The Antigo series consists of very deep well, drained soils which are moderately deep to sandy outwash. These soils formed dominantly in loess or water laid silty deposits but the lower solum typically formed in loamy alluvium or sandy outwash or both. These soils are underlain by stratified sandy outwash. Typically they are on glacial lake plains, moraines, outwash plains and stream terraces.
Permeability is moderate in the silty and loamy layers and rapid or very rapid in the sandy outwash.
Slopes range from 0 to 30 percent. Mean annual precipitation is about 30 inches. Antigo silt loam - on a plane slope of less than 1 percent in a cultivated field at an elevation of about 1520 feet. The depth to stratified sandy outwash ranges from 20 to 40 inches. Thickness of the silty mantle ranges from 12 to 40 inches.
