2.04.9 Soils Resource Information <br />(1) In general, the soils within the proposed disturbed area are shallow to deep, <br />moderately steep to very steep, well drained stony soils that formed in <br />residuum, colluvium, and alluvium derived from sedimentary rock and rock <br />outcrop. The soils in the northern portion of the permit area, above the <br />proposed disturbed area, are deep, nearly level to steep, well drained loam <br />and stony loam that formed in outwash from igneous rock. <br />(1)(a) Description, sampling and analysis of soil horizons in sufficient detail to determine <br />the horizons suitable for salvage. <br />The area to be disturbed by the surface operations and facilities at the mine <br />site were segregated into six map units numbered 1 through 6. <br />Map Units 1. 2 and 3 <br />Map units 1, 2 and 3 are the Absarokee part of the Beenon - Absarokee <br />association, 20 to 60 percent slopes. The Absarokee soil is well drained and <br />overlies bedrock at a depth of 20 to 40 inches. It formed in locally <br />transported sediment derived from sandstone and interbedded shale. <br />Typically the surface layer of the Absarokee soil is dark grayish brown loam <br />about 7 inches thick. The subsoil is brown clay about 18 inches thick. The <br />substratum is light brown channery clay loam. Sandstone is at a depth of <br />about 30 inches. <br />Field investigation of this map unit shows the soil has virtually no profile <br />which is contradictory to the general soil description. The thickness of the A <br />horizon averaged only 1.5" to 2.5 ". The soil is deep with a combined A and B <br />horizon depth that ranges from 22" to 38 ". Laboratory tests show this soil is <br />a silt loam and silty clay loam and medium to dark red -brown in color. Based <br />on the soil's physical, fertility and salinity characteristics presented in Exhibit <br />7, the A and B horizon are suitable for salvage. <br />PR -14 2.04-74- 03/14 <br />
