Excerpt from A Report on the Limestones and Marls of the Coastal Plain of Georgia The region is a comparatively low plain sloping gently to the southeast. The highest elevations are along the Fall Line where they vary from 500 to 700 feet above sea level. A Slope of 3 or 4 feet per mile is general from this line to the Atlantic Coast. Although, when compared with the topography of those areas north of the Fall Line, the surface relief is slight it is not without distinctive features. The most notable topographic feature is that belt along the Fall Line known as the Fall Line Hills. This belt extends entirely across the State with a width varying from 30 to 40 miles, with the Fall Line the northern boundary. This area has a maximum relief of about 350 feet, considering the larger streams as the base, which shows a much more mature topography than the portion of the plain to the south. Cretaceous sands and clays, the principal materials underly ing the area, are easily eroded and have caused deep gullies and washes throughout the belt. To the north the Fall Line Hills merge into the Crystalline area and to the south into the Dougherty Plain, another distinctive topographic feature of the Coastal Plain.
