Geoarchaeology<br />

The earliest inhabitants <strong>of</strong> <strong>the</strong> Florida Panh<strong>and</strong>le were nomadic hunters pursuing <strong>the</strong> last<br />

<strong>of</strong> <strong>the</strong> Pleistocene megafauna (Braley, 1982). With <strong>the</strong> extinction <strong>of</strong> big game by about 8,000 yr<br />

B.P., <strong>the</strong> paleoindian diet shifted to plants, small animals <strong>and</strong> seafood (Braley, 1982). Sea-level<br />

changes have influenced <strong>the</strong> location <strong>of</strong> <strong>the</strong> Apalachicola River’s delta migration, <strong>and</strong><br />

progradation <strong>of</strong> <strong>the</strong> delta has in turn affected human settlement patterns (Donoghue <strong>and</strong> White,<br />

1995). Figure 2.4 illustrates this phenomenon. The distribution <strong>of</strong> archaeological sites is<br />

consistent with geological studies <strong>of</strong> sea-level history (Donoghue <strong>and</strong> White, 1995). Several <strong>of</strong><br />

<strong>the</strong>se early sites have been drowned by sea level rise. St. Vincent Isl<strong>and</strong> has a long history <strong>of</strong><br />

human occupation.<br />

There are 17 prehistoric sites on St. Vincent Isl<strong>and</strong> (Braley, 1982). One <strong>of</strong> <strong>the</strong>se sites is<br />

<strong>the</strong> Paradise Point Site (Florida State site number 8FR71). This is a stratified midden located on<br />

<strong>the</strong> north shore <strong>of</strong> St. Vincent Isl<strong>and</strong> (2.4 km northwest <strong>of</strong> St. Vincent Point, which is <strong>the</strong> eastern<br />

tip <strong>of</strong> <strong>the</strong> isl<strong>and</strong>) (Braley, 1982, Walker et al., 1995). The midden indicates two periods <strong>of</strong><br />

occupation. The earliest occupation has been radiocarbon dated at 240 A.D. (1,710 +/- 60 years<br />

B.P.), although that date may be in error (Braley, 1982). This occupation was terminated by<br />

rising sea level <strong>and</strong> ab<strong>and</strong>oned for several hundred years. After sea level fell, <strong>the</strong> site was<br />

reoccupied (900-1,100 A.D.). Evidence suggests that <strong>the</strong> Paradise Point site was occupied<br />

during <strong>the</strong> warmer months. In addition to <strong>the</strong> Paradise Point site, archaeological evidence from<br />

midden sites on <strong>the</strong> north side <strong>of</strong> St. Vincent Isl<strong>and</strong> reveal that <strong>the</strong> earliest occupation <strong>of</strong> <strong>the</strong><br />

isl<strong>and</strong> began during <strong>the</strong> Norwood Period, around 4,000 years B.P. Figure 2.5 shows <strong>the</strong> location<br />

<strong>of</strong> archaeological sites on St. Vincent Isl<strong>and</strong> that have been assigned archaeological ages.<br />

St. Vincent Isl<strong>and</strong> was selected as <strong>the</strong> focus <strong>of</strong> this investigation in part because it has not<br />

been studied in great detail in <strong>the</strong> past <strong>and</strong>, more importantly, because it contains a long term<br />

record <strong>of</strong> coastal <strong>evolution</strong> that is undisturbed, well-preserved <strong>and</strong> nearly continuous. The ridge<br />

complex on St. Vincent Isl<strong>and</strong> carries a record <strong>of</strong> changing sediment sources <strong>and</strong> changing<br />

oceanographic conditions over at least <strong>the</strong> past four millennia (Stapor 1973, 1975). Ano<strong>the</strong>r<br />

important factor in <strong>the</strong> selection <strong>of</strong> this site was <strong>the</strong> physical character <strong>of</strong> <strong>the</strong> isl<strong>and</strong>. The narrow<br />

geographic limits <strong>of</strong> <strong>the</strong> isl<strong>and</strong> <strong>and</strong> <strong>the</strong> regional tectonic stability <strong>of</strong> northwest Florida make it<br />

possible to collect hundreds <strong>of</strong> data points representing past sea level st<strong>and</strong>s without concern for<br />
