Water Resources <br />The pit is situated in the Headwater Dripping Rock Creek HUC, between the <br />West and East Twin Washes. See Map 2 and Appendix E, Map E6. <br />Soils, Geology, and Vegetation <br />In 1995 during the permitting and reclamation planning process, the Natural <br />Resources Conservation Services (NRCS, Appendix G) classified the pit as <br />follows: <br />• Torriorthents-Rock outcrop, shale complex with 30-75% slopes as the <br />majority of the location, current MUSYM# 198. <br />Eghelm, loamy fine sand with 0-3% slope, current MUSYM# 62. <br />The Geology Quadrangle Mellen Hill, 1969 has resolution and more detail <br />then the available soils maps (Map 3 - 4 and Appendix E). We concur with <br />the NRCS classification of Torriorthents- Rock outcrop, shale complex but <br />would like to add the Torriorth ents- Rock outcrop, sandstone complex. This <br />addition to the soils is based upon the complex geology shown in the geologic <br />Map 4. Using ArcMap, it was determined that 7.9 acres (80%) of the pit is <br />Torriorth ents- Rock outcrop. <br />The NRCS further determined that the portion of the site classified as <br />Eghelm, loamy fine sand would fall into Saltdesert Overflow range site class. <br />No range site description was given for the Torriorthents-Rock outcrops. <br />Soil depth to bedrock or a restrictive feature, in the Torriorthents (MUSYM# <br />198, 197 and 160) classification is 0-8 inches of a silty clay loam with 8-12 <br />being weathered bedrock (Schroeder, 2004). The rocky outcrop portions are <br />defined as areas with less than 4 inches of soil over shale or bedrock. <br />R -)R: I'"W LI_ GRAVI L 1111. \11." 1A UI I. x.71.
