These are the Beadle , Carlson , Harney , Kirley , McClure , Mento , Peno , Raber , and Spearville soils in the same family. Beadle, Peno, and Raber soils have clay loam or clay argillic horizons and formed in glacial till. Kirley soils contain more sand in the series control section and formed in alluvium. McClure soils have contrasting clayey substrata between depths of 20 and 40 inches. Reliance soils are on nearly level to strongly sloping uplands and terraces.
Surfaces are plane or slightly convex.
Slope gradients typically are less than 6 percent, but range from 0 to 15 percent. They typically formed in loess and silty materials of mixed origin with contrasting substrata typically below depths of 5 to 10 feet, but ranging to as shallow as 40 inches. The mean annual temperature ranges from 45 to 50 degrees F. and mean annual precipitation ranges from 15 to 24 inches. These are the competing McClure soils and the Agar , DeGrey , Hoven , Lowry , Millboro , Onita , Promise and Scott soils. Agar and McClure soils are in similar nearby landscapes.
