Berzatic soils have 15 to 35 percent calcium carbonate equivalent in the particle-size control section. Blacktop soils are intermittently moist in the upper part of the moisture control section for about 10 days cumulative in the period June through September by convection storms. Cadrina soils have fragments of sandstone or shale in the particle-size control section and are intermittently moist in the moisture control section during summer months. Pintwater and Walknolls soils have horizons with identifiable secondary carbonates. Sojur soils have 18 to 25 percent clay in the particle-size control section and are dominated by channers.
Singatse soils are on hills and mountains.
They formed in residuum and colluvium derived from volcanic or mixed rocks. Slopes are 8 to 75 percent. Elevations are 4,000 to 6,500 feet. The climate is cool-arid with cool, moist winters and hot, dry summers. The mean annual precipitation is 4 to 8 inches, the mean annual temperature is 46 to 51 degrees F., and the frost-free period is 100 to 130 days.
