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, and <br />Travessilla, Trayson, and Zukan soils. Farview soils are less than 10 inches to hard bedrock. <br />Redspear soils have a mean annual soil temperature of less than 50 degrees F. Rizno soils have <br />less than 18 percent clay in the particle size control section. Rizozo soils have hues of 5YR or <br />redder. Travessilla and Skyvillage soils have particle size control sections with less than 18 percent <br />clay. Zukan soils are over limestone bedrock and have an horizon of carbonate accumulation. <br />Trayson soils contain less than 18 percent clay in the control section. Similar soils and previously <br />competing series are 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 competing <br />Travessilla soils. Shavano soils have a lithic contact at depths greater than 20 inches and <br />Travessilla soils contain less than 18 percent clay in the particle size control section. <br />DRAINAGE AND PERMEABILITY: well drained, negligible to high runoff, moderate permeability <br />USE AND VEGETATION: These soils are used principally as native pastureland. Native vegetation <br />is galleta grass, cactus, greasewood, and snakeweed. <br />DISTRIBUTION AND EXTENT: The foothill areas of western and southwest Colorado and adjacent <br />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 />REMARKS: Diagnostic horizons and features recognized in this pedon are: <br />ochric epipedon: The zone from 0 to 4 inches. (A) <br />lithic contact: The zone at 14 inches. (R). <br />Taxonomy version, 7th Edition 1996 <br />Secondary carbonates usually coat the surface of the bedrock. <br />Particle size control section: The zone from 0 to 14 inches.
