The 7.5YR hue is usually in the lower part. The Bt horizons are typically loam, clay loam, or sandy clay loam, but some pedons include texture of silt loam or silty clay loam high in content of sand. Reaction ranges from medium acid to very stongly acid. Some pedons have a thin 2BC horizon.

These are the Casco , Fox , Hixton , and Ionia soils in the same family and the similar Burnsville , Sattre , and Wapsie soils. The Casco soils have coarse textured sediments at depth of less than 24 inches. Fox and Ionia soils have carbonates at a shallower depth. Hixton soils are underlain by sandstone. Burnsville soils have an argillic horizon with 10 to 18 percent clay.
