The South Georgia area’s ten counties vary in size from Lanier’s 200 square miles to Lowndes’ 511 square miles and as an aggregate total 3495.7 square miles. A land area almost the size of Delaware and Rhode Island combined (3,627 square miles) or Puerto Rico (3,508 square miles) but only six percent of Georgia’s 58,977 square miles. Geographically, the area is located in the Coastal Plains region of the state. The Coastal Plains region occupies the two-thirds of the state below the "fall line" or sometimes called the "gnat line." The fall line is a change in geography that occurs along a line that runs roughly from Columbus, to Macon and then to Augusta. The region is also characterized by wetlands to the southeast, and for the most part, gently rolling hills and level plains. The elevation ranges from a high in Turner County of 480 feet to a low in Echols County of 75 feet above sea level. Two major stream systems, the Withlacoochee River and the Alapaha, both part of the Suwannee River Basin, drain the area. Water is a positive asset and resource to the area, from the Floridian aquifer – a resource for agriculture, industry, and people – to its many lime sink lakes and ponds, bounding with bass, bream, and waterfowl. The South Georgia area is heavily forested – predominately long leaf, loblolly and slash pine – and also has a large areadevoted to farming. The area’s fertile soils, mostly Tifton Sandy loam and Norfolk sandy loam, grow tobacco, cotton, peanuts, peaches and many other crops. (64% or the region is forested, while 23% is devoted to agriculture.) South Georgia’s Florida-like humidity and mild temperatures allow the growth of Spanish moss, great Live Oak trees, and other plants.
