--12 inches; fractured calcareous sandstone. <br />TYPE LOCATION: Grand County, Utah. About 4.5 miles south of Cresent Junction on U. S. Highway <br />160; East of railroad tracks; SE 1/4, SW 1/4, sec. 22, T. 22 S., R. 19 E. <br />RANGE IN CHARACTERISTICS: Depth to bedrock ranges from 10 to 20 inches. The particle-size <br />control section ranges in texture from very stony sandy clay loam, or very stony clay loam. Clay content <br />ranges from 18 to 35 percent. Rock fragment content is 35 to 70 percent in the particle-size control <br />section and consists of mainly of stones and cobbles, but some pebble size fragments are present. The <br />mean annual soil temperature is 54 to 59 degrees F. <br />The A horizon has hue of 7.5YR, value 5 or 6 dry, 4 or 5 moist, and chroma of 3 or 4. <br />The Bt horizon has hue of 7.5YR, value 5 or 6, dry, 4 or 5 moist, and chroma of 4. Texture is very <br />gravelly clay loam, very stony sandy clay loam, or very stony clay loam. <br />The BCk horizon has hue of 10YR or 7.5YR, value of 6, 7, or 8 dry, 4, 5, or 6 moist, and chroma of 3 <br />or 4. It is strongly calcareous or very strongly calcareous. Texture is very stony sandy clay loam, very <br />gravelly clay loam, or very stony clay loam. In some pedons, gravelly sandy loam, very stony clay loam, <br />clay loam, very gravelly loam, very stony clay loam, and very stony loam strata are present. <br />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 inches. <br />The freeze-free period is 150 to 170 days. <br />(Revised June 2008) Attachment 2.04.9-3-41
