The somewhat poorly drained Atlas and Coatsburg soils and the well drained Hickory and Ursa soils are downslope. Atlas and Coatsburg soils are shallower to the paleosol and Coatsburg soils have a mollic epipedon. Hickory soils average more than 15 percent sand in the particle-size control section and do not contain a paleosol. Ursa soils average more than 35 percent clay in the particle-size control section. The somewhat poorly drained Blair soils are on similar landform positions but have the major part of their solum formed in water-worked sediments that lie above the till and beneath the Peoria loess.
Elco soils are moderately well drained and are on similar landform positions.
The moderately well drained Winfield, the well drained Rozetta and Fayette soils, and the somewhat poorly drained Keomah soils formed entirely in loess and are upslope on higher backslopes and shoulders or on crests of summits. The somewhat poorly drained Keller soils have a mollic epipedon, are in biosequence with Fishhook soils, and are on similar landform positions. Somewhat poorly drained. The potential for surface runoff is low to medium. Permeability is moderate in the loess and slow in the till.
