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. These will likely be proposed as new series when the subset surveys with these phases are updated.
