Washington Slope District

The Washington Slope District is characterized by a gently undulating surface which descends gradually from about the 700 foot elevation at its northern margin to about the 500 foot elevation at its southern edge. Streams occupy broad, shallow valleys with long, gentle side slopes separated by broad, rounded divides. Relief throughout this district is 50-100 feet except in the vicinity of the Ocmulgee River, which flows in a steep-walled valley 150-200 feet below the adjacent area. The western boundary corresponds to the drainage divide between the Atlantic Ocean and the Gulf of Mexico. The southern boundary, known as the Fall Line, follows the contact between the metamorphic rocks of the Piedmont and the sediments of the Coastal Plain.
