Comments: The archaeological investigations at the Castillo de San Marcos were in response to a request by the Superintendent, Gordy Wilson, to monitor the installation of an underground electrical line. The line extended from a telephone pole on San Marco Avenue to an electrical conduit box on the west side of a new addition to the administrative offices. The addition will house the fort's archive and library collections. The ensuing trench measured approximately 90 ft long (east-west) by 1.5 ft wide. The depth ranged from 22 to 28 inches below ground surface.
Except for a probable road bed along the western portion of the trench, no archaeological features were documented during monitoring. Most of the ground penetrating disturbance was limited to recent fill deposits associated either with 19th or 20th century activities around the fort. These fill deposits consisted of various soil types ranging from gray to reddish sands or brown sandy-loam. Only toward the west end of the trench were brown colored sands encountered beneath the fill deposits that may have been associated with colonial activities. Beneath this narrow layer of brown sand was the sterile yellow sand. Inspection of the trench bottom did not reveal any cultural features which could have extended into the sterile substratum, however.
The only possible feature encountered was the remanent to a probable road bed found toward the west end of the trench in the fill deposits. The remanent consisted of oyster shell mixed with course gravels and sands and was probably part of the 19th to 20th century road known that is now San Marco Avenue.
The artifacts found primarily date from the late 19th to 20th centuries. Recovered were one granite ware fragment, one ginger beer bottle fragment, and one aqua-green electrical transformer fragment. In addition, one unidentifiable (UID) majolica fragment and a large mammal leg bone fragment were also found. The artifacts were recovered while inspecting the back dirt piles associated with the trench.
Because of the nature -of the soil deposits observed during monitoring (that is, it was fill deposited within the last 50 to 100 years), no additional archaeological investigation was required. -As such, clearance was given for construction activities occurring under BDAC 94-0445.
