They formed in residuum <br />and sediments weathered from interbedded shale and arkosic sandstone. <br />Elevation is about 5000 to 6800 feet- Avers Re annual precipitation is <br />about 1L to 17 incises. Mean annual air temperature is about A7°F. Bresser <br />soils are about 50 percent of the unit and Cushman soils are about 25 <br />-- percent. Included in Tapping and making up about 25~ of the unit are small <br />i <br />-- areas of sandstone outcrop, Truckt.on, Ascalon, Kutch, Renohill, Wiley <br />and Yaca soils. <br />Typically Eresser soils have a grayish brown s~irface layer about <br />~'~+.,. 7 inches thick.
