<br />MAPPING UNIT DESCRIPTION <br />Delta-Montrose Survey Area Ru <br />Mapping Unit: Rough broken land. <br />Position: Steeply sloping sides of mesas. <br />Drainage: Well drained. <br />Slope: 10 to 60 percent. <br />Sail Profile: Texture Thickness Permeabili <br />Surface: 1/ Variable 2/ --- 2/---- <br />Underlying Material: <br />J Variable <br />1/ Consists of exposures of sedimentary shale and sandstone, gravelly <br />alluvial material, colluv%al debris: and shallow soils. Midway on <br />the slopes almost barren exposures of sedimentary shale and sand- <br />stone. <br />2/ No estimates were made. <br />Erosion Hazard: Moderate from wind and water. <br />Capability Unit: VIIs Non-Irrigated. <br />Range Site: Salt desert breaks <br />Other Features: <br />Not suitable for cultivation. <br />The vegetation is a sparce covering of native grasses, sage, cactus, <br />brush and annual weeds. <br />Severe limitations for home sites because of steep slopes, high shrink- <br />swell potential, low permeability in certain areas, the shale and sand- <br />stone and the unstable slope conditions. <br />Sui tabi 1 i ty for: <br />Dikes, diverision Poor, shallow and stony. <br />Reservoir Area Unsuitable, shallow to sandstone or shale, steep slopes. <br />Embankment Shallow, and stony. <br />Irrigation Unsuitable, stony, steep and sfiallow. <br />
