Summary:

Gulfport Formation is limited to a 1- to 3-km-wide discontinuous barrier ridge belt that borders the Gulf mainland shore. Commonly overlies Prairie Formation (alluvium) landward and Biloxi Formation (shelf deposits) near shore. Grades upward from poorly to moderately sorted shoreface sands to foreshore sand and dunes. Fig. 1 shows unit extending from Gulfport, MS, eastward to the mouth of the Ochlockonee River, Franklin Co., FL. Deposited during the Sangamonian.
