loam, clay loam, or silty clay loam textures in the particle-size control section. They are <br />neutral to mildly alkaline in the argillic horizon. Theon soils are dominated by pebble <br />sized fragments in the subsoil and are formed in granitic parent material. They have a <br />paralithic contact above the lithic contact. Waucaba soils are dominated by pebble and <br />cobble sized fragments in the argillic horizon and lack a BCk horizon. <br />GEOGRAPHIC SETTING: Valleycity soils occur on the marginal hogbacks and ridges of <br />the Salt Valley anticline, Burro Canyon Formation. Slopes are medium and long in length <br />and range from 8 to 25 percent. The soils are formed in colluvium and residuum and <br />mostly from calcareous sandstones and shale. Mean annual temperature is 52 to 57 <br />degrees F and average annual precipitation is 5 to 8 inches. The freeze-free period is <br />150 to 170 days. <br />GEOGRAPHICALLY ASSOCIATED SOILS: These are the Farb, Monue, and Chipeta <br />soils. Farb soils have a loamy particle-size control section and lack a B horizon. Monue <br />soils lack bedrock above a depth of 40 inches. Chipeta soils are less than 20 inches to <br />paralithic contact. <br />DRAINAGE AND PEREMABILITY: Valleycity soils are well drained, medium runoff; and <br />moderate permeability. <br />USE AND VEGETATION: These soils are used for rangeland; wildlife habitat and for <br />recreation. Potential vegetation includes galleta, shadscale, Indian ricegrass, <br />blackbrush, rabbitbrush, and pricklypear. DISTRIBUTION AND EXTENT: Southeastern <br />Utah. The soils of this series are small in extent, 2,500 acres and are confined principally <br />to the marginal hogbacks of the Salt Valley anticline. <br />MLRA OFFICE RESPONSIBLE: Lakewood, Colorado <br />SERIES ESTABLISHED: Grand County Utah, 1982. <br />REMARKS: Named for a ghost town near the north end of Salt Valley. <br />National Cooperative Soil Survey <br />U.S.A. <br />(REVISED 9/99) 2.04.9-56 <br />
