This horizon is heavy loam or light clay loam with estimated 22 to 30 percent clay. BC horizon has 2.5YR or 5YR hue, value of 4 or 5 dry and 3 or 4 moist. Auzqui, Babb, Bynum, Dewville, Redcloud, Thayne, Tilton and Wrenman soils are calcareous within 40 inch depths. Auzqui and Tilton soils also lack cambic horizons. Emerald soils do not have cambic horizons and the rock fragments are dominantly stones.
Irondyke soils have xeric moisture regimes and the upper part is influenced by volcanic ash.
F. Mean annual summer soil temperature is less than 56 degrees F., without 0 horizons. Teton and Wrenman soils have bedrock at less than 40 inch depths. Uhl soils do not have cambic horizons and less than 5 percent rock fragments. Tampico soils are on steep mountainside slopes, nearly level floors of narrow valleys, toeslopes and fans in the uplands of elevations of 7,500 to 9,800 feet. Slopes range from 0 to 50 percent.
