MLRA 90 - Central Wisconsin and Minnesota Thin Loess and Till Minnesota and Wisconsin 55,750 km2 (21,530mi2)

Soils:
Most of the soils are Boralfs. They are moderately deep to deep and medium textured and have a frigid temperature regime and mixed mineralogy. Well drained and moderately well drained, nearly level to moderately sloping Glossoboralfs (Santiago, Otterholt, Spencer, and Antigo series), somewhat poorly drained, nearly level to moderately sloping Glossaqualfs (Almena and Withee series), and nearly level to moderately sloping Ochraqualfs (Freer series) in loess-mantled drift are on outwash and till plains. Ochraqualfs (Marshfield series), Glossaqualfs (Auburndale series), Haplaquepts (Cable and Rib series) and Haplaquolls (Adolph series) are the lower Iying wet mineral soils. Borosaprists (Seeleyville and Lupton series) and Borohemists (Rifle and Greenwood series) in the deeper depressions formed in organic residue from plants. Udipsamments (Plainfield, Menahga, and Friendship series) are on the sandy outwash plains. Udifluvents are on the flood plains of rivers and streams.
