Permeability is rapid, and the available water capacity is very low. Runoffis rapid, and <br />the hazard ofwater erosion is moderate." <br />"Typically, 40 to 65 percent of the surface is covered with vegetation and forest litter. <br />The surface layer is brown gravelly coarse sandy loam about 4 inches thick. The next <br />layer is yellowish brown very gravelly loamy coarse sand about 8 inches thick. Highly <br />weathered, coarse grained granite, or gnus, is below a depth of about 12 inches." <br />"About 5 percent of this unit is included areas of Garber very gravelly coarse sandy loam <br />on mountainsides, commonly adjacent to drainageways; 10 percent is soils that have a <br />surface layer that is darker than that of the Sphinx soil; and 5 percent is areas of outcrop <br />of Pikes Peak granite on mountainsides and ridges." <br />"This soil is best suited to wildlife habitat, watershed, recreation, and limited timber <br />production. Because of the aspect and climatic conditions, it is somewhat more heavily <br />vegetated than the warm phase of the Sphinx series. It is very susceptible to erosion if <br />the cover of plants and forest litter is disturbed. The major limitations affecting the <br />production and harvest of timber are a high susceptibility to erosion, low natural fertility, <br />and the depth to bedrock." <br />I concur with the above statements from the NRCS and add my observations below to <br />further clarify. <br />The Pikes Peak granite outcrops on about 10 percent of the areas of the claim areas <br />Some areas presently have no soil because they are disturbed areas and the soil has <br />previously been removed. Soil is also absent on numerous rock outcroppings which are <br />where several of the dig sites are located (The pegmatites are in and around rock <br />outcroppings). <br />Other areas are gravel slopes where soil is minimal or near absent. Erosion is apparent <br />on these slopes and in these areas. <br />The areas with the deepest soils are located under mature pines where, locally, there can <br />be deep layers of duff and decomposing needles in those areas not burned by the Hayman <br />fire. <br />The average soil in undisturbed dig sites is typically shallow (to 4 inches) with poorly <br />defined subsoils (to 8 inches total). <br />The soils are ganitic in composition and therefore, both permeable and porous. Severe <br />rain wilt create erosion in these soils; however, most precipitation is rapidly absorbed and <br />runoff is minimal. These soils are most susceptible to erosion during flash flooding <br />caused by heavy thunderstorms. <br />
