• Chroma: 2 to 4 <br />Rock fragments: 0 to 35 percent <br />EC (mmhos/cm): 0 to 1 <br />Reaction: slightly to strongly alkaline <br />C horizon: <br />Hue: 7.5YR to 2.5Y <br />Value: 5 to 8 (4 to 6 moist) <br />Chroma: 2 to 4 <br />Texture: loam or Gay loam <br />Rock fragments: 0 to 35 percent <br />Caldum carbonate equivalent: 1 to 6 percent <br />EC (mmhos/cm): 0 to 1 <br />Reaction: slightly to strongly alkaline <br />COMPETING SERIES: These arethe Farview, Redspear, Rizno, Rizozo, Skyvillage, and Travessilla, Travson, and <br />Zukan soils. Farview soils are less than 10 inches to hard bedrock. Redspear soils have a mean annual soil <br />temperature of less than 50 degrees F. Rizno soils have less than 18 percent day in the partite size control section. <br />• Rizozo soils have hues of 5YR or redder. Travessilla and Skyvillage soils have partite size control sections with <br />less than 18 percent Gay. Zukan soils are over limestone bedrock and have an horizon of carbonate acwmulation. <br />Travson soils contain less than 18 percent day in the control section. Similar soils and previously competing series <br />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 Travessilla soils. <br />Shavano soils have a lithic contact at depths greater than 20 inches and Travessilla soils contain less than 18 <br />percent clay in the partite size control section. <br />• <br />(Revised March 2006) Attachment 2.04.9-3-21 <br />
