Dekalb and Ramsey soils lack argillic horizons. Gilpin soils have bedrock at depths of less than 40 inches. Muse soils are clayey, and Whitley soils are fine-silty. Shelocta soils have mixed mineralogy. Well drained with rapid or medium runoff, depending on slope.
Permeability is moderately rapid.
Most areas are in forest but less steep areas are used mainly for pasture and crops. The forest vegetation is chiefly yellow-poplar, upland oaks, Virginia and shortleaf pine, hickory, and laurel. The series is extensive. Jefferson series formerly included Paleudults. Lab data of representative pedon reveal silt loam texture in the A and E horizons.
