Southeastern Florida's landscape exhibits
extremely low relief. Maximum elevations
within the area of the Homestead quadrangle rarely
exceed 3.5 meters, and much of the area lies below
1.5 meters. The highest elevations occur on the
Atlantic Coastal Ridge (Hoffmeister et al., 1967).
The land surface slopes gently away from the
Atlantic Coastal Ridge toward the Everglades, the
Gulf of Mexico, the Atlantic Ocean and Florida Bay.
The geomorphic features recognized within the map
area include the Everglades, the Southern Slope, the
Reticulated Coastal Swamps, the Gulf Coastal
Lagoons and Florida Bay (White, 1970). Within the
map area, the land-surface slope is almost
imperceptible, appearing nearly flat for kilometers.
The bedrock geology of the western portion of the
Homestead quadrangle consists entirely of late
Pleistocene Miami Limestone, a marine carbonate.
The Miami Limestone underlies the entire mainland
portion and Florida Bay within the map area. It is
often covered by a veneer of marl, muck,
and peat. In the northwestern-most part of the
map area, where the Miami Limestone thins, the
Pliocene Tamiami Formation may be exposed below
water level in streams and rivers.
Carbonate sediments of the Miami Limestone
occur within a few meters of the surface throughout
the map area. Limestone is exposed in the Pinelands,
in the northeastern portion of the map area, and may
be more than three meters below land surface at the
coast. The carbonate sediments have been
extensively affected by limestone dissolution,
creating a micro-karstic landscape in the areas where
the Miami Limestone is at the surface or covered by a
thin sediment layer. The dissolutional holes in the
limestones, which are commonly filled with water,
accumulate organic matter and marl. The karstified
surface typically displays up to one meter of relief.
The micro-karstic surface is frequently exposed in
areas mapped as Miami Limestone with thin soils, as
shown on the Surficial Sediments Map. This
irregular surface probably underlies the entire map
area, though it is generally masked by surficial
sediments and soil.
The deepest cores examined for this investigation
penetrated over 50 meters of Neogene and
Quaternary sediments. The majority of the cores
penetrated less than 20 meters of the stratigraphic
section. The oldest units encountered were the
Pliocene Tamiami Formation and the laterally
equivalent portion of an unnamed Pliocene
siliciclastic unit. The Pleistocene Fort Thompson
Formation disconformably overlies the Tamiami
Formation except where the Fort Thompson is absent
and the Miami Limestone lies disconformably on the
Tamiami. The Fort Thompson Formation is
disconformably to conformably overlain by the
Pleistocene Miami Limestone. The base of the
Miami Limestone and the top of the Fort Thompson
Formation may be time equivalent. Holocene marls,
mucks, and peats often overlie the Miami Limestone
within the map area. The relationships of these
stratigraphic units can be seen on cross sections A-A'
through C-C' accompanying the maps.


The Tamiami Formation, as recognized in this
area, consists of very fine to medium-grained,
variably silty and clayey, unconsolidated to poorly
consolidated, variably fossiliferous quartz sand.
Minor amounts of coarse quartz sand were
encountered. A moderately to well indurated, U'
variably sandy limestone (wackestone to packstone)
frequently lies on top of the sand facies and is -
included in the Tamiami Formation. The Tamiami 2520'-I
Formation appears to grade laterally and downward
into an unnamed Pliocene siliciclastic unit. The
siliciclastic unit is not separated from the Tamiami
Formation in this study since the cores did not
penetrate deep enough to properly identify the
formational break.
The Fort Thompson Formation disconformably
overlies the Tamiami Formation in the map area.
The Fort Thompson Formation consists of variably
sandy (quartz), molluscan-moldic limestone
(mudstone to packstone). There is a thin limestone o
(mudstone to wackestone) unit present near the topU
of the Fort Thompson in many of the cores I-
investigated for this study. This limestone is of
freshwater origin. The carbonate sediments above
the Tamiami Formation limestone and below the
Miami Limestone are placed in the Fort Thompson
Formation following the convention of previous
authors (see Causaras, 1986). By following this
convention, sediments that may contain a
Caloosahatchee and/or Bermont fauna are placed in
the Fort Thompson Formation. The Fort Thompson
Formation thins to the northwest within the study
area and is absent in the northwestern-most portion
of the Homestead quadrangle. +
The Miami Limestone varies from a wackestone
to a grainstone and is composed of pellets, skeletal
grains, ooids and carbonate mud with a variable, but
generally minor, quartz sand component. The Miami
Limestone is variably fossiliferous containing
mollusks, bryozoans, foraminifera, and corals. Often
the fossils have been dissolved, creating a very
permeable limestone which comprises the Biscayne
aquifer of the surficial aquifer system. Induration
varies from poor to good and the limestones are
frequently highly recrystallized. Hoffmeister et al.,
(1967) recognized two distinct facies within the
Miami Limestone an oolitic facies and a bryozoan -
facies. Johnson (1992) recognized six facies within
the Miami Limestone ranging from an ooid
calcarenite to a microsparry-coralline limestone.
Based on the available data, the Miami Limestone
was not subdivided, and was mapped as a single
lithostratigraphic unit for this study.

SURFICIAL SEDIMENTS OF THE WESTERN PORTION OF

The Miami Limestone, which forms the bedrock
of the western portion of the Homestead quadrangle,
is generally covered by 15 centimeters to more than
three meters of marl, muck, peat, carbonate mud and
soils. Data utilized in developing this map included
information from Leighty and Henderson (1958),
auger samples, push probes, vibracores, cuttings, and
cores. Craighead (1971) was particularly useful in
helping to delineate different sediment types throughout
the map area.
The area mapped as thin soil over Miami
Limestone covers much of the area of the Everglades
National Park known as the Pinelands, in the
northeastern corner of the map. The surface of the
Miami Limestone in this region is quite irregular due
to micro-karst development. The Miami Limestone
is often exposed in this area. Where limestone is not
exposed, up to approximately 30 centimeters of
sediment may be present.
Surrounding the areas where Miami Limestone is
covered by a thin layer of sediment, a marl of variable
thickness, ranging from less than 30 centimeters to
more than one meter, lies on the limestone. The
marl, which is of fresh water origin, grades laterally
into peats and mucks (organic-rich sediments with
variable clay and carbonate contents) to the south and
west.
South of Mahogany Hammock, marl underlain by
peat occurs between the areas mapped as marl and
those areas mapped as muck. This area was
delineated from the 1958 soils map (Leighty and
Henderson, 1958) and from Craighead (1971). There
is also an area of marl underlain by peat north and
west of the Pa-Hay-Okee Lookout Tower in the
north-central part of the map area. Limestone
underlies this map unit at depths exceeding 30
centimeters.
Muck lies on the Miami Limestone along the
coast and inland along many of the drainage areas;
mangroves commonly grow in this area. The muck
contains varying percentages of organic matter,
carbonate mud and marl, and minor siliciclastic
components. The contact between the muck and the
carbonate mud is based on Leighty and Henderson,
(1958), Craighead (1971), and USGS 7.5 minute
orthophoto quadrangles.
In the northwestern part of the study area,
there is a unit mapped as peat with marl. This unit,
which occurs within the Shark Valley Slough, is
comprised predominantly of mangrove and sawgrass
peat with minor marl beds (Craighead, 1971). The
peat is highly variable in thickness, ranging from a
few centimeters north of Pa-Hay-Okee Lookout
Tower, to over 4 meters in the western part of the
study area. The contact between the peat and the
muck in the vicinity of the Watson River is
speculative and is based on limited data.
Carbonate mud forms the islands within Florida
Bay. There is an area of carbonate mud mapped
along the southern edge of the mainland in the study
area. The mud forms an embankment which is from
one to two feet higher than the surrounding muck and
marl. Craighead (1971) stated that this embankment
is derived from Florida Bay mud which has been
deposited by storms. In the southeastern part of
the map area, this has been called the Buttonwood
embankment, whereas in the southwestern part of the
study area, the mud forms the Flamingo embankment
(Craighead, 1971). Probe data indicates that these
carbonate muds may exceed three meters in
thickness. The surface of the exposed carbonate
muds are often vegetated by abundant mangroves. A
muck component may also be present in these areas.
