Typically, the surfacTayer is grayish brown light clay loam about 2 inc~thick. The subsoil is grayish brown <br />and light yellowish brown clay about 16 inches thick. It overlies shale bedrock at a depth of l8 inches. Petmeabiliry <br />is slow, and the available water capacity is low. Surface runoff is rapid. The hazard of wind erosion is slight, and the <br />hazard of water erosion is high. <br />Most of the acreage is rangeland that is also used for recreation and wildlife. A cold climate and a short <br />growing season limit the production of introduced grasses and preclude use of this soil as cropland. <br />Management of this soil for range should include a deferred grazing system and brush control. Grasses <br />recommended for seeding include western wheatgrass and bluebunch wheatgrass. The dominant native vegetation <br />consists of wheatgrasses, Indian ricegrass, squirteltail, winterfat, and big sagebrush. The total annual production <br />averages 500 pounds of air-dry forage per acre. <br />Slope and shallow depth to bedrock are the most limiting soil properties to be considered in the design of access <br />roads and recreation homesite subdivisions. A shallow depth to bedrock makes excavation of access roads and <br />foundations for buildings difficult. Slope stabilization is difficult even where homes are constructed on nearly level <br />pads. Surface runoff resulting from snowmelt increases the erosion hazard on cut and fill slopes. Seeding of vegetation <br />minimizes the erosion hazard, but establishing a stand is difficult. Homes should be designed to utilize existing slopes <br />and keep foundation cuts to a minimum. Roads should be designed to keep cut and fill slopes to a minimum and provide <br />drainage outlets for excessive snowmelt. All-weather asphalt surfaces are impractical unless provisions are made to <br />offset frost action. <br />Rangeland wildlife includes mule deer, sage grouse, white-tailed jackrabbit, ground squirrels, mourning dove, <br />and yellow-bellied marmot.
