COMPETING SERIES: These are the Hoot, Mirkwood (T), Theon (T), and Waucaba series. All these <br />soils receive most of their annual precipitation during the winter months and receive little or no <br />precipitation after the summer solstice. Hoot soils have loam, silt loam, clay loam, or silty clay loam <br />textures in the particle -size control section. They are neutral to mildly alkaline in the argillic horizon. <br />Theon soils are dominated by pebble sized fragments in the subsoil and are formed in granitic parent <br />material. They have a paralithic contact above the lithic contact. Waucaba soils are dominated by <br />pebble and 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 the Salt Valley <br />anticline, Burro Canyon Formation. Slopes are medium and long in length and range from 8 to 25 <br />percent. The soils are formed in colluvium and residuum and mostly from calcareous sandstones and <br />shale. Mean annual temperature is 52 to 57 degrees F and average annual precipitation is 5 to 8 <br />inches. The freeze -free period is 150 to 170 days. <br />GEOGRAPHICALLY ASSOCIATED SOILS: These are the Farb, Monue, and Chipeta soils. Farb soils <br />have a loamy particle -size control section and lack a B horizon. Monue soils lack bedrock above a depth <br />of 40 inches. Chipeta soils are less than 20 inches to paralithic contact. <br />DRAINAGE AND PEREMABILITY: Valleycity soils are well drained, medium runoff; and moderate <br />permeability. <br />USE AND VEGETATION: These soils are used for rangeland; wildlife habitat and for recreation. <br />Potential vegetation includes galleta, shadscale, Indian ricegrass, blackbrush, rabbitbrush, and <br />pricklypear. DISTRIBUTION AND EXTENT: Southeastern Utah. The soils of this series are small in <br />extent, 2,500 acres and are confined principally 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.
