Fort Valley Plateau District

An anomalous area within the Fall Line Hills is known as the Fort Valley Plateau. It is characterized by flat-topped interfluves with narrow, 50-150 feet deep, steep-walled valleys. This area is distinct from the Fall Line Hills in that the broad, flat-topped interfluves are the dominant feature, there are fewer streams, and there is less local relief. The area is less dissected than the Fall Line Hills because it is underlain by the more clayey units of undifferentiated Eocene, Paleocene and possible Cretaceous age sediments. Elevations range from 500 fee in the north to 250 feet in the southeast, indicating a southeast regional dip. The east and west boundaries are the Ocmulgee and Flint River Valleys, respectively. The southern boundary is formed by Hogcrawl and Big Indian Creeks. The northern boundary occurs at approximately the 500 foot elevation where the narrow, steep interfluves of the Fall Line hills abruptly change to the lower, flat-topped interfluves of the Fort Valley Plateau.
