These soils formed in sandy alluvium and outwash material of Pleistocene age. The mean annual air temperature ranges from 51 to 54 degrees F. and the mean annual precipitation ranges from 28 to 32 inches. These are the Judson , Olmitz and Pohocco soils. Judson and Olmitz soils have mollic epipedons more than 24 inches thick, have more silt and clay in the control section, and are on foot slopes. Pohocco soils have more silt and clay in the control section, have carbonates at depths of 12 to 40 inches, and are slightly higher on the back slope.
Surface runoff is medium on the strongly sloping areas and rapid on the moderately steep areas.
Permeability is rapid. The series is of limited extent. Saunders County, Nebraska, 1992. The series name is from a prominent peak in the county.
