Farland, Hanaker and Xavier soils do not have soft bedrock at depths of less than 40 inches. Jekley soils have a lithic contact at a depth of 20 to 40 inches. Morton soils are on level to rolling plains. Slope gradient is commonly 0 to 6 percent, but it ranges to 15 percent. The soils formed in material weathered from soft calcareous silty shales, siltstones, mudstones, and fine grained sandstones.
Some areas have a thin glacial till mantle.
Mean annual air temperature is 39 to 45 degrees F, and mean annual precipitation is 12 to 20 inches. Most of the precipitation comes in the spring and summer. These are the competing Farland soils and the Arnegard , Belfield , Flasher , Grail , Regent , Rhoades , Savage , Vebar , Werner and Williams soils. The Farland and Savage soils are mainly in the stream valleys and on foot slopes. Savage soils are fine and do not have soft bedrock within depths of 40 inches.
