Summary

Underwater exploration and excavation of target loci along the inundated Paleo-Suwannee River Channel has recently focused on the Brownstone site. The western edge of the paleo-channel in the study area contains several grades of cryptocrystalline chert and dolomite. Materials recovered and attempts to access underlying stratified deposits are detailed. Further, correlation of the inundated Pleistocene landscape and known riverine features with timing of human occupation and utilization of adjacent terrestrial areas has led to some novel insights regarding the early occupation of Florida. Recent observations of storm driven, and sea level rise, salt water incursions in the GOM are discussed within the context of the ever shrinking, now submerged Pleistocene landscape.
