Council soils have finer textured, more acid C horizons. Dryden soils have mottles of low chroma in the lower part of the argillic horizon. Eleva soils have a paralithic contact at depths between 20 and 40 inches.
Lamont soils are more acid and are coarser textured in the lower C horizon.
Mecan soils have thicker sola. Wyocena soils have less silt and clay in their sola and have loamy sand C horizons. Kidder and Miami soils are fine-loamy. Locke soils have dark colored surface horizons and mottles of low chroma within the upper 10 inches of the argillic horizon. Spinks soils are sandy.
