Dowe Flats Quarry Soils and Geology Report <br /> The C horizon has hue of 5Y through IOYR. It is moderately alkaline or strongly alkaline and <br /> contains about 2 to 8 percent calcium carbonate equivalent. Usually there are a few crystals of <br /> calcium sulfate throughout this horizon but amount and placement of visible secondary calcium <br /> carbonate and calcium sulfate is erratic from pedon to pedon and horizons are discontinuous. <br /> COMPETING SERIES: These are the Biedsaw, Bodot, Bone, and Vananda series. Bodot soils <br /> are dry in some part of the moisture control section from April to July 15. Bone soils have a thin <br /> horizon that qualifies as a natric horizon except for thickness. Biedsaw and Vananda soils lack a <br /> paralithic contact above a depth of 40 inches. <br /> GEOGRAPHIC SETTING: The Gaynor soils are on hill sides and ridge crests. Slope gradients <br /> range from about 2 to 60 percent. These soils formed in thin calcareous sediments weathered <br /> residually from sedimentary rock. At the type location the average annual precipitation is 18 <br /> inches, with peak periods of precipitation during the spring and summer. Mean annual <br /> temperature is 48 degrees F, and the mean summer temperature is 68 degrees F. <br /> GEOGRAPHICALLY ASSOCIATED SOILS: These are the Limon and Samsil soils. In some <br /> landscapes they form a topographic sequence with the Samsil and Limon series. Limon soils <br /> have no bedrock above a depth of 40 inches. Samsil soils are less than 20 inches deep over shale. <br /> DRAINAGE AND PERMEABILITY: Well drained; medium to rapid runoff; moderate to <br /> slow permeability. <br /> USE AND VEGETATION: Used as native pastureland and for dry or irrigated crop land. <br /> Principal native vegetation is blue grama, western wheatgrass, and cactus. <br /> DISTRIBUTION AND EXTENT: Eastern and east-central Colorado and Wyoming. The series <br /> is of moderate extent. <br /> MLRA SOIL SURVEY REGIONAL OFFICE (MO) RESPONSIBLE: Bozeman, Montana <br /> SERIES ESTABLISHED: Johnson County (Southern Johnson Area), Wyoming, 1971. <br /> National Cooperative Soil Survey <br /> U.S.A. <br /> 16 May 2, 2022 <br />
