<br />115 - Rock Jutcrop-Moyerson complex, 15 to 40 percent slopes. <br />'this complex occurs on steep sideslopes and ridgetops at intermediate <br />elevations and developed from fine-textured calcareous residuum primarily from <br />shale. It is comprised of about 50 percent rock outcrop and 40 percent Moyerson <br />soils. Small areas of Red creak and Rentsac were included in mapping. Redcreek <br />soils are shallow and loamy. Rentsac soils are shallow and loamy-skeletal. These <br />included soils occupy about 10 percent of the unit. <br />fhe rock outcrop is primarily exposed shale, silts tone and claystone bedrock <br />which is calcareous, brown to yellow and fractured. Included with rock outcrop <br />are very shallow, skeletal soils adjacent to exposed bedrock. <br />The Moyerson soil is shallow, calcareous, and wall-drained. In a typical <br />profile, the surface layer is light yellowish brown about 2 inches thick. 'The <br />• subsurface soil is light yellowish brown channery loam about 5 inches thick. <br />The substratum is pale brown calcareous channery silty clay about 14 inches thick <br />and is underlain with fractured, interbedded sandstone, loamstone, and shale <br />at a depth of 14 inches. <br />The ~4oyerson soil has moderately slow to slow permeability and medium to <br />moderately rapid runoff. The erosion hazard is low to moderate from wind and <br />moderate to high from water. Available waterholding capacity is moderate. <br />Effective rooting depth is 10 to 20 inches. <br />'f his soil is used for livestock grazing and wildlife habitat. The vegetation <br />is primarily mixed perennial grasses, sparse big sagebrush and soma areas of <br />cheatgrass. <br />The average depth of suitable topsoil material is 4 inches. This material <br />• is rated poor to fair with suitability decreasing with depth. <br />
