Summary:
Alum Bluff Group referred to as undifferentiated in this report. Because formations assigned by previous workers were differentiated on the basis of micro- and macrofossil faunas and implied age, not lithology, and do not satisfy the requirements of the Code, they are not used by this author. Alum Bluff is described in several outcrops and includes sediments differentiated as Chipola, Shoal River, Oak Grove, Whites Creek, Choctawhatchee, Red Bay, and Yellow River by others. Outcrop 10, at Red Bay, Walton Co., was previously referred to as the Choctawhatchee, the middle unit of the Alum Bluff by Matson and Clapp (1909). This outcrop of undifferentiated Alum Bluff was also considered to be the type locality of the "short lived" Red Bay Formation of Choctawhatchee age by Puri and Vernon (1964).
