ELKHORN SPRINGS This pit is located 10~ miles north of Hwy, 24 on the Elkhorn Road. The site is on a Southeast facing slope. The precept of slope is 8%. The area has been used as range land with several subdivisions in the vacinity. Soils The soils at this site are Soils Unit 20D. This mapping unit occurs on gently sloping to sloping mountain slopes. These soils are developing on Pikes Peak granite. They are shallow to moderately deep and are gravelly through- out. Most of the surface has scattered gravel and in places, cobble. In a tew places rock outcrop occurs. The surface layer ranges in thickness from 3 to 10 inches. It is dark colored and is gravelly sandy loam. The sub- soil ranges in texture from gravelly heavy sandy loam to gravelly clay loam. The material underlying the subsoil is disintegrating Pikes Peak granite, mostly gravel and{ or cobble with a sandy loam matrix. In some places hard bedrock may occur at depths from 20 to 40 inches. Disin- tegrating granite occurs at depths of 6 to 15 inches. These soils are subject to severe water erosion when the surface is not protected by adequate vegetative cover. The water intake rate is moderate. The water holding capacity is moderate to low. This soil is shallow to moderately deep. It occurs on rolling to steep mountain slopes. It is developing on Pikes Peak granite. At the type location this soil is on a 38 percent slope facing south. The elevation is approximately 9,250 feet.
