Range in Characteristics These soils are extremely variable in characteristics. The depth to shale ranges from 10 to 60 inches or more. The particle -size control section is 15 to 35 percent rock fragments, and the clay content is 27 to 60 percent. A horizon: The hue is 7.5YR, 2.5YR, 2.5Y, IOYR. The texture is bouldery clay loam, stony loam, bouldery sandy loam, very gravelly clay loam, or clay loam. C horizon: The hue is 2.5YR, 2.5Y, 5Y, 5YR. The texture is cobbly clay loam, silty clay loam, clay or clay loam. NRCS SOILS SURVEY PHYSICAL AND CHEMICAL PROPERTIES The typical ranges of the physical properties of these seven soils mapping units as found in the NRCS Soils Survey are found in Table 2.04.9-4, NRCS Physical Properties of the Soils. The typical ranges of the chemical properties of these seven soils mapping units as found in the NRCS Soils Survey are found in Table 2.04.9-5, NRCS Chemical Properties of the Soils. WESTERN FUELS 2008 SOILS SURVEY In November of 2008, a total of 183 backhoe pits were dug in a systematic pattern as shown on Map 2.04.9-2, New Horizon North Mine - Soils Map and Map 2.04.9-3, New Horizon North Mine - Topsoil Salvage Map. At each of these soils pits, the backhoe dug down to the depth of bedrock, or just below this layer and a formal soil pedon description was taken at each test pit. The form used to record the soil pedon information at each soil test pit is the United States Forest Service SOILS FIELD FORM FOR PEDON DESCRIPTION. This form was used in lieu of the NRCS form, because it allows for coarse fragments to be broken down into four different size categories instead of the one category found on the NRCS form. At each soil test pit the depth of each diagnostic soil horizon was measured, the dry and moist color recorded, the presence of soils pores, root categories, field texture determined, soil structure determined by the feel method, soil consistence in terms of dry, moist, wet and plasticity determined, the presence of clay films determined, the coarse fragments recorded in terms of fine gravels, coarse gravels, cobbles and stones. Notations were also made on the boundary conditions of each soil horizon. Copies of these 183 backhoe soils pedon descriptions are found in Appendix 2.04.9-1, Soils Pedon Descriptions. Each soils test pit was then photographed, duplicate samples were collected in one gallon plastic bags for laboratory analysis, the exposed soil horizons photographed and then backfilled. As directed by the DRMS, copies of the photographs of most of the soils backhoe test pit are found in Appendix 2.04.9-2. Soils Test Pit Photographs. Due to a computer mistake, the photographs of the soils test pits from the Garvey Property were accidentally deleted from the computer after they were downloaded from the digital camera and were lost. One of the major purposes for this soils testing program was to identify the depth of salvage topsoil at each soils test pit location. Section 2.04.9 Page 26 Sept. 2015 (TR -11)
