EXIMBIT I—SOILS INFORMATION <br /> The proposed land use consists of two soil types within the affected land <br /> boundaries, Martindale sandy loam and Resort very gravelly sandy loam The majority <br /> of the mining will take place in the Resort very gravelly sandy loam According to the <br /> Soil Survey of Fremont County, Martindale is a deep, well-drained soil found on fans <br /> and foot slopes of intermontane basins. This soil formed in mixed alluvium. The surface <br /> layer is typically a dark brown sandy loam about 5 inches thick. The subsoil is mainly <br /> sandy clay loam about 40 inches thick. The substratum to a depth of 60 inches or more is <br /> gravelly sandy loam. This soil is typically neutral to a depth of 11 inches and is <br /> moderately alkaline below that depth. The lower 24 inches of the subsoil has a high <br /> content of accumulated calcium carbonate. Permeability is moderately slow in the <br /> Martindale soil. Available water capacity is high. Effective rooting depth is 60 inches <br /> or more. Runoff is slow to rapid, and the hazard of water erosion is slight it very high. <br /> The native vegetation is mainly grasses. The potential plant community consists of <br /> western wheatgrass, need leandthread, blue grams, and fringed sagebrush A site specific <br /> shows the Martin ale soil to be any where from 2 to 8 feet deep. As the Martinsdale soil <br /> enters the Resort soil, within the affected land boundaries, the soil dept decreases. The <br /> Martindale soil consists of meadows containing large percentages of blue grama grass <br /> and fringed sage. <br /> The second type of soil within the affected land boundaries is the Resort very <br /> gravelly sandy loam. This shallow, somewhat excessively drained soil is found on <br /> mountainsides. It formed in residuum derived dominantly from granodiorite. The <br /> surface layer is typically dark grayish brown very gravelly sandy loam about 8 inches <br /> thick. The subsoil is very gravelly sandy loath about 4 inches thick. The substratum is <br /> extremely gravelly loamy sand about 5 inches thick. It is underlain by soft, weathered <br /> granodiorite. The soil is neutral. In some areas the surface layer is a very cobbly, sandy <br /> loam Permeability is rapid in the Resort soil. Available water capacity is very low and <br /> effective rooting depth is 10 to 20 inches. Runoff is medium to rapid and the hazard of <br /> water erosion is moderate to very high. The potential plant community is mainly pinyon <br /> and juniper with an understory of mountain muhly, mountain mahogany, and Gambel <br /> oak. A site specific of the Resort soil showed in, three test pits, the soil to be from 1 to 2 <br /> feet thick. The underlying layer consisted of decomposed granite to 10 feet thick follow <br /> by bedrock. The Resort soil consists of woodlands containing pinyon,juniper and <br /> ponderosa pine. The mature woodland will be cut and cleared. Soil will be stockpiled <br /> fnr later reclamation purposes. <br /> 11 <br />
