Fish Creek Soil Investigation <br />size control section. Lotex soils have hue of SYR or redder. Spliten and Udelope soils receive <br />most of their moisture in the winter and early spring. Taylow soils have a xeric moistwe regime. <br />Tuggle soils have a paralithic contact above the lithic contact. <br />GEOGRAPHIC SETTING: Splitro soils are on upland hillslopes, mountain slopes, structwal <br />benches and ridges. Slope gradients range from 0 to 65 percent. These soils formed in medium <br />textwed alluvium, residuum, and eolian materials derived dominantly from sandstone. In <br />Colorado some areas aze derived from basalt. Precipitation is 18 to 25 inches, with peak periods <br />of precipitation occurring in the spring and eazly swnmer. Mean annual temperatwe is 36 to 40 <br />degrees F. Elevation is 6,500 to 9,200 feet. The frost-free season is 60 to 90 days. <br />GEOGRAPHICALLY ASSOCIATED SOILS: These are the Passcreek and Sawcreek soils. <br />Both of these soils are moderately deep and occw on lowland hillslope positions and broad <br />summits. <br />DRAINAGE AND PERMEABILITY: Well drained; slow to rapid runoff; moderate to rapid <br />permeability. <br />USE AND VEGETATION: These soils are used principally as native pastweland or for <br />recreational purposes. Native vegetation is green needlegrass, Idaho fescue, and yarrow. May <br />have scattered ponderosa pine and quaking aspen. <br />DISTRIBUTION AND EXTENT: The Bighorn Mountain azeas ofnorth-central Wyoming and <br />~ the western slope of Colorado. The series is of moderate extent. <br />C~. <br />MLRA OFFICE RESPONSIBLE: Bozeman, Montana <br />SERIES ESTABLISHED: Lower Colorado Area, Colorado 1970. <br />REMARKS: Diagnostic horizons and featwes recognized in this pedon are: <br />mollic epipedon - 0 to 8 inches (A) <br />Iambic horizon - 8 to ]6 inches (Bw) <br />]ithic contact - 16 inches (R) <br />MLRR- E <br />SIR- WY0062, WY0845, WY]390 <br />National Cooperative Soil Survey <br />U.S.A. <br />J <br />Habitat Management, Inc.
