SITE DESCRIPTION EXHIBIT B <br /> SOILS INFORMATION <br /> The following information was obtained from site observations and the <br /> basic soils and vegetation information found thru the USDA's National Soils <br /> information page and the Soil Survey of Huerfano County. The following soil <br /> information is made part of this application. Soil units are shown on the <br /> USDA map, reproduced on page 5 following this text. The photo map shows the <br /> surrounding vegetation features and soil types. This site lies on a mesa top <br /> terrace deposit of gravel that runs east/west in the northern part of Huerfano <br /> County. There are two soils types found on the mine site. <br /> The 57 -Nunn clay loam, 0 to 3%slopes soil series covers approximately 6.9 <br /> acres or 69% of the mine area. The general soils description indicates that <br /> the Nunn series consists of very deep, well drained soils that formed in loess <br /> and mixed alluvium. Nunn soils in this area is on a terrace or alluvial fan on <br /> the mesa top. The upper most horizon is a 0 to 12 inches or an average of 8 <br /> inches of a gravely loam, or brown, fine grained soil usable as topsoil. <br /> Underlying the topsoil is a 25 to 35 foot lens of gravely sand. The bedrock <br /> that underlays the gravel is part of the Pierre Shale and is described as a <br /> predominantly siltstone/ claystone in excess of 3000 feet deep. The top of <br /> this layer will become the mine floor. <br /> The 84- Ustic Torriorthents - Rock outcrop complex,4 to 40%slopes soil series <br /> covers approximately 3 .17 acres or 31% of the mine area. The general soil <br /> description indicates that this soil is in extremely rough, deeply eroded <br /> areas along the mesa front. They are shallow and moderately deep and well <br /> drained, soils due to the rock associated with them and the steep face they <br /> lay on. On the mine area there is little or no salvageable topsoil or growth <br /> medium material on the face. <br /> AUSTIN& BETSY CLENNIN- BECKER PIT March 6, 2020 <br /> 4 <br />
