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 Travessilla <br />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 is <br />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 3413. 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.
