MLRA 60A - Pierre Shale Plains and Badlands Nebraska, South Dakota, and Wyoming 23,600 km2 (9,110 mi2)

Soils:
Most of the soils are Orthids. They are moderately deep and deep and fine textured and have a mesic temperature regime and montmorillonitic mineralogy. Nearly level to moderately sloping Camborthids (Kyle, Pierre, Swanboy, and Winler series) are on shale uplands. Shallow Torriorthents (Ennings, Lismas, Midway, and Samsil series) are on steeper slopes. Nearly level to gently undulating, deep and moderately deep, medium textured Argiustolls (Manter, Nunn, Satantz, Tuthill, Keith, and Richfield series) are on terraces and uplands. Shallow Torriorthents (Epping, Imlay, and Orella series) and Camborthids (Bufton and Conata series) are in the Badlands. Torrifluvents (Glenberg, Haverson, and Lohmiller series) are on the bottom land of major streams.
