In addition, McClure soils have contrasting clayey 2C horizons and the Mento soils have 5 to 15 percent sodium in the B and C horizons. Peno soils have thinner sola and have calcium carbonate at shallower depths. Raber soils have thinner A horizons and are drier. Beadle soils are nearly level to sloping hills of uplands. Slope gradients typically are 0 to 6 percent and range from 0 to 9 percent.
Surfaces are smooth, plane, or convex.
These soils formed in clay loam glacial till. The mean annual air temperature ranges from 45 to 52 degrees F, and the mean annual precipitation ranges from 17 to 26 inches. These are the Dudley , Houdek , Jerauld , Prosper , Stickney , and Tetonka soils. The Dudley, Jerauld, and Stickney soils have natric horizons and are on nearly level, plane to slightly concave surfaces and are in slightly lower positions. Tetonka soils are in depressions and have E horizons.
