MAPPING UNIT 3CE - RHONE LOAM <br />' S TO 30 PERCENT SLOPES <br />This deep, well-drained, gently sloping to steep soil is on moun- <br />tainsides and ridges between 7600 to 8600 feet elevation. This <br />soil formed in residuum from sandstone and marlstone. The average <br />annual precipitation is about 20 inches, the average air temperature <br />is about 40 degrees F., and the average frost-free period is less <br />than 75 days. <br />Typically, the upper part of the surface layer is brown loam about <br />8 inches thick, and the lower part is brown sandy clay loam 20 <br />inches thick. Sandstone is at a depth of 52 inches. <br />The permeability and available water capacity are moderate. The <br />effective rooting depth is 40 to 60 inches. Surface runoff is <br />slow, and the erosion hazard is slight. The capability subclass <br />• is VIe, non-irrigated. <br />CLASSIFICATION OF MAJOR COMPONENTS <br />Rhone loam, 5 to 30 percent slopes; Fine-loamy, Mixed Pachic <br />Cryoborolls. <br />INCLUSIONS <br />Included with this soil in mapping are small areas of Parachute <br />and Northwater soils. The moderately deep Parachute soils are <br />on smooth ridge crests and west and south-facing side slopes, <br />The Northwater soils are on north-facing side slopes. These areas <br />make up about 10 to 15 percent of the map unit, <br /> <br />I-5 <br />
