Malcolm and Mendota soils are less than 40 inches to the base of soil development. Meadowbrook soils have carbonates at depths greater than 60 inches. Osco and Elkhart soils average less than 15 percent sand throughout the series control section. Sibley soils have a mollic epipedon greater than 24 inches thick. Bowes soils do not have a mollic epipedon.
Waupecan soils are on nearly level to gently sloping glacial outwash plains and stream terraces.
Slope gradients range from 0 to 5 percent. Waupecan soils formed in loess or other silty material 24 to 48 inches in thickness and in the underlying sandy and gravelly outwash sediments. These are the competing Bowes and Plano soils and the Batavia , Drummer , Elburn , Longlois , Troxel , Warsaw , and Wea soils. The Bowes, Batavia, and Longlois soils are closer to drainageways on similar parts of the landscape. Batavia and Longlois soils, like Bowes, have a dark colored surface layer less than 10 inches in thickness.
