributions to the ARPP book early this year. After further editing and illustrating, the
book will be bundled off to Plenum Press for publication. The diversity of contributions is quite
remarkable, a tribute to the wealth and variety of evidence preserved in the river bottom and recovered
by ARPP underwater excavators.

Several early chapters set forth the regional geology, especially the late Pleistocene of the Aucilla River
and Apalachee Bay. The stratigraphy and carbon-dates that establish the chronological framework are
presented in excruciating detail. The fauna and the flora are analyzed in multiple contributions and then
synthesized to give a sense of the regional environment. Two chapters are concerned with stable
isotopes and their environmental significance. Two other papers present details of the mastodon digesta
found in abundance in certain strata. And last but not least, of course, are several studies of cultural
remains from early and late Paleoindian horizons.

In broadest terms this book will provide the most intensive prehistory yet known of a late Pleistocene
and early Holocene setting in Florida. The environmental and chronological studies provide a sound
frame onto which the rich tapestry of faunal, floral and cultural evidence is woven. It has long been
known that Florida's submerged sites yield some of the richest evidence of Paleoindian cultures in North
America, but this is the fullest test of the "Oasis Hypothesis" that purports to explain Florida's
underwater wealth. The title, First Floridians and Last Mastodons captures the essence of this long
book. It will probably be published during the year 2001.


Clovis site distributions

By Mark Muniz

The goal of this paper is to further attempts at modeling Paleoindian subsistence/settlement strategies by
first reconstructing paleohabitats based on fossil pollen evidence, then evaluating mammal diversity for
those reconstructed areas, and finally plotting site distributions in relation to those habitats. Due to space
limitations, only Clovis site concentrations will be addressed here, although data for Paleoindian and
Early Archaic periods of Florida have been presented elsewhere in a 1998 paper by Louis Tesar and me.

Paleoenvironmental reconstruction is based on published pollen studies from Lake Annie, Lake Tulane,
Sheelar Lake, Lake Louise, and Camel Lake. To estimate species diversity, 48 mammalian species were
chosen from those occurring in the Late Pleistocene of Florida and matched to habitats that met the
dietary requirements and proposed niches of each animal. The only mammals not included in the
distribution are mice, voles, moles, and others of comparable size.

Because so much of Florida has been inundated by sea level rise over the past 12,000 years,
consideration of Paleoindian subsistence strategies clearly needs to take into account resources then
available in the now inundated region of the continental shelf, which would have then been coastal plain.
Habitats that combined both terrestrial, freshwater, and saltwater resources (such as estuaries) offered a
greater diversity of resources than upland habitats 11,000 years ago, as they do today, and were surely
utilized by Paleoindian peoples. Unfortunately, we will have to wait until pollen data from inundated
regions of the Gulf of Mexico and Atlantic Ocean have been collected before a total picture of the
habitats available for Paleoindian utilization can be completed.

For the period 12,000 to 11,000 RCYBP
the habitat surrounding Camel Lake
(located about 60 Km west of 0 0t
Tallahassee) is characterized by mesic
deciduous forest with many mast
producing oak trees and abundant
moisture. To the northeast, the Lake
Louise habitat (located about 20 Km

south of Valdosta) was much drier, with
far fewer floral species, exhibiting
prairie development and dominated
primarily by oak. The region around
Sheelar Lake (located just outside of
Gainesville) was characterized by a
mesic moisture regime with broad leaf
trees declining and pine increasing. Oak
and herbs were also present, and there
was some prairie development as well.
The south-central Peninsula, represented
by Lake Annie and Lake Tulane, was a
much drier scrub and prairie habitat
with some sclerophyllous oak
woodlands on the upland regions. This
area also contained composites, grasses,
and some pine.

Prior to the extinction event of the terminal Pleistocene, the distribution of the 48 mammals chosen for
this study ranged from a high of 34 species in the Panhandle to a low of 22 species in the northern
Peninsula and 27 species in the south-central Peninsula. In every habitat, species ranged in size from the
Gray squirrel to the Columbian mammoth. During this period, sea level rose at least 15 meters.

The heaviest concentrations of Clovis sites occur along the borders between differing ecozones and
drainage basins, and range from 75 Km to 250 Km apart (Figure 1). Many Clovis sites once located
along natural levees and terraces of coastward river valleys are today inundated. As a result, this
distribution may only illustrate a part of the subsistence/settlement strategy practiced by these people.
Nevertheless, it seems that Clovis people in Florida did not focus their sites in a single kind of
environment, but instead concentrated on areas where the widest diversity of floral and faunal resources
could be obtained. For example, exploiting the region between Camel Lake and Lake Louise provides
access to 92% of the mammalian species chosen for this study, versus 71% in the Camel Lake region
and 46% in the Lake Louise region. There was undoubtedly increased diversity of floral resources along
these border lands as well.

The southern Peninsula, which most closely resembled habitats found in the Southwestern U.S., with
large grasslands, prairie, and scrub oak woodlands, appears completely uninhabited. This is unusual
given the presence of faunal resources such as mammoth, mastodon, bison, deer, and sloth that were
present (representing 56% of the 48 mammalian species), and suggests a subsistence/settlement strategy
for Florida Clovis peoples different from that employed by their Northeastern counterparts.

The very weak presence along the Atlantic Coast emphasizes the Clovis focus on the Gulf of Mexico. Of
the six drainage basins bordering the Gulf, Clovis sites are concentrated in the central four. Site
concentrations along the borders of drainage basins once again indicate a focus on areas that allowed

access to greater diversity of faunal and floral resources. Finally, distinct concentrations in both the
Panhandle and near Tampa Bay may suggest the territories of at least two macrobands.

Following the arguments of David Meltzer and others, hunter-gatherer settlement in regions with high
species diversity and accompanying low populations of individual species, should result in a generalist,
rather than a specialist, subsistence strategy. In addition, quarry and/or tool production sites should be
the only site types that are large and repeatedly visited by generalists. The location of Florida Clovis
sites along transitions between different habitats supports a generalist subsistence strategy. Meltzer's
generalist hypothesis is also supported in Florida by the many isolated finds characterizing the Clovis
presence along karst river valleys, with very few base camp sites or sites exhibiting repeated occupations
that often characterize a specialist subsistence strategy as employed, for example, by Paleoindians in the
Northeastern U.S.

Hopefully this brief discussion sheds light on Clovis subsistence strategies in Florida. Due to the
absence of faunal remains from Clovis sites, we are forced to rely on theoretical formulations and
inference to derive our conclusions. However, with more pollen data (especially from the Gulf of
Mexico) and the continued search for intact, stratified Clovis sites in Florida, we will eventually be able
to flesh out the model presented here.

Editor's Note: This paper was presented at the 31st Chacmool Conference, on Novermber 14, 1998, in
Calgary, Alberta, Canada. It is excerpted from a larger paper entitled "Peopling of the peninsula".


Aucilla River time machine

By Dr. S. David Webb

Now that our project has entered its last year of field work, I want to reveal our most important secret.
We actually discovered this secret at the end of our first season, and it has sustained us through the 15
subsequent years.

In our first explorations of the Aucilla River, we discovered that the bottom consists of two very distinct
types. There are shallow sections with hard limestone bottoms and, on the other hand, there are deep
areas filled with dark organic sediments. These latter areas often produce rich samples of fossils. The
deeper, richer areas are also usually wider, forming more or less circular patterns within the course of
the river. We soon realized that these are sinkholes that were back-filled with sediments, and it is in
these sinkholes, now merged with the river, that we discovered the Time Machine.

The only way to relate this stunning discovery is to start at the beginning. With only a few days
remaining in our inaugural field season, Buddy Page offered to show us a very rich, very deep hole;
informally known as "Booger Hole" near the middle of Half-Mile Rise. Once we adjusted to the
darkness, we saw several large bones scattered about. My eyes focused on a large radius. This long bone
from the forelimb is strongly bowed in mammoths. As I stared at the convex anterior face, I noticed that
the outer cortex was worn almost to nothing and that it was broken just at the point of deepest wear. And
as I continued to ponder the origin of that bone the TM kicked on.

As I watched, a woman came out of the darkness, picked up the radius and began scraping hides. She
yelled strange sounds to a child sitting nearby. She gave a hard thrust to the radius and I saw it snap near
its midpoint. The longer piece fell to the ground. I realized then that the time machine was playing this
scene for those of us in "Booger Hole". It also indicated to us that the time was more than 12,000 years
before the present. The experience lasted about ten minutes. Then I realized that my SCUBA pressure
gauge was about to enter the reserve zone. I was slowly carried back up to the present where the light
was brighter and people spoke English.

That experience was the first of many. I began to realize that the time machine operated only in deep
holes where the river encountered a standing sequence of ancient sediments. And in most such instances
the TM seemed to be driven by divers' intense interest in a specimen that invoked a particular scene
from the past. I also realized that the machine gave its chronological printout based on the ratio of
radioactive carbon 14 to stable carbon 12 in the sediments on location in these deep holes. As we
watched the woman scraping hides, the machine evidently commuted between the past and the present,
computing the difference in C14 levels. In the present it saw only 1/8 as much radioactive carbon as it
saw then. It registered that two and a half half-lives of C14 had already decayed, and thus based on the
half-life of 5,700 years for radioactive carbon, it calibrated that our visit was more than 12,000 years
before the present.

It also occurred to me that the machine could not operate where deep sediments were absent. In such
cases, few specimens could be found, and often, if there were some, they were mixtures of diverse ages,
presumably giving conflicting signals. On one occasion I noted that the machine's chronological sensor
spun crazily. Only a few deep sites gave strong signals for the machine. Those of us who are fortunate to
have experienced those ancient scenes, must now do our best to convey these remarkable glimpses of the
lives of the first Floridians to present and future Floridians.


More about radiocarbon dating

By David Thulman

The great promise of radiocarbon (C14) dating is that it provides a method for dating and sequencing
specific prehistoric events. On the Aucilla projects, C14 dating is used as a method for weeding out
unpromising sties that are either too old or too young. In addition, it provides a method for determining
the relative chronologies at the various sites and their relation to sites elsewhere in the world. Are we
working on some of the earliest human cultural remains in North America? C14 dating can help provide
the answer.

Given the pervasive reliance on C14 dating in archeology, it is necessary to understand the limitations of
C14 dating and how the results can be skewed and misused. A C14 date is not really a "date" at all; it is
an estimation of the number of years it would take the radioactive carbon in a dead organism to decay to
leave the amount of radioactive carbon actually found when a sample of that organism is analyzed.

For example, at the Aucilla River sites, we typically take samples of buried tree branches for C14
testing. (Wood is a very reliable material for C14 testing.) The ratio of C14 and C12 in that branch is
then compared with the ratio of C14 and C12 in a modern standard, and an estimate is made of the C14
remaining in the branch. If half the amount of C14 in the modern standard is left in the branch, the
branch should be about 5,730 years old. I say "about" since the decay of C14 is random and the
estimation of the amount of C14 is based in part on statistics. That is why C14 dates are always reported
with a "" margin of error. Typically, the margin of error reported is for one standard deviation from the
norm. Therefore, a C14 date of 10,000 200 BP on our branch sample means there is a 68% probability
(a 2 in 3 chance) the branch died sometime between 9,800 and 10,200 years ago. A common practice is
to report a C14 date as the single middle date (in our example, 10,000 years). This is misleading since
there is actually an equal chance the true date of the branch will fall anywhere within the 400 year
margin of error.

Fig. 1 OxCal chart correlating C14 and Calendar dates

As Mary Hudson explained in her Aucilla River Times article two years ago, C14 is created by cosmic
radiation in the upper atmosphere. That radiation fluctuates year to year and therefore so does the
creation of C14 That means if our branch grew at a time when relatively lower levels of C14 were in
the atmosphere, it would have less C14 when it died and would show an older apparent age than it
should. Conversely, if it grew at a time of abundant C14 it would appear younger than it should. This
differential C14 concentration may give our branch a younger C14 age than another branch that died
hundreds of years after our branch, making comparison of the two samples misleading.

The only way to resolve this uncertainty is to calibrate the C14 dates with calendar dates. This
calibration has been done by compiling a dendrochronological (tree-ring) record and painstakingly
figuring the C14 age of these tree rings. This tree-ring record now extends back about 11,500 years, and
by comparing the calendar age of the tree rings with their radiocarbon age, calibration curves have been
created to produce a calendar date for a corresponding C14 date. The differential production of C14
produces "wiggles" in the calibration curves, and these wiggles can result in a single radiocarbon age
corresponding to more than one calendar age.

There are presently a few computer programs available over the Internet that automatically calibrate C14
dates. The latest version of OxCal v.3 is fairly simple to use and produces information like the graph in
Figure 1. The program can be downloaded from http://units.ox.ac.uk/departments/rlaha/oscal h.html. By
inserting a C14 date of 10,000 100 for our branch, OxCal produced a range of calibrated dates with
different confidences. Just like C14 dates, calibrated dates are given in a range. Note that as OxCal
translates the lab date to a calendar date it also switches from BP (before present) to BC (before Christ).
From Figure 1, we can be fairly confident that the date of our branch is between 9,700 cal BC 9,280
cal BC, and very confident it falls between 10,200 cal BC 9,200 cal BC. ("cal BC" means calibrated


years before Christ as opposed to "BC" which means radiocarbon years before Christ.)

Carbon 14 dating has revolutionized archaeology by providing a method for dating events and allowing
the comparison of events where previously their relative ages could only be indirectly inferred.
However, it should be used with caution. Hopefully, even with its limitations, it will help us better
understand the relation of our sites to the broader context of Paleoindian archaeology.

Protection. This article follows Mary Hudson's excellent description of the basis of radiocarbon dating in the

Determining the species source of prehistoric ivory

By Dr. Joan Herrera

Paleoindians hunted mammoths and mastodons here in Florida over 12,000 years ago. They made tools
from the ivory of these animals, most notably a spearlike tool. This tool is commonly referred to as an
ivory foreshaft, but recently there has been much debate about its actual purpose.

Although the Paleoindians are known to have hunted both mammoths and mastodons, it is thought that
they may have had a preference for using mammoth ivory as the material for making shafts. It is not
known if there was a cultural basis for this preference, or if it was due to some property of the material.
Whatever the reason, it will be remarkable if a significant number of the ivory tools that we test are
made of mammoth ivory. While mammoths were more common farther north, in the regions from which
the Paleoindians probably migrated, mastodons appear to have been much more prevalent here in

The proboscidean species from which a piece
of tusk came can be determined by looking at
the pattern of dentin tubules spiralling through
the ivory. This feature of the dentin is the
"Schreger pattern", and each species has a
distinctive herringbone pattern (see

The Schreger pattern is made up of alternating
bands of dark and light material forming
convex spiralling tracts through the ivory.
There are elements in the pattern that spiral to
the left and others spiral to the right. By
measuring the angle formed by tangents drawn
to the left-facing and right-facing curves of the

spirals, Dan Fisher (University of Michigan) i
and his colleagues have quantified a significant iustranl g ihe Scregerpatern
species difference between mammoths and
mastodons in these intersection angles. Fisher found that the Schreger pattern angles of mastodons
average about 124.7 degrees, and those of mammoths average 87.1 degrees. By measuring these angles
in the dentin of the ivory foreshafts in our collection we hope to determine the species from which each
foreshaft was made, and to discover if the Paleoindians did have a species preference for the source of
the ivory for their toolmaking.

The information gained from measuring the Schreger patterns in the ivory foreshafts in the Florida
Museum of Natural History collection will be added to other data from electron microscope studies and
will be analyzed, presented, and published by Dr. S. David Webb, James Dunbar, and Andy Hemmings
in their studies of worked ivory.


Blackwater photography

By Tim Barber

The first rule of successful underwater pho tography is get close. Because of its
density and the presence of suspended particles, even "clear" water absorbs and
scatters light much faster than air. Not only is the total available light reduced,
"y ybut colors are shifted toward the blue end of the spectrum as the longer wave
I lengths are absorbed first. So the less water between the lens and subject, the

The water column that we encounter in the Aucilla River contains not only a
generous supply of particulate matter, but also a chemical component, mostly
tannin, which makes this "get close" rule even more important. This actually simplifies equipment

To obtain a close focal distance with a generous field of view, use a wide angle lens. Think of looking
through binoculars backwards where you have to get really close to something to make it appear normal
size. This is the choice for rendering larger objects such as megafaunal remains or procedural shots of
divers. To get even closer for small objects, use a macro lens of at least 60mm or greater. You may lose
some context because of the narrower picture angle, but you can capture images of in situ material actual

All of the underwater photos in this issue were shot using a Nikon 8008s with an AF Nikkor 28mm
f/2.8D lens (9" minimum focal distance). This was mounted in an Ikelite SLR-AF housing. A dome port
was used to correct for the water's refraction. Since the only available light at depth is provided by our
1000 watt Snooper lights, I used an Ikelite 100 A (medium intensity) strobe, hand held.

I used Kodak Ektrachrome Lumiere 100X professional slide film for its high color saturation and
exceptional resolution. Kodak no longer makes this film, but told me their E100S and E100SW
professional films have similar properties.

What about digital cameras? At present there is equipment capable of mounting the required lenses and
approaching film's near-seamless resolution. However they're bulky, expensive, and underwater
housings are unavailable.

I think that we regulars on the Aucilla River Project tend to take our "snapshots", both underwater and
topside, for granted. After all, we're there in the field every day we know what this stuff looks like.
Then I consider the now priceless images of previous expeditions, say Howard Carter in the tomb of
Tutankhamen or Roy Chapman Andrews' crew at the Flaming Cliffs in Mongolia. I hope that one day

our pictures will have a similar archival relevance. If not, then at least we've captured some great
memories. But, if so, then maybe, just maybe, having to listen to Bill Gifford whine about his coffee will
have been worth it.


Sidescan sonar mapping

By Dr. Michael K. Faught

For years we have tried to describe the bottom
of the Aucilla River. Terms like "highly
variable, craggy, and variegated" come to
mind. There are places with rocky shoals, there
are sandy bottoms, sinkholes, and leafy
sediment beds. There are dead fallen trees,
branches and boulders. There are also a few old
docks and boats. This highly variable bottom,
in combination with the low visibility of the
dark tannic waters, makes diving in the Aucilla '
treacherous and finding evidence for !.
prehistoric peoples challenging, to say the least.
For years we have desired a way to map the
bottom of the river, to make sense of its
morphology, and to predict where we might go
to find additional sediments for coring, or
excavations, to seek out more data about
Paleoindian and other material culture
(archaeology) in the river.

We now have the capability to do this because
of a familiar piece of equipment that is being
used in new ways. In the summer of 1996,
while having dinner with Roger Smith of the
Bureau of Archaeological Research, and Brett
Phaneuf, graduate student with Texas A&M's
Nautical Program, and discussing the benefits

of Marine Sonics' Windows based high
resolution sidescan sonar equipment, I was
excited to think that this same device might
reconstruct the channels in the geological
features of the Woodville Karst Plain. (See
"Wakulla Springs Karst Plain symposium").
Phaneuf's relating how well the device worked
in a rock quarry got me to thinking about how
well it might work in the Aucilla. The usual
targets for sidescan sonar devices are
shipwrecks and other historic features
protruding from usually flat sandy bottoms.

As one of the cooperative efforts between the
University of Florida and Florida State
University, several students and staff undertook
sidescan sonar imaging of portions of the
Aucilla River in April of 1998 as an experiment
in its utility. The device, purchased by FSU's
Program in Underwater Archaeology, is a
Marine Sonics splashproof model with Pentium
CPU, 2 gigabyte hard drive, and Windows 3.1
environment. The towfish sends out pulses at
600 Khz, and the device is integrated with a
Trimble NT200D differential GPS that
determines position from satellites to an
accuracy of about 12 feet (4 meters). It is very

pains. The GPS unit and the sidescan both performed admirably, but they were unable to communicate
because of a burned out serial port. We were able to overcome the adversity by manually recording the
locational data, but the post-processing time has been greatly increased because of it.

The data consists of about 200 megs of images on CD ROM, along with a GPS position data sheet taken
every 30 seconds. We still have to lay out the track-lines and determine the placement of the images on
local maps. The device read out straightens out the river track way, but the images can be saved as *.tif
files and cropped to fit a GIS based map in proper order and alignment. The figure shown is a segment
of the Aucilla, north of Williams Fish Camp, but south of Ward Island. In this image one can discern
rocky portions and smooth sediment filled portions, some logs and evidence of erosion. The river flow is
from top to bottom, the width of the image is 150 meters.

We have scheduled another trip this spring to re-do the data so that the locational fixes are integrated
onto the images and to expand our coverage to the Page/Ladson site. The crew on the April 1998 cruise
included: Michael Faught, Andy Hemmings, Binion Williams, Joe Latvis, Thadra Palmer, Grayal Farr,
and John Davidson.


ARPP: Scientific diving to national standards

By Dr. Robert Millott



During the past three years the Aucilla River Prehistory Project (ARPP) has made over 1500 dives for a
total bottom time in excess of 1780 hours. This has been accomplished with no diving accidents. The
number of volunteer divers who participate in the project averages about 20 per field season, in addition
to the regular staff. All of the volunteers are required to demonstrate competency as defined by the
American Academy of Underwater Sciences (AAUS) and the University of Florida's Diving Science &
Safety Program (DSSP) standards. There is at least a sense that those who do dive on the project are
competent in diving skills for the task at hand.

A great deal of the diving is performed in water with mild to strong currents and low visibility, using
artificial lighting and surface supplied air. In addition, the dive sites are remote from medical support
systems. Thus there is always a need to address the potential problems associated with this environment.

Wide ranges of training and dive experience among volunteers from across the country who are new to
such activities have suggested a need for extensive review of their skills development to minimize
project risk.

The University of Florida attempts to control hazardous activities through the efforts of the
Environmental Health & Safety (EH&S) office. The DSSP is a component of this office directed to
oversee and manage all sub-aquatic activities for risk management purposes. This program is an active
organizational member of the AAUS.

The AAUS originated in part to address diving activities in science and research, and to obtain an
exclusion from the OSHA regulations 29 CFR 1910, Subpart T. This regulation placed major constraints
and expenses on all diving activity. To this end, the AAUS provided statistics and guidelines to the
government demonstrating that research diving could be conducted with a minimum of accidental

The ARPP has an excellent accident free history of scientific diving activities. With the large number of
divers (both volunteers and faculty/staff/students) and dives over the past 15 years, its progressive
support and adherence to national standards for dive safety in scientific diving can be seen as a major
contributing factor to this outstanding safety record.

The ARPP has supported and complied with the national safety standards as promoted by the AAUS. It
has as its strong support dive group a larger number of volunteers than academicians. Divers coming
from all over the US and beyond have proven capable and conscientious in assisting with the research.

The program has demonstrated an attention to details, planning and training that has resulted in
extensive scientific diving with no dive-related injuries. The basis of the diver evaluation and
requirements is the AAUS exemption from stringent OSHA rules governing commercial diving, which
was based upon a history of sub-aquatic research under such constraints with little or no accidents
resulting in diver injuries.

ARPP director Dr. S.David Webb, director of diving operations Joe Latvis, and field operations
supervisor Bill Gifford have strongly encouraged and supported diver training and performance to insure
risk management through attention to detail and careful extensive planning. The dive plans presented by
the ARPP are comprehensive and address health and safety issues with great thoroughness. Generally,
there are even "dress rehearsals" for potential problem responses (see "Lifeflight/ARPP medevac drill"),
thus demonstrating an in-depth review and understanding of the significance of any problems that might
occur in what is considered a "safe" activity conducted in a potentially hazardous site.

Wacissa bison radiography

CAT scan radiography of a Bison antiques skull reveals the broken tip of a Paleoindian point that
penetrated the surface of the animal's horn core. This bison skull was found in the Wacissa River in
1981 by Roger Alexon. Radiocarbon dates of 9900+/-200 and 11,170+/-130 are associated with it and
with other bison bones found nearby. This large date range is still within Paleoindian times.

This spearpoint wound would not have killed the bison, but it did die the same day. This was determined
when it was discovered that the bone around this wound site never had the time to heal at all. This is one
of very few known occurances of Paleoindian and extinct bison interaction in the Eastern United States.

ARPP produces educational poster

i9e I



This year, the Aucilla River Prehistory Project produced a poster for use in our educational and public
outreach programs. The poster has already been used in an instructional and outreach role at ARPP open
houses, the Florida Museum of Natural History Open House, and Paleofest'98. It has also been
presented to some of our contributors and legislators in appreciation for their continued support of the

ARPP graduate student Mark Muniz created a preliminary draft and gathered the graphic materials for
the poster, then worked with Joan Herrera to produce the final design. The background graphic is a map
of Florida representing the central theme of diversity. There is great diversity among volunteers, fossils
and artifacts recovered, techniques used, and methods of public dissemination of project findings that
serves and promotes the goals of the Aucilla River Prehistory Project.

The map marks the hometowns of those participants who come to us from within the state. The project
also attracts many volunteers from around the nation and increasingly from foreign countries. There are
also photographs of fossils and artifacts discovered by the project and drawings of quadrats with
representations of a probable Bolen culture hearth. Education and outreach aspects of the project are
represented by graphics of our newsmagazine, the Aucilla River Times, and of the new Aucilla
Mammoth display now on exhibit at Powell Hall (See "Aucilla Mammoth...").

Copies of the poster are available through the ARPP. The posters are 18 X 24 inches and in glossy color.

Volunteer Spotlight:
Melanie Damour and Don Munroe

Melanie Damour

Melanie is a first year graduate student in Florida State University's Program in Underwater
Archaeology. She received her BS in anthropology from FSU in 1998.

Raised in Weare (yes Weare) New Hampshire she has relocated to the warmer regions of the Eastern
seaboard for her education. While truly interested in shipwrecks from the Age of Discovery and
Colonial times she has paid her Paleoindian dues on the Aucilla River and at the Jefferson site in
northern New Hampshire.

Melanie has been involved in every ARPP field season since the summer of 1997, including being part
of the "lifers" group in the summer of 1998. Barely two weeks after that expedition ended she reported
(along with fellow "lifers" Joe Latvis and Bill Gifford to the Clovis Underwater '98 project based at
FSU's Turkey Point Marine Laboratory (see "Field campaigns beyond the Aucilla").

While volunteering on the Aucilla River Prehistory Project Melanie has made the shift from screen deck
surface crew to diver as well. She has made several exciting archaeological finds during her Aucilla
work including: a broken barbed fishhook, the first fishhook found underwater by us, a groundstone axe
and her first projectile point (an expedient Kirk like point made on a flake). (See "Sloth Hole site
update" for more information about some of these finds).

Don Munroe

Don Munroe was born in Miami, Florida and moved to Ocala in the early sixties. After spending time in
the US Air Force, he moved to Gainesville to attend the University of Florida and earn a degree in
Nuclear Engineering Sciences. He also earned a Masters degree in Health Physics from the Nuclear
Engineering Department. Since 1981 he has been Radiation Safety Officer for the University of Florida.

While attending the university, Don would go canoeing with friends on local rivers such as the Santa Fe,
Suwannee, and Waccasassa. During one trip on the Waccasassa he found an arrowhead and horse tooth
in a gravel bar. He was hooked, and began collecting fossils and artifacts from the local rivers. His
searches were limited to shallow water since he was snorkeling. He also began reading books and
journals about Florida archaeology and fossils, and loved going to the Florida Museum of Natural
History to study the displays of indian artifacts. One day his job took him downstairs to the vertebrate
paleontology lab where he met Dr. Webb and Russ McCarty. They showed him some interesting fossils
and artifacts and mentioned the ARPP.

After learning of the ARPP and reading early issues of the HalfMile Rise Times (now known as the
Aucilla River Times), Don decided to learn how to SCUBA dive so that he could volunteer as a project
diver. In January 1994 he took his first SCUBA class at the University of Florida and became certified
as an openwater diver. Later that year he took additional scuba classes including Advanced, Deep
Diving, and Cavern.

Don was accepted as a volunteer diver for the October 1994 field session. Unfortunately, a hurricane
blew onto the gulf coast and flooded the region. After a couple of days of watching the river rise and
surrounding land flood, the session was cancelled and everyone sent home. The adverse conditions
didn't dampen Don's enthusiasm.

Now that he was a certified scuba diver he began diving in the local rivers. His love of the hobby
allowed him to ignore to a certain extent the spookiness of diving in dark river water.

In 1995 Don was able to complete his first dives on the project. It was fortunate that he had experience
in diving dark water, because the Aucilla River can be as cold and dark as a black hole. It can also be
almost as clear as spring water. Since 1994 he has been able to spend at least a week at each field
session. Don reports "They have all been very interesting learning experiences since there have been
different field Scientific Directors overseeing the research. Being a safety diver isn't one of the more
exciting duties assigned to scientific divers, but it sure is more exciting than holding the underwater light
while Joe Latvis films the underwater excavation."

In summary, Don reflects that "As an avocational amateur archaeologist I enjoy participating in the
ARPP. You can only learn so much from books and journal articles. Listening to and learning from
professionals and more experienced amateurs really helps your understanding of the varied fascinating
aspects of Florida prehistory."

State Representative Carl Littlefield dives with ARPP

By Joseph M. Latvis

Among the many unique applications we received in response to our 1998 "Call for Volunteers" was
one from a diver who listed his occupation as "Florida State Representative from the Dade City district".
Having received encouragement from preliminary discussions with ARPP director Dr. S. David Webb,
Carl Littlefield had formally registered his interest in participating for a week on the May/June field
season's dive roster. He was not deterred by learning that the University of Florida's Diving Science and
Safety Program requirements (beyond already possessing a recreational SCUBA diving certification)
included a rigorous physical examination, written SCUBA test, and in-water swim and SCUBA skills
tests. Nor was he put off by the prospective tent-living conditions at Nutall Rise base camp that all roster
participants subscribe to. And so roster dates were mutually agreed upon for the upcoming field season
(along with thirty-three other volunteers).


under construction

Carl arrived at base camp the morning of May 18, and after the usual morning operational/scientific

briefing and introduction to that particular day's crew, loaded his dive gear into the project pickup trucks
for transport to the shuttle vessels that would take us all to the Latvis/Simpson site already under
excavation at the Little River section of the Aucilla. As with all divers new to the DSSP certification
program who require swim and scuba skills verification in the field, Carl was put through the standard
drills by field operations supervisor Bill Gifford that morning. Now fully certified as a scientific
research diver Carl was short-cycled into the operations roster for his first project dive that afternoon.

After a detailed pre-dive briefing, Carl and I departed the surface of the Aucilla for the working
excavation below. Winding our way among blowdown trees that guarded the one by one meter
excavation unit, we arrived on the bottom for the beginning of our scheduled 2-hour dive. Carl displayed
the comfort and confidence in the low-visibility, high-current environment that good recreational diving
skills typically engender. I introduced Carl to the new skills he would practice with subsequent lead
divers in pursuit of the secrets hidden within the Aucilla's riverbottom sediments: Snooper light tending,
fossil and artifact recognition/identification, sediment characterizations, provenience control, dredge
excavation, mapping, photography, and field specimen protocols. Carl responded with the cautious
enthusiasm typical of our most conscientious divers, eager to acquire the scientific diving techniques
requisite to helping explore these fascinating places. A post-dive debriefing clarified subtleties of the
preceding dive that were impossible to discuss while on the bottom. Carl returned to his legislative
responsibilities that evening, having successfully completed his certification with and introduction to the
Aucilla River Prehistory Project field operation.

He subsequently returned to the Nutall Rise base camp on June 1st and pitched his tent for a full week of
research diving paired with the likes of field scientific director Matt Mihlbachler, Bill Gifford, Bill Reed
and Joe Latvis. Carl endured all the indignities of life in the field that we commonly share, from in-river
bathing to heavy gear lifting to muddy swamp footing to insect attacks to "the big
shakes" (hypothermia) to a turn on the KP roster, all with the good cheer and camaraderie shared by all.
He must have enjoyed the experience, because in July he took advantage of the reciprocity afforded him
by his newly acquired scientific diver certification to participate in a five-day research cruise with
Florida State University's "Clovis Underwater '98 project, exploring Paleo-Aucilla archaeological
sites now inundated by the Gulf of Mexico. His enthusiastic support for Division of Historical Resources
Special Category Grant funding of this sister project to the ARPP will permit research to continue
offshore for two more field seasons in 1999 and 2000.

Editor's note: Carl Littlefield relinquished his State Representative's seat in January 1999 to join the Bush
administration as Developmental Disabilities Coordinator and Assistant Secretary for Developmental Services
in Tallahassee.


Lifeflight/ARPP medevac drill

By Joseph M. Latvis

Before each field season begins, the ARPP publishes and distributes its site-specific dive plan and
emergency evacuation protocols to (among many other organizations and individuals) the two medevac
helicopter services nearest to our remote Aucilla River sites. In the event of an injury requiring rapid
evacuation to a hyperbaric chamber or level one trauma center Lifeflight Helicopter Service stands by as
primary air transport to Tallahassee Community Hospital, 20 minutes distant (Shandscaire Helicopter
Service stands by as secondary air transport to Shands Hospital, 40 minutes distant.) Although each
ARPP crewmember also receives a copy of the logistically complicated emergency evacuation
procedures (which involve recovering a diver from the riverbottom to the surface, to a chase boat, to the
operations vessel, to an evacuation vessel, to a boat dock, to an evacuation vehicle, to a predesignated
helicopter landing zone) we have never had to activate these procedures.


under construction

Shortly after the October '98 field season commenced, Lifeflight supervisor Tom McNab contacted me

to explore the possibility of conducting an emergency evacuation drill. With project director Dr. Webb's
enthusiastic endorsement, October 8th was designated for the joint exercise. Lifeflight helicopter pilot
Don Spells first flew to our primary landing zone LZ-2 at the Ladson property in the open field on high
ground at Nutall Rise to verify that ARPP dive plan coordinates were accurate. Because the river was in
flood stage, this LZ could not be reached by our evacuation vehicles without traversing inundated access
roads to deliver the simulated patient. Pilot Spells consequently wheeled the BK 17 helicopter several
miles south to our secondary landing zone LZ-3 at the Taylor County Aucilla boat ramp.

The helicopter landed in an open field adjacent to the boat ramp just as our simulated evacuation vessel
arrived from Sloth Hole site. ARPP's lead medical personnel (Metro Dade Fire Department paramedic
Mike Simpson, Florida EMT Joe Latvis, and operations supervisor Bill Gifford) met with Lifeflight
supervisor McNab and flight nurses Tracy Evans and Kristy Fishback. As the rotors wound down, the
rear bay doors were opened, and details regarding patient intubation, packaging, and oxygen
administration were discussed, as well as helicopter protocols, communications links, and response
times. Field scientific director Andy Hemmings provided an impromptu fossil/artifact clinic for the
flight crew, before they boarded the helicopter and lifted off for the return flight to Tallahassee. The
compelling intensity of the drill reinforced the field crew's belief that situations requiring such
emergency medical intervention can indeed occur, and that if and when they do, our CPR/first aid/
oxygen provider training and evacuation procedure preparedness are the best response to serious injury
or illness.


Field Health Beat: Hypothermia

By Mary Gouchnour Hudson

ARPP field crew are susceptible to Cold Exposure, or Hypothermia, due to the environmental conditions
in which we live and work. Cold, wind, and rain during both the May/June and October/November field
seasons may intensify the effects of working drenched in water on the screendeck and topside during
other operational activities. Cold temperatures in October/November can be especially brutal. Two-hour
long dive rotations drain heat rapidly from the divers, with water temperatures averaging in the low-to-
mid seventies during May/June and in the low sixties in October/November. Hypothermia may occur in
80 degree tropical waters after long dives, and it may strike hikers caught in inclement weather in mild
temperatures, so the cold Aucilla River water here is a real concern.

Hypothermia occurs when the body's regulatory mechanisms are overwhelmed, and the normal body
core temp of 98.6 F begins to fall. There are three main stages : mild, moderate, and severe.

direct safety hazard.

Once these symptoms are recognized by the diver or his partner, the dive should end and the appropriate
supervisory personnel notified. Topsiders should take a break and warm-up. Screendeckers should also
take a warm-up break; if you are pulling lone duty, then signal the divemaster to send either additional
weather gear and a warm beverage or replacement personnel. Mild hypothermia is usually a non-
emergency and can be treated with warm beverages, a change of clothes, and rest. If the victim does not
improve within thirty minutes or seems to be getting worse, suspect moderate hypothermia and notify
the divemaster and senior most qualified medical crew on site.

Moderate Hypothermia (95-90 degrees F)

Signs and symptoms can include: weakness, drowsiness, mental dullness, memory impairment,
decreased or suspended shivering, increased muscle incoordination, stumbling gait, confusion, and
slurred speech. The victim will be awake, but may appear confused, apathetic, uncooperative,
withdrawn, and uncommunicative. At this point, a cold exposure emergency should be declared, and the
divemaster on duty and senior most medically qualified crew member will coordinate emergency efforts.
Crew members should stand ready to continue operations or assist with the rescue effort as directed.

Typically, passive re-warming procedures include changing from wet clothes to dry ones, warm
beverages, blankets between the victim and the ground, covering the head with a warm hat or a blanket,
covering the victim with blankets, and shielding from rain and/or wind. Any further rewarming
procedures are generally not recommended; however, in a remote setting, the emergency directors may
provide further instruction if necessary. They will then proceed with the emergency evacuation plan as
they deem necessary.

Severe Hypothermia (89 degrees F and below)

Signs and symptoms can include: no shivering, paradoxical undressing, complaints of loss of vision,
inability to follow commands, inability to walk, muscle rigidity, decreased blood pressure, decreased
heart rate, decreased respirations, dilated pupils, unconsciousness, and the appearance of death. Rough
handling or improper re-warming may cause cardiac arrest, so extreme care is needed. After passive re-
warming, personnel should be prepared to initiate CPR if indicated, taking care to treat the victim gently.
Emergency directors will initiate the medical emergency and evacuation plan, and personnel should
stand ready to assist according to dive plan protocols.

The ARPP's commitment to safety through education, policy, and enforcement continues to provide
staff, volunteers, and visitors with the best security possible in a potentially hazardous environment.
Good science, combined with dedication to safety first, allows us all to enjoy the wonders of the Aucilla


Role of the crew chief

ByBob Coughter

The resources required to design, fund, supply and staff a scientific field project and the logistical
requirements for organizing and successfully operating it can be quite daunting. A perusal of the many
articles herein reveals that the Aucilla River Prehistory Project is just such a project. The ARPP is one of
the more challenging projects to be found within the spectrum of archaeological expeditions. Our
reliance on a wide array of specialized equipment and the sometimes taxing conditions in which we live
and work make this endeavor a tricky one.

In order to mount productive field seasons year after year, every member of the project is called on to
give 100% of their effort toward achieving our research objectives. Often, everyone delivers 110%. It
could go without saying, but it shouldn't, that the cooperation and talents of many dedicated individuals
working toward a common goal make the ARPP so successful.

The role of the crew chief is
not so easily defined as to
allow a tidy list of duties. u

personnel management.

Within the field operations organization, the crew chief is found among the frontline levels of the project
staff. As with other staff positions (field scientific director, operations manager, operations supervisor,
equipment specialist, etc.) a crew chief has at least one, but often several field seasons of experience on
the project. This is because she/he must be familiar with not only what needs to be done, but precisely
when, and how to do it. Often the crew chief will be directed by the field scientific director or operations
manager to resolve a problem, or delegate the responsibility and authority to a qualified volunteer. Being
so familiar with operational procedures, the crew chief is certainly free to take the initiative in carrying
out necessary activities, thereby relieving some of the task overload from senior staff members.

Since the ARPP tends to attract members who return for multiple seasons, it makes delegating
assignments easier when just about everyone already "knows the drill." Most of what needs to be done is
reviewed during the morning meetings (via the omnipresent "punch list"), and anything else is taken
care of as it happens throughout the ensuing day (and often into the night). As you can see, flexibility is
an important attribute of an effective crew chief, as well as dependability and sagacity.

As I mentioned, there are some duties that the crew chief typically takes care of. Formulating an
equitable daily K.P. roster is the responsibility of the crew chief, a necessary and often thankless job
(sigh). But, as they say, "an army marches on its stomach". The crew chief also helps make fuel and
supply runs, because only university employees are permitted to drive project vehicles (due to insurance
considerations). Similarly, providing transportation to and from the site for out-of-town members that
need it can be addressed by the crew chief. Refilling SCUBA cylinders at our Nutall Rise base camp,
recharging the air bank on the Florida State University campus (when properly trained), and instructing
others familiar with SCUBA equipment are often chores for the crew chief.

In addition, piloting project vessels, monitoring the operation of equipment on site, instructing new
members in the various field procedures, and helping facilitate the safe and smooth performance of
project activities are all charges of the crew chief. Crew chiefs are also routinely designated lead divers
in daily roster buddy team assignments. Their skills and experience make them valuable role models for
less seasoned volunteers. It's not an easy job, but everyone's effort and passion pay off. I can say that I
understand how an orchestra conductor feels, as we perform our symphony of science and discovery
each field season.


International volunteer's ARPP story

By Susan Verberg

Having worked in the Dutch National Museum of Natural History for the previous five years, I looked
forward to attending the FLMNH Open House in September, 1998. It afforded me not only a look
behind the scenes of their collections, it also showed people what kind of field trips had been going on.
That's how I came to talk with Andy Hemmings from vertebrate paleontology, who was very
enthusiastic about 'his' Aucilla River Prehistory Project. I saw some documentary a long time ago about
digging up mammoth bones in dark river water, and that picture always stayed with me. I wanted some
day to do something like that. And here I saw pictures and heard people talking about exactly the same
thing! I really wanted to go with them...

Fortunately for me Andy was very optimistic about my chances to participate in this exciting research.
He gave me a lot of information and telephone numbers, and persuaded me to call Joe Latvis, even
though the application deadline had already expired. Only three weeks before the October field season
would start, I had found out about it! After filling in lots of forms I was certified as a non-diver. I was
surprised, but happy I was accepted after applying on such short notice.

It was very interesting for me to find out all about Floridia's natural history with real examples. For
Dutch people sinkholes are something from another planet. Only a small part of the south of the
Netherlands even has limestone. That part does have some nice caves, especially just over the border in
Belgium, but sinkholes seldom appear. Although some fossils occur, they are mostly in the southern part
and mostly invertebrate limestone fossils. I have found only sea snails, oysters, echinoderms and lobster
or crab limbs. Once I found a print that very well could have been from a dinosaur (that place is famous
for it's rare dinosaur footprints) but I'm still not sure.

For mammal fossils in the Netherlands one has to go offshore to the North Sea. My grandfather lives on
one of the small North Sea Islands, Vlieland, and he made a living fishing for small shrimp in the old
days. He had a fishing boat with big nets that were towed over the bottom of the sea, and in addition to
shrimp, he also caught mammoth bones, WW II bombshells and a giant deer antler (he used for years as

a hat rack). In the same mode, the Dutch natural history museum annually rents a dragging boat to
search for Ice Age fossils. The Netherlands does have its fossils, but they're rather hard to get at.
They're not as numerous or as easy to find as here in Florida! A sloth skull in someone's back yard or on

Unfortunately I haven't been able to go on field trips with the Dutch museum. When I was there
everybody was working hard on building, moving and mounting exhibits for a new collections and
exhibition museum, which finished last April 1998. Next summer a big expedition to the Philippines is
planned, and I probably would have been a member if I still worked there. So I can't really compare
field trips, but I did hear from the ornithology curator who, after looking at my ARPP pictures described
this one as rather luxurious, and not like he was used to. But that's probably because the Netherlands
doesn't have a lot going on, and most expeditions go abroad. What is more interesting than a nice
tropical country such as Indonesia or the Philippines with tremendous wildlife (but poor living

For me the ARPP's October '98 field season was quite an experience. I haven't been on a river with so
much current before (flat country in the Netherlands doesn't generate a lot of current), and it was
interesting to see all the preparations required to work down there. Sadly I'm not too fond of pitch-black
water either, and there was a lot of that at the Aucilla too, as well as big spiders, no-see-um's and killer-
mosquitoes. I am not a diver, and that left me unfamiliar with the procedures, but to me it looked like
this: The divers make themselves ready on the dive operations boat, which is exclusively for them, their
gear, and the divemaster and safety diver. They always dive in pairs, and they work two sites
simultaneously. In a nylon mesh bag pieces of surveyor's tape with the site numbers, plastic ziploc bags
and a clipboard with a pencil were taken down. The divers use surface supplied air, but they do wear
SCUBA tanks in case of an emergency. When they are ready, the air hose is connected, and they go into
the water to one of the sites. Each site is marked on the surface with a colored styrofoam ball, and the
divers use the attached jugline to find the sites more easily in the cola-like water.

When the divers go in, the two screendeckers canoe out to the floating platforms to check both dredge
pump motors and fuel them. When the styrofoam ball in the water is pulled down two times by the
divers, the dredge belonging to that ball is started up (three pulls on the float means off). Unfortunately
this is not always as easy as this reads; the motor can be stubborn, flooded, choked or out of gas, the
couplejet can be leaking air, which can cause problems, such as hardly sucking any water, or too much
air (then it has to be back flushed, and everybody will be wet). But normally everything goes well, and
the screendeckers have two hours of endlessly noisy, boring, searching, scraping, looking for minute
fossils and pieces of surveyor's tape with unit numbers or level changes. Everything that has been found
in between two tape change markers has to be stored in a separate ziploc bag, with every bit of known
information written on the side.

I am told that underwater the divers are excavating endless heaps of mud, leaves, sticks and stones into
the dredge tube in claustrophobic midnight, so that might be hard work also. And when they find
something interesting they record its context by taking pictures, making drawings and sometimes video
of where, how deep, and what is found. Whenever something rare or fragile is exposed the dive-team

will bring it up expeditiously. Everything found on the screendeck either does not require mapping or
was missed by the divers. So they get to carry the neat stuff up and show it to everybody, including the
sunburned or freezing cold screendeckers...

I knew after a couple of hours on the screendeck why it wasn't a problem to come on such short notice.
The work isn't very exciting, and after six hours of endless motor noise in the middle of a pitch black
river fossils do seem less interesting. And I can imagine not everybody will think that's such a good way
of spending his or her free time. We screendeckers found hundreds of bones, including pieces of giant
turtle and mastodon, but also a bone fish hook, two ivory foreshaft pieces, a couple of canine teeth, a
camel molar and a rabbit mandible that the divers either didn't see or sent up anyway. I really liked to
see the big bones the divers brought to the "bone boat" during lunchtime. And of course there is the
wildlife; all those alligators cruising, big turtles sunning, small lizards running, cute butterflies, big
kingfishers, turkey vultures everywhere, white ibises and ugly cormorants. They helped a lot to make the
experience absolutely impressive (just like my mosquito bites). My average of one roll of film a day
wasn't really a lot, if I tried to record everything around me that happened!

All in all I liked this fieldwork a lot, and I'll try to get my divers certificate to participate fully next
season (see "Beneath the surface..."). And for anyone who is still interested after all the above, I would
strongly recommend that you apply for one week and participate fully! The screendeckers always need
an extra pair of hands if available, and you'll gain an experience for sure. Whether it's "not too bad, I'll
think about it" or "I'll definitely come back next season!", it's all up to you! Diving in cold cola or being
fried on a raft, it might seem a strange way of dealing with free time. But it certainly made my first
experience with Florida's natural history an adventure of a lifetime!


Beneath the surface: both sides now

By Susan Kane

The jug disappeared below the surface of the water once, and then again. Two pulls, it was the signal
from the divers on the river bottom to start up the dredge. Push of the button and as the motor caught, a
huge spray of water shot across the screen deck and out into the river. Quickly we pushed against the
pump discharge to drop the stream of water to a controlled flow. So starts my first day as a screen deck
operator on the Aucilla River Prehistory Project. We had already tied off the dredge rafts downstream of
where the divers would be working, but close enough so that the dredge suction hose could reach. Also
we had anchored the dive flags strategically to alert passing boats of divers in the water. The engines
which supplied power for the operation had been checked and refueled. We had been briefed in the pre-
dive meeting as to which units were going to be excavated, and we had prepared our field specimen bags
with the proper labels. The day was to be a wonderful learning experience, not just for me, but also for
the hundreds of people that came to visit the site later that day; for this was the project's June Open
House. For me however, it wasn't just a visit, it was the beginning of something which would change
my life.

I had just finished doing field work on the
Allendale Expedition, a paleoindian
archaeology dig on the Savannah River in
South Carolina, but it had been a terrestrial dig
as all of my previous archaeology experiences
had been. The riverine environment was all
new to me, and learning to identify the
abundant floral and faunal remains we were
collecting was fascinating. It was very rare
however, for an artifact to come up on the
screendeck. I learned why later, when the
divers finished their two hour shift, and I had "
an opportunity to examine the wonderful array -

of artifacts which they had excavated, mapped,
and collected underwater. Even though I was
on the screendeck working in the sunshine, it
was I who was working in the dark. It was the
divers, deep in the black waters of the Aucilla
River, who were bringing the old world to
light. I wanted to be there for the discovery.

I was invited back for the fall field season, and
when I told Operations Manager Joe Latvis of SXhtan Kane working the .eriteen-
my desire to become a research diver he
offered me nothing but encouragement. If I
could do it, I would be welcomed as a diver.
My first challenge was to become SCUBA certified. I enrolled in recreational SCUBA classes with
Charleston Scuba, a very reputable company in my hometown of Charleston, SC. My summer was
packed, I was working full time running outdoor adventure camps for children, and was also taking two
college classes at night, but SCUBA certification was at the top of my list of priorities. By the middle of
August I had passed my written exams and all of my checkout dives. I was a PADI (Professional
Association of Diving Instructors) certified diver. Now I had to satisfy all of the University of Florida
Diving Science and Safety Program (DSSP) requirements. The American Academy of Underwater
Sciences (AAUS) certification were the national credentials I would receive when these requirements
were met. The DSSP requirements included a full physical (with blood tests, an EKG, and chest x-rays),
as well as a written exam, a swim test, and a practical exam of my SCUBA skills in the water. In
addition, I had to provide proof of current certification in CPR and First Aid, and as a research diver I
also had to be certified as an Oxygen Provider. I already had my Wilderness First Responder
certification, so I only needed to register for the oxygen class and make an appointment with my doctor
for the physical. With these requirements successfully passed I contacted Joe Latvis about the remaining
tests. Since I lived out of state, arrangements were made for the examinations to be taken in the field
before I would be allowed to dive. I was responsible for bringing my own SCUBA gear to the dig,
though tanks would be provided. I had already spent hundreds of dollars on becoming certified, and as a


The written exam was over. I had passed. It was much more in-depth than the PADI exam had been, and
I was glad I had prepared for it. I had also been swimming every day in order to prepare for the swim
test, and the months of training had paid off. But now came the real test, in the dark waters of the
Aucilla. The river had been way over flood stage and was much blacker and swifter than usual. It was
also very cold, in the sixties, which helped to dispel the fact that my shaking might be caused by nerves.
Going under into total blackness with only a hand-held light giving about a foot of visibility for the

practical exam was a bit daunting. All of my SCUBA gear had to be taken off and put back on, and
emergency procedures had to be enacted as if I, or a diving buddy, were suddenly out of air. All of these
SCUBA skills were thoroughly checked by operations supervisor Bill Gifford to assure my own safety
and the safety of anyone I might dive with. It all went well and I was duly congratulated upon my return
to the surface. I was certified and could now begin my training as a research diver.

Every day for the next ten days I had an opportunity to dive with a different experienced archaeology
research diver. I learned to handle a snooper light while my buddy worked, to excavate with a dredge, to
map artifacts, verify coordinates and to map units in an underwater environment. I also learned the thrill
of discovery, of bringing to light remnants of a long-ago world from the cold black waters of the Aucilla
River where they had been hidden for thousands of years. The most exciting find for me was the section
of mammoth jaw recovered with teeth intact. I loved my experience beneath the surface as a research
diver and plan on attending graduate school in the coming fall to study underwater archaeology, but I
still take my turn on the screen deck whenever I am not diving, for the joy of discovery can be found on
both sides, above and below the water. The last five minutes of my last day on the river I was working
on the screen deck when I found a projectile point which had come up through the dredge. It was my
first one. I was delighted, and I will remember it always.


Senior beat: return to the Aucilla

By Jewel Pozefsky

It seemed like only yesterday when I volunteered to join the spring 1995 ARPP field crew. Despite it
being my second ever experience with camping, it was eventful, fulfilling, and definitely different! My
two buddies, Jody Barker and Terry McKibben promised to see that my camping would be something to
remember. Well, no one thought the heavens would open up the one night. Tents do fill up with water,
and I was grateful that there was room in the bunkhouse (that is, once we moved Joe's dog!). I felt like a
sissy, deserting my buddies, but it wasn't long before they too joined the group in the bunkhouse!.
Cozy? you bet! The meals were scrumptious, especially the spaghetti and meat sauce, and we did have
time to relax and have many entertaining discussions. It doesn't take long to become friends in such
close quarters!! The days were filled with gathering fossils on the dredge, and watching Jody, Terry, Joe,
Andy, and Joan get ready to see what they could find and record on film. Made me think more seriously
about learning to dive, which I am doing now. There were two of us on the dredge most of the time, but
I was the only one bundled up like an eskimo, because the huge dredge hose didn't always spurt out the
water and fossils where I wasn't. This Florida native wasn't used to such cold water!

The thrill of finding half a bone pin made my week, though. In fact, if I remember correctly, the other
half was brought up by one of the divers. Naturally, I was jealous of the divers. It must be a wonderful
feeling to be underwater and, after fanning the sand, to find artifacts that have not been touched for
thousands of years. The mastodon's tusks were still down there when they were working the bottom. I
wondered if I would ever see them, not knowing then that three years later I would be able to study the
seasonal growth patterns revealed in a longitudinal section of these magnificent tusks.

The time went too quickly, but despite my "slight" problem with the downpour, I had hoped to return
yearly, only to find that I wouldn't be free until October, 1998. My tour of duty on the 1995 ARPP roster
was prior to the end of the field season, when all that equipment had to be recovered from the river,
serviced and stored for next season. I wondered what that entailed. How much work could that be?? It
was a good thing there were many hands, because the equipment didn't get there by osmosis and had to
be returned by us. It was good meeting old friends, but this time, yours truly slept in the car no more

tents for me. Also, we didn't have to do any cooking, because meals were brought to us from Perry. This
time there was no rain, BUT did we have mosquitos? It was difficult sitting outside at night and almost
impossible to outrace them getting inside the car. One should never spray the outside of a car with insect
repellent the coating on the outside mirrors will forever be evidence of those fierce insects. However,
they only came out at night!!

Before we broke site camp, a professional film crew came to document our field activities (see "ARPP
featured in FLMNH video"). It was fun watching them set up the mirrors, the cameras, the 'actors', and
seeing how many takes were needed (actually 16 for the diving action and 5 for the screendeck, with
yours truly reenacting the discovery of an artifact). There were other fossils coming up, but nothing as
big as the projectile point they wanted to show. Once the filming was completed we began dismantling
all the operations equipment for transport by vessel back to base camp at Nutall Rise. After transferring
the gear from vessels to trucks, we then had to make a run to Thomas Farm, eventually ending up in
Tallahassee for dinner. All the canoes, boats, hoses, buckets, fossils, chairs, etc., etc., had to be stored
for the next season. Dr. Webb, Bill Gifford, Andy Hemmings, Bob Coughter, and many others made
light work of returning all this stuff. Certainly couldn't do it with only a few hands. It was enjoyable
seeing the ending of the project, and I anticipate being able to join the group next year! It is an
experience not to be missed. Where else can one find good friends, good food, great music, and all the
mosquitoes in the area.


Field campaigns beyond the Aucilla

By Thadra Palmer and Melanie Damour

Thadra Palmer

My summer of '98 field campaigns began in the Virgin Islands. The National Park Service was
conducting archaeological excavations on seven sites located on a small island called Water Island,
under the supervision of Dr. David G. Anderson. Water Island is located right off of St. Thomas, and is
only two miles long by one mile wide. Water Island is owned by the US Army and is slowly being
turned over to the local government. Before the island could be completely handed over an
archaeological survey was required to determine if there were sites in need of protection. One of the
largest sites was Carolina Point plantation which had formerly been owned by a freed black slave who
had bought the plantation and owned several slaves himself. The site includes the main house, a kitchen,
an overseer's house, several slave cabins, and other additional buildings. This main house included one
room that had burned along with a large amount of china. This room alone yielded more artifacts than all
of the rooms combined. It was hot and sticky work cutting down the jungle just to dig. But hey, this was
the Virgin Islands, so after a long day of work you could walk down to the beach and go snorkeling in
the crystal blue water. After six weeks in the Virgin Islands I headed to Italy.

For the past twenty years Florida State University has been conducting excavations in Gaiole de Chianti,
Italy. The site is called Cetamura (walled city), and has Etruscan, Roman, and Medieval occupations all
stacked on top of each other. This year's work concentrated on two areas, the first being an old well. The
well started at 6 meters at the beginning of the season, and by the end of the season reached a depth of
13 meters, and still kept going. Building rubble, tiles, and ceramics were all recovered from the well.
The second area was the fortification, which is known to date to Roman times with Medieval material on
top. It was hoped that the Romans had expanded the wall from the Etruscan occupation and that by the
end of the season we would have moved enough material to reach the possible Etruscan level, but that
did not transpire. The unit for the fortification was six meters square, and most of the Medieval material
had been removed. Several coins were found, and a bronze mirror handle was also recovered. The area
of Chianti reminds me of Napa Valley, CA, with grapevine and olive trees covering the hill sides. Of
course Chianti wine was the main crop since this is where Chianti wine originated. We ate dinner at an

Italian restaurant, and I quickly found out that Italians really do eat pasta every night. After six weeks in
northern Italy, I spent two weeks traveling to Rome, Munich, Paris and London. It was a busy summer
for me, and I was actually happy to get back to Tallahassee, if only so I could stop living out of a

June and July with Dr.
Michael Faught and Chuck Meide at the Clovis Underwater 1998 Project (see "Paleo Aucilla Prehistory
- Clovis Underwater '98"). I was a crew chief for Chuck Meide in the St. Marks River portion of the
Clovis Underwater '98 Project which comprised the survey of several shipwrecks and river bottom sites.
The majority of the project was spent surveying and mapping the remains of a mid-19th century wreck
located on the western bank of the Wakulla River at Fort San Marcos de Apalachee. Other shipwrecks
surveyed include a modern wreck that is mostly intact and another wreck which may be the remains of
the vessel "Spray". Some survey and sampling of prehistoric and historic refuse scatter on the bottom of
the St. Marks River, in Newport, Florida was also completed.

In November, I organized and directed a four day survey of a modern wreck located near the St. Marks
Lighthouse. The project was part of a class at FSU which requires each student to develop and run a
project using diving techniques in science. After obtaining an Archaeological Research Permit from the
Department of Historical Resources, I was able to implement my project. Four days were spent mapping
and measuring the wreck to try and identify remaining structures. The wreck was a subchaser in World
War I that was later used by the State of Florida Shellfish Commission. With a busy summer and fall
behind me, I am gearing up for another busy year full of archaeological projects with more emphasis on

shipwreck survey, my primary interest.


Swallow-tailed Kites of the Aucilla

By Grayal Farr

On the Aucilla our mantra of priorities is: "Safety, Science, and Smell the Roses." Part of "smelling the
roses" has always been our enjoyment of the natural setting and the wildlife around our excavation sites.
Of all the wildlife, the most charismatic is the Swallow-tailed Kite, Elanoides forficatus. Elegant, with
white head and underparts, the bird's back and wings are a shimmering, reflective, blue-black. This
raptor is striking even in repose. Happily, we seldom see them in repose. They feed, and even drink, on
the wing. And, as Peter Matthiessen writes in Wildlife in America, they "are the most graceful of
hawks." The bird guides echo that observation. Dunne, Sibley, and Sutton, in Hawks in Flight, say that
"they quarter the wind flawlessly, in total aerial control" and "Time seems to have suspended for the
bird." Just as surely suspended in time, for the ARPP staff and volunteers, are the moments when the
birds visit our sites. The big kites are magic everyone feels it.

Magic or not, they are also threatened. As late as the early 1900s, the birds nested far up the major
Mississippi drainages, even into Minnesota. By the 1940s their range had shrunk to that of the present.
E. forficatus nests in much of peninsular Florida, and west in the panhandle to the Apalachicola River.
From there west to the Sabine in Texas, and north to the Santee in South Carolina, they nest only in
isolated enclaves along coastal river swamps. Matthiessen notes that they share "the tameness of all
kites" and most researchers attribute their decline primarily to casual shooting.

Swallow-tailed Kites usually begin to arrive
along the Aucilla in late March, about a month
later than they are first seen in southwest '
Florida. Researchers suspect that the south
Florida arrivals may have come across the
Caribbean, and that our local ones have
followed the Gulf coast, but little is actually
known about migration routes or migratory

They nest in tall trees or snags, preferentially
those in standing water, in locations with good
access to open areas possessing high
populations of favored prey. Wooded river
swamps and pine fringes along flood plains
offer these conditions, so the Aucilla is ideal
habitat. Because the kites evolved to take
small, easily subdued prey, they lack the grip
strength or lifting capacity to manipulate sticks
and large twigs. Their nests, as a result, are
rather flimsy affairs. Nest collapse or
blowdown is a common cause of nestling

i- q f 7 .le c.- eawf
I -*^ -r /

e1 -%-a ido a fIrfi 0 oro"Wvou

The main cause of nestling mortality is sibling rivalry. The young birds compete, and the adults soon
begin to feed the larger of their offspring preferentially. Nestlings are known to kill one another.
Swallow-tailed Kites typically lay two, rarely three, eggs. They almost never fledge but one young bird.

On the river we often see them take frogs and lizards, so we tend to think of such animals as their
primary prey. In fact, both adults and recently fledged young feed primarily on flying insects. They are
especially adapted predators of wasps and other biting, stinging invertebrates. Kites have the thickest,
most spongy stomach linings of any raptor. They have been found with stomachs full of dangerous
wasps and even fire ants, the latter possibly gleaned as one of the floating masses which fire ant colonies
form when their nests are flooded out. They also snatch wasp's nests, eat the larvae, and weave the
wasp's nests into their own. The reason we so often see them with small vertebrates is that these are the
foods provided to nestlings. During the May/June field season, we are observing nesting birds.

The birds are quite social. They do defend a 50-100 meter radius around nests with young, but they can
often be seen hunting in groups. And especially after the year's young fledge, they assemble in
communal roosts. These communal roosting assemblages grow as the summer wanes and the birds
prepare for migration. One roost in south Florida boasts over 2,000 birds. The first birds depart in late
July, and by mid-September the roosts are empty. We seldom see them in the panhandle after mid-

During the October field seasons they are sorely missed; something vital is absent from the spirit of the
river. Which makes our first sightings in spring all the more heart-lifting.

celebration of their 50th anniversary last year the Florida Anthropological Society released a thirty
minute documentary on Florida prehistory titled "Shadows & Reflections On The Past". The theme of
this video is the quest for knowledge and understanding of the past cultures of Florida. The cultures and
sites chosen to represent the five time periods examined are:

* Paleoindians The Aucilla River
* Tequesta Cutler Ridge Mound
* Apalachee Lake Jackson Mounds
* Timucua Fort Caroline National Monument
* Calusa Mound Key

Opening scenes feature the natural environment
of the Aucilla, topside on-camera interviews with
ARPP director Dr. Webb, and underwater
excavation footage by the project. "Shadows and
Reflections" has now been picked up by the
National Educational Television Association
(NETA) for national satellite distribution. The
video was produced by Chaos Productions of Ft.
Myers. Chaos principals Stuart and Cotten
Brown previously wrote and directed the award

winning documentary "The Domain of the
Calusa", which also received national
distribution by PBS:

"A Naturalist in Florida"": video update

by Dr. Joan Herrera

'He could stop by the side of a road, and turn a little ditch into a fascinating cosmos that held you
spellbound' Karen Bj ordahl, University of Florida.

Three years ago, members of the Aucilla River Prehistory Project crew assisted WUFT filmmakers
Dennis Gaston and Dennis Ogle in reenacting scenes from the life of internationally renowned naturalist
and author, Dr. Archie Carr (see: ARPP reenacts 'A Naturalist in Florida', Aucilla River Times, Vol. 10,
1. page 20 and 'A Naturalist in Florida': an update, Aucilla River Times, Vol. 11, 1. page 20). Several
members of the ARPP crew were privileged to attend the premier of the film in association with the
awarding of the Archie Carr Medal on November 12, 1997. Since that time, the film has been shown on
PBS stations from Maine to California including about half the states in the nation, and it has won
numerous awards.

The film won first place in the biography
division at the 1998 Silver State Documentary .
Festival in Nevada. Videographer Dennis
Gaston won the Silver Award for Best Editor/
Documentary at the 1998 Florida Motion rc h ie
Picture and Television Association Crystal rc
Reel Awards. Independent producer, Letitia
Langord was nominated for an Emmy Award
for the writing. And, the film also won the
Motion Picture, Radio and TV Award from the
Florida State Society, Daughters of the A Naturalist in Florida
American Revolution.

'Archie Carr: A Naturalist in Florida' includes
stunning nature photography from around Florida. The documentary includes footage from many of the

places Dr. Carr worked with his research and his students: Everglades National Park, the Archie Carr
National Wildlife Refuge, Corkscrew Swamp Preserve, Paynes Prairie State Park, and the Ichetucknee,
Suwannee, and Rainbow Rivers.

Dr. Carr and his work inspired an entire generation of naturalists. Through his writing he continues to
uncover the wonders of natural history for people the world over. You can read a transcript of the film,
view selected video clips, and find the latest news releases about 'Archie Carr: A Naturalist in Florida'
on WUFT's website at http://www.wuft.tv/Carr.aspx. WUFT reports that many PBS stations have
requested the film and are planning to air the documentary, so watch for it on a PBS station in your area.


Aucilla River Project ends. FSU exploration on tap

by Ray Cichon

Jefferson County resident John Eveland has served as a volunteer on the Aucilla River explorations.

As such, he notes that the University of Florida project, under the direction of David Webb of the
Florida Museum of Natural History's Department of Vertebrate Paleontology, conducts two diving and
exploration sessions each year.

A six week session begins the first week of May and continues to June, with a fall session covering four
weeks in October.

Eveland notes that the project is staffed by volunteer divers and nondiving personnel.

Funded by the Florida Department of State
Historical Resources Division, the National
Geographic Society and many business and
individual donors, the Aucilla River project has
concluded its final season, he said.

However, Eveland reports, an FSU Underwater
Archaeology Program, directed by Michael
Faught, is on the horizon, and will do
underwater exploration of the Aucilla River
basin in the Gulf of Mexico.

.. ,J. .As a volunteer serving on the fall exploration,
Eveland shares with readers his observations:

Based at Nutall Rise, this past fall season's
explorations were conducted on the West Run of
the Aucilla River, south of highway 98.

Boats are used to transport personnel and
V- equipment from the base camp to the dive site.
*W Since the series of storms in September caused
the river to flood over its banks, canoes were the
only floatable object to get under the highway
John Eveland and Mary Hudson 98 bridge, providing one lay flat while going
working the sreendeck barges that
he redesigns and rebilds between

John Eveland and Mary Hudson
working the screendeck barges that under.
he redesigns and rebuilds between
field seasons With those conditions, the boats and equipment
had to be trailered overland each morning to
Williams Landing south of the site and returned
each evening.

The volunteers who had set up their tents had to move them to higher ground, because the camp, housed
in a duplex, was completely surrounded by water, as was the cabin on the opposite side of the river, used
by the project.

Canoes had to be used for transportation between the cabins instead of walking or driving. Towards the
end of the first week the river peaked then slowly receded, and river travel was back to normal by the
end of the season.

A normal day at the site consisted of three two hour dives by two teams.

Team A had two divers as did team B. For each dive, a safety diver and a dive master would be on duty
aboard the dive barge.

Divers wore full diving gear but used S.A.S. (surface air supply) from a compressor aboard another
vessel. Under normal conditions, the compressor, the generators, fuel and other equipment would be
stationed on dry land.

Because of the flooding, the project had to improvise until the water receded. The dive teams would
survey, locate, measure, map, then excavate bones and artifacts using a meter grid system.

A 6-inch and a 4-inch dredge would be used to excavate loose debris which was sent to the surface to
two screen decks anchored in the middle of the river for further investigation.

Highlighting this past season was the recovery of 24 cm of an ivory shaft (broken in 5 pieces). A tool
used by the Paleoindian dating 11,000+ years. A second ivory tool, 9 cm, was also recovered (See 'Sloth
Hole site update').

The right side of a Mastodon mandible from a late Pleistocene context was recovered from the area
where a 7.5 foot tusk was found earlier this year. Also many other Mastodon and various other animal
bones were found.

A small beveled Bolen point and two Aucilla Adzes, all about 10,000 years old and left by people about
a 1,000 years after the Mastodon and Mammoth became extinct.

Final interpretation, dating and analyses of all recovered material is undertaken at the University of
Florida Museum of Natural History after the end of each dive season.

The personnel roster varied from 14-17 volunteers daily. A project of this magnitude would not be
possible if not for all the volunteers from around the country. This season they came from as far away as
Oregon, Tennessee, Vermont, Arizona, N. and S. Carolina, Georgia, and one from Sweden.

county seat of Jefferson County, which borders the west side of the Aucilla River. The author, Ray Cichon is
