<br />Samples were collected from the genetic horizons of the described <br />soil. A boxed sample was collected for convenient future <br />reference. Four samples were collected. <br />At the south crossing, the soil mapping of the SCS was briefly <br />checked. The soils at the south crossing were similar to the <br />soils at the north crossing. The major soils at the south <br />crossing were not sampled or described in detail. <br />Laboratory characterizations are presently being made of the <br />sampled pedon. Tests are being conducted by Colorado Analytical <br />Laboratory in Brighton, Colorado. The tests are: <br />o pH <br />o Electrical conductivity <br />o Saturation percent <br />o SAR (Sodium adsorption ratio) <br />o Na <br />o Mg <br />o Ca <br />o Particle size distribution (sand, very fine sand, <br />silt, clay, coarse fragments) <br />o Organic matter <br />Recommendations for one of the soils as reclamation material are <br />provided. The recommendations for use of the Nihill channery <br />loam, 1 to 6 percent slopes is based on the detailed profile <br />description, SCS data, and professional experience with the Nihill <br />at other sites. The recommendation for use of the Nihill channery <br />loam, 6 to 25 percent slopes is based on brief field observations, <br />and SCS data. The other recommendations are based on brief field <br />observations, SCS data for Garfield County, and the Harney and <br />White soil inventory for the permit area. <br />STUDY AREA DESCRIPTIONS <br />North Crossing <br />Three soils occur at the north crossing: <br />o The N1hi11 channery loam <br />o Detra channery loam <br />o Typic Torrifluvents <br />The Nihill channery loam occurs in the meadow and on the south <br />facing toe slopes on the north end of the alignment. The <br />vegetation is alfalfa in the meadow and sagebrush on the slopes. <br />The Detra channery loam is limited to a small area of oak brush on <br />the north facing toe slopes at the south end of the alignment. <br />The Typic Torrifluvents occur along the channel of the west fork <br />of Parachute Creek under cottonwoods and other riparious <br />vegetation. The soil series are described in Table 1. <br />5 <br />
