1 <br />1 <br />1 <br />EXHIBIT I <br />SOILS INFORMATION <br />The mining site is located on what is described as high <br />terraces between the mountains and the bottom lands. The <br />U.S. Soil Conservation Service has classified the soils as <br />being in the Rough Broken land - Badland association with <br />moderately steep and steep slopes on severely eroded sedi- <br />ments. Current gravel mining as well as some future opera- <br />tions will be conducted in a drainageway between two steep <br />ridges. The soil in the drainageway has been formed on <br />alluvial material which is a mixture of sand, silt, clay, <br />gravel and cobble. In some areas, this valley soil~has a <br />fair to good sandy loam topsoil for a thickness of approxi- <br />mately 12 inches. <br />The ridges result from dissections of the landscape by <br />erosion. They generally have slopes steeper than 45 percent. <br />Soil in parent material consists of highly stratified sedi- <br />ments of the Dry Union Formation. According to the Soil <br />Conservation Service, most of this land is calcareous and <br />has pockets of high lime accumulation. Surface runoff is <br />rapid and the hazard of erosion is high. <br />Soil was sampled at the 0-6 inch and 6-12 inch depth <br />on the top of the ridge near the present pit. Soil texture <br />was estimated to be a sandy loam with the shallower depths <br />I-1 <br />
