An area in the southeastern part of the State, lying to the south and southeast of the black belt, and including part of Bullock, Lowndes and Montgomery Counties. The area contains approximately 2,300 square miles. The line of division between the black belt, or prairie section, and the Chunnennuggee Ridge, or blue marl section, is marked by a rather abrupt ascent, amounting almost to an escarpment, 100 feet or more in height. This escarpment or ridge is most conspicuous and most typical in the vicinity of Union Springs, and it was here that the name by which the entire ridge has come to be known was first bestowed. Geologically the area belongs to the Cretaceous, but the soils appear to have been derived mainly from the Lafayette formation. In places the soils are quite sandy. As a whole, they are of average fertility and adapted to the cultivation of most of the staple and pasturage crops. The eastern portion of the region is quite rolling, at times approaching ruggedness. The country is well drained, having numerous small streams, most of which flow between bluffs of considerable height. About one-half of the section is covered with forests, but the trees are mainly of second growth. The most common varieties are short-leaf pine, sweet gum, willow, bay, spruce pine, water oak, red oak, and cottonwood. Agriculturally the Chunnennuggee Ridge area has always been well advanced. The first local agricultural society in the State was organized within its bounds, and was called the Chunnennuggee Horticultural Society.
