Koronis and Taopi soils have less gravel in the lower part of the solum. Mohawk soils have dark colors in the solum which are inherited from parent material. Neda soils have the lower part of the solum formed in till with a high content of shale fragments. Oneco soils have redder hue in the lower part of the soils and have the lower portion of the solum formed in residuum from limestone. Racine soils have the lower part of the solum formed in till and have less gravel in the lower part of the solum.
Glenhall soils are on outwash plains and also on till plains which have a layer of outwash.
Slopes are 1 to 4 percent. Glenhall soils formed in up to 20 inches of silty material and the underlying loamy outwash. Mean annual temperature ranges from 50 to 52 degrees F, and mean annual precipitation ranges from 36 to 38 inches. These are the poorly drained Drummer soils, the somewhat poorly drained La Hogue soils, and the moderately well drained Billet and Barce soils. Barce soils have the lower part of the solum formed in till and are on similar landscape positions.
