THE UNDERWATER ARCHAEOLOGY OF PALEOLANDSCAPES, APALACHEE BAY, FLORIDA

Michael K. Faught

Submerged prehistoric sites investigated in northwest Florida along the margins of the drowned channel (or PaleoAucilla) extend our understanding ofprehistoric settlement patterns and paleolandscape utilization. Bifacial and uni- facial tools indicate Late Paleoindian and Early Archaic logistical activities at these sites, as well as later Middle Archaic occupations. Other evidence for terrestrial conditions at these sites include extinct and extant terrestrial faunal remains, in-place tree stumps, and possible eroded middle Holocene shell middens. This report outlines the methodologies used for site investigations, and then discusses the geomorphic setting, character cultural-historical connections, and timing offull inundation for these offshore sites. During late Pleistocene and early Holocene times, the coastline was much farther out on the continental shelf and this segment of the PaleoAucilla was forested and well inland. Later during the middle Holocene stages of transgression, the segment was more of a wide grassy marsh with brackish water tidal creeks and oysters. In this continental shelf setting, submerged archaeological sites remain in clustered arrays accessible by underwater archaeolog- ical methods, and the data provide a critical supplement to ourpresent understanding of late Pleistocene and early Holocene settlement patterns and paleolandscape utilization.

Los sitios prehistdricos sumergidos en la placa continental del Golfo de Mdxico presentados en este articulo han producido hallazgos de restos liticos que se han diagnosticado como pertenecientes a los tiempos culturales Paleoindio (epoca geol6g- ica tardio Pleistocenica) y Arcaico (epoca geolo'gica temprana Holocenica). Estos hallazgos confirman y extienden la ocu- pacidn y el patron de asentiamento prehist6rico del noroeste de la Florida alfin de Pleistocenica, que es ya conocida a traves de excavaciones terrestres en esta drea. Al alejarse de la costa, estos sitios representan ocupaciones mds antiguas y asi aumen- tan nuestro conocimiento de las estrategias de poblacidn y organizacidn de los Paleoindios Clovis y sus descendientes. Final- mente, las investigaciones presentadas en este articulofomentan mayores estudios de la placa continental como sitio potencial de restos prehist6ricos. Esta informacidn enfoca en el desarollo de los principios y metodos basicos necesarios para el estu- dio de los sitios prehistdricos sumergidos en otras areas del mundo.

The image also includes bathymetric contours (isobaths) of the continental shelf offshore at selected 20-m intervals. The 100-m isobath represents the probable extent of the late glacial maximum (LGM) paleofandscape, the 40-m isobath the possible Younger Dryas (YD) shoreline, and the 20-m isobath the possible shoreline at 8000 B.P.
