Slickensides range from many in the upper part to few in the lower part of this horizon. These are the Redco and Tahoula series in the same family and the Wiergate series. Redco soils are not calcareous above 40 inches.
Wiergate soils have mollic surface layers.
Burkeville soils are on gently sloping to strongly sloping uplands. Slopes are mainly 3 to 6 percent but range from 1 to 15 percent. Most areas are under active erosion with V-shaped gullies 0.5 to 8 feet deep. These soils formed in weakly consolidated clays and marls of Tertiary age, mainly of the Fleming formation. Mean annual rainfall ranges from 48 to 55 inches and is fairly evenly distributed throughout the year.
