The less permeable, moderately well drained Miami and well drained Russell soils are on summits, shoulders and backslopes of dissected till plains. The well drained, more silty Rush soils are on similar landforms as the Ockley soils. The somewhat poorly drained Sleeth soils are on level summits of outwash plains. The poorly drained and very poorly drained Westland soils are in depressions on outwash plains and stream terraces. The potential for surface runoff is negligible to high.
Permeability is moderate in the solum and very rapid in the substratum.
Most areas of these soils are used to grow corn, soybeans, wheat and hay. Native vegetation is dominantly mixed hardwood forest. Central and southeastern Indiana, central and northern Illinois, southwestern Michigan, central and southern Ohio, and southern Wisconsin. Carroll County, Indiana, 1955. Till substratum, sandy substratum, and bedrock substratum phases are recognized.
