Mud Creek Pit -Reclamation Permit Application -112 (C) Exhibits Page 41 of 67 <br />Unit 124 <br />Name Sideshow silty clay loam, 3 to 6 percent slopes <br />Description This map unit is a soil of very deep, well drained soil located on hills, alluvial fans and <br />terraces. Elevation is 6,000 to 7,500 feet. The average annual precipitation is 13 to 16 <br />inches, the average annual air temperature is 46 to 50 degrees F, and the average frost-free <br />period is 100 to 120 days. <br />This map unit is 90 percent sideshow soil and similar inclusions and 10 percent contrasting <br />inclusions. <br />Contrasting Inclusions <br />This unit includes zigzag soils on knobs, sideslide soils on alluvial fans and Ramper soils on <br />alluvial fans. <br />Vegetation <br />The ecological site is Clayey Foothills. The dominant vegetation is 50 percent western <br />wheatgrass, 20 percent big sagebrush, 5 percent Indian ricegrass. The potential production <br />of native vegetation on these soils is 900 pounds on a normal year. <br />Soil Management Implications <br />Major uses are livestock grazing and cropland. Major management factors suitability for <br />rangeland is fair, suitability for cropland is fair and suitability for building site development is <br />poor. <br />Notes <br />Prime Farmland <br />Wind Erodibility Group:4L <br />Hydrologic Group: C <br />Detailed description of soil (Sideshow silty clay loam) <br />The sideshow silty clay loam parent material is aluvium from a Mancos shale source. <br />Sideshow silty clay is well draine nchesicslla browns layer is 0 to 3 inches is a brown silty clay <br />loam. The next layer down to 60 <br />The permeability of sideshow silty clay loam is slow. The available water capacity is high. <br />Potential rooting depth is 60 inches or more. Runoff is high, the hazard of water erosion is <br />i moderate. The shrink-swell potential is high. <br />Similar inclusions are made up of clayey surfaces on alluvial fans. <br />McStone Aggregates, LLC 15 FEB 2008 ©WASTELINE, iNC 2008 PN 5006.1-4(009 <br />
