Hue: 7.5YR to 2.5Y <br />Value: 5 to 8 (4 to 6 moist) <br />Chroma: 2 to 4 <br />Texture: loam or clay loam <br />Rock fragments: 0 to 35 percent <br />Calcium carbonate equivalent: 1 to 6 percent <br />EC (mmhos/cm): 0 to 1 <br />Reaction: slightly to strongly alkaline <br />COMPETING SERIES: These are the Farview, Redspear, Rizno, Rizozo, Skyvillage, <br />and Travessilla, Travson, and Zukan soils. Farview soils are less than 10 inches to hard <br />bedrock. Redspear soils have a mean annual soil temperature of less than 50 degrees <br />F. Rizno soils have less than 18 percent clay in the particle size control section. Rizozo <br />soils have hues of 5YR or redder. Travessilla and Skyvillage soils have particle size <br />control sections with less than 18 percent clay. Zukan soils are over limestone bedrock <br />and have an horizon of carbonate accumulation. Travson soils contain less than 18 <br />percent clay in the control section. Similar soils and previously competing series are <br />Gladel. The Gladel soil was reclassified to an Ustochrept. <br />GEOGRAPHIC SETTING: <br />Parent material: residuum derived from interbedded shales, loamstone, and sandstone <br />Landform: hills, mesas, and ridges <br />Slopes: 0 to 65 percent <br />Elevation: 4,800 to 6,200 feet <br />. Mean annual temperature: 47 to 56 degrees F <br />Mean annual precipitation: 10 to 13 to inches <br />Frost-free period: 120 to 140 days <br />GEOGRAPHICALLY ASSOCIATED SOILS: These are the Shavano soils and the <br />competing Travessilla soils. Shavano soils have a lithic contact at depths greater than <br />20 inches and Travessilla soils contain less than 18 percent clay in the particle size <br />control section. <br />DRAINAGE AND PERMEABILITY: well drained, negligible to high runoff, moderate <br />permeability <br />USE AND VEGETATION: These soils are used principally as native pastureland. Native <br />vegetation is galleta grass, cactus, greasewood, and snakeweed. <br />DISTRIBUTION AND EXTENT: The foothill areas of western and southwest Colorado <br />and adjacent parts of Wyoming. LRR D, MLRA 34B. This series is of moderate extent. <br />MLRA OFFICE RESPONSIBLE: Phoenix, Arizona <br />SERIES ESTABLISHED: Delta County, (Paonia Area) Colorado. 1970. <br />.
