Introduction\

The Pleistocene epoch existed during the Sangamon interglacial period that was about 150,000 years ago. There was global warming when the sample was collected and the beach elevation was 2m above sea level, which is during the Pamlico barrier and Princess Anne barrier. Some marine bed samples were collected from the Forest City Gun and Rod Club, Savannah, GA in 120,000 years ago.

Abstract

The Atlantic coastal plain in Southeastern Georgia has been the subject of the numerous investigations but no detailed mapping. This part of Southeastern Atlantic Coastal Plain is in the structural low known as the Southern Georgia Embayment and is characterized by numerous costal barrier islands and intervening marshes.Markewich et al. (1992) described the emergent Pliocene and Pleistocene sediments as being predominantly fossil-poor, transgressive, regressive, or prograding barrier sand.
