• • Draft <br />6-TS AP <br />-Rock Outcrop - Un (Cabrini) - Retake Codex, 50 to 100 <br />c i..,.e~ ._ _- <br />Shis complex occupies mountain sideslopes and canyon malls. The <br />soils formed in gravelly, loam. material derived from metamorphic e~ <br />igneous rocks. - - - . <br />Average amuel precipitation ranges from 17 to 19 inches. Mann <br />annual temperature is about 46° F. Frost free season ranges from 76 <br />to 125 days. Elevations range from 6500 to 7800 feet. Aspects_ are <br />generally south, east, and vest. <br />Rock outcrop makes up about 55 percent of the mapping unit and <br />occupies ridge crests and steeper sideslopes. Un (Cabrini) soils make <br />up sbout 15 percent of the mapping unit and occupy sideslopes over hard <br />bedrock. Retake soils make up about 15 percent of the mapping unit and <br />occupy sideslopes over soft bedrock. <br />Included are Curecanti and Lininger soils, end talus slopes. <br />Curecenti soils lack bedrock above 40 inches depth and occupy toeslope <br />fill positions. Lininger soils have bedrock between 20 and 40 inches <br />depth end occupy small coves and depressions. Talus slopes generally <br />occur adJacent to a Large rock outcrop. Total inclusions are less than <br />" 15 percent of the mapping unit area. "' <br />Rock outcrop consists mainly of large bnuldera and exRosures of <br />lgneous and metamorphic rocks. <br />Ua (Cabrini) soil is a shallow, yell drained soil on mountain <br />sideslopes. It formed in noncalcareous mixed material derived from <br />igneous and metamorphic rocks. <br />Typically the surface layer is dark brown very stogy sandy loam <br />about 11 inches thick overlying hard bedrock. - <br />Permeability is moderate, and available water capacity is low. <br />Effective rooting depth is 20 inches or less. Surface runoff is rapid, <br />and erosion hazard is high. Shrink-swell potential is low. Depth to <br />lard bedrock is less than 20 inches. Surfaces ase very stony. <br />Retake soil; is a shallow, yell drained soil on mountain sideslopes. <br />It formed in noncalcareous mixed material derived from igneous and <br />metamorphic rocks. <br />Typically the surface layer is dark brown very stogy sandy loam <br />about 12 inches thick overlying soft bedrock. <br />Permeability is moderate, and available xater capacity is low. <br />Effective rooting depth is 20 inches or less.
