COMODORE -ROCK OUTCROP COMPLEX <br />These soils occur in the mountainous area of Saguache County on slopes of 40 to 150 percent <br />grade or more. Comodore soils make up about 55 percent and rock outcrop about 45 percent <br />of the mapping unit. Comodore soil is ten to 20 inches thick over bedrock. <br />The rock outcrop occurs as large, steep mountainous areas of exposed rhyolite and closely <br />associated volcanic and agglomeratic materials. <br />The Comodore is a shallow, well- drained, very stone (35 percent) soil, formed in thin colluvial <br />material from igneous and metamorphic rock. Typically, the surface layer is very stony loam <br />about five inches thick. The underlying material is extremely stony loam about 120 inches thick <br />and is directly over hard igneous or metamorphic bedrock at ten to 20 inches depths. <br />Permeability is moderate. Effective rooting depth ranges from ten to 20 inches. Available <br />water capacity is moderately low. Surface runoff is rapid and erosion hazard severe. <br />
