• medium to high, runoff is medium to rapid, and the erosion hazard is high. The vegetation types are <br />sagebrush-grassland and mountain shrubland. <br />In a typical profile, the topsoil is loam, clay loam, silty clay loam, or gravelly clay 6 to 12 inches thick. <br />The subsoil is sandy clay loam, silty clay, clay loam, or clay 28 to 40 inches thick. The substratum <br />consists of clay, gravelly clay, very gravelly sandy clay, channery clay, or clay loam 7 to 20 inches thick. <br />Depth to bedrock ranges from 40 to 60 inches. <br />JBC - Jerrv-Barnette Loams, 15-30 % slopes have approximately 12 inches of salvageable soil. <br />Excessive clay, slope, depth to bedrock, and excessive gravel in the substratum may limit salvage in some <br />areas. <br />These are deep soils which have developed in colluvium and residuum derived from shale. They are <br />found on moderately steep mountain sideslopes at elevations ranging from 7400 to 8300 feet. They are <br />well-drained soils with slow to moderate permeability. Available water holding capacity is medium to <br />high, runoff is medium to rapid, and the erosion hazard is high to very high. The vegetation types are <br />sagebrush-grassland and mountain shrubland. <br />A typical profile is the same as for Jerry-Barnette Loams, 5 to 15 percent slopes. <br />NB -Nihill channery Loams, 8-45% sloRes generally have no salvageable soil because of steep slopes <br />make salvage impractical. <br />• These are deep soils that occur only on the fans on the valley floors, generally below Torriortltent-Rock <br />outcrops. They consist of Nihill channery loam on gently sloping to steep fans adjacent to the valley <br />floors. It is composed primarily of Nihill channery loam with inclusions of Torrifluvents. The erosion <br />hazard is moderate to very high, runoff is medium, and the flooding hazard is rare. The dominant <br />vegetation type is sagebrush and grassland. The present land use is range and pasture and the range site is <br />salt desert breaks. <br />In a typical profile, the topsoil is loam, gravel loam, very channery gravel loam 3 to 9 inches thick. The <br />subsoil is gravelly clay 10 inches thick. The substratum consists of loam and clay loam ]0 to 16 inches <br />thick. Depth to bedrock ranges from 40 to 60 inches. <br />NBD - Northwater-Barnette Loams, 25-50% slopes generally have no salvageable soil because of steep <br />slopes make salvage impractical. <br />This is a very deep soil that consists of Northwater loam and Barnette loam on moderately steep to steep <br />north facing mountain sideslopes. It is primarily composed of Northwater and Barnette loams with <br />inclusions of Nagisty, Rhone, and other soils. The erosion hazard is moderate to very high, runoff is <br />medium, and the flooding hazard is none. The vegetation type is dense mountain shrubland. The present <br />land use is range and wildlife habitat and the range site is brushy loam. <br />In a typical profile, the topsoil is loam and sandy loam 6 to 18 inches thick. The subsoil is sandy loam 28 <br />inches thick. The substratum consists of loam and sandy loam 10 to 16 inches thick. Depth to bedrock <br />ranges from 40 to 60 inches. <br />• RB -Rhone Loam, 2-20 % slopes has approximately 42 inches of salvageable soil. In some areas, the <br />salvage thickness may be less because of excessive charmers at depth. <br />Revision Date: 11/30/06 <br />Revision Number: PR-02 <br />
