Fish Creek Soil Investigation <br />The Bw horizon has hue of SY through 7.SYR, value of 5 through 7 dry, and 3 through 6 moist, <br />with chroma of 2 through 4. It ranges from neutral to moderately alkaline. <br />A Ck horizon is present in some pedons but is absent or discontinuous in others. <br />The C horizon has hue of SY through 7.SYR. It ranges from neutral to strongly alkaline. <br />COMPETING SERIES: These aze the Abor, Barkof, Bascovv, (T)Bickerdyke, Binco, Bulklev, <br />Dutton, Gerber, Linnet, Macias, and Marvan series, all of which have a frigid temperature regime <br />except Binco. In addition, Binco soils lack a pazalithic contact within a depth of 40 inches. <br />GEOGRAPHIC SETTING: Aaberg soils aze on upland hills and ridges where shale occurs <br />above a depth of 40 inches. Slopes typically range from 2 to 65 percent. The soil formed in fine <br />textured, noncalcazeous or weakly calcazeous parent sediments weathered from underlying clay <br />shale beds. The average annual precipitation ranges from 9 to 12 inches with peak periods of <br />precipitation during the spring and eazly summer. The average annual air temperature is 37 <br />degrees F., and the average summer temperature is 57 degrees F. Elevation ranges from 8,200 to <br />8,600 feet. <br />GEOGRAPHICALLY ASSOCIATED SOILS: These are the Barishman and Bundyman soils. <br />Barishman soils lack a pazalithic contact above a depth of 40 inches. Bundyman soils have <br />continuous horizons of secondary calcium carbonate accumulation above the bedrock. <br />DRAINAGE AND PERMEABILITY: Moderately well drained; rapid runoff; slow <br />• permeability. <br />USE AND VEGETATION: These soils are used principally for native pastureland. Native <br />vegetation consists of alkali sage, western wheatgrass, and pine needlegrass. <br />DISTRIBUTION AND EXTENT: High mountain valleys ofnorth-central Colorado. The series <br />is of moderate extent. <br />MLRA OFFICE RESPONSIBLE: Lakewood, Colorado <br />SERIES ESTABLISHED: Jackson County Area, Colorado, 1973. <br /> <br />Habitat Management, Inc.
