They range from shallow on the sandstone and shale ridges to very deep in the valleys and on the large limestone formations. The proportion of poorly drained soils, mainly Aquepts and Aquults, is very small. The deeper soils support good oak-hickory stands. The shallower soils, mostly on southern and western slopes, support pine or oak-pine types. Understory vegetation is also reflected by aspect.
Little bluestem is the dominant grass species.
