• <br />CLASSIFICATION OF MAJOR COMPONENTS <br />Torriorthents - Rock Outcrop complex, very steep; Great Group <br />Torriorthents. <br />INCLUSIONS <br />Included in mapping are small isolated areas of Ildefons, Lazear, <br />Ansari, Gaynor, Tridell, and Nihill soils. Ildefonso soils are <br />loamy-skeletal, mixed, mesic Ustollic Calciorthids. Lazear soils <br />are loamy, mixed (calcareous), mesic Lithic Ustic Torriorthents. <br />Ansari soils are loamy, mixed Lithic Haploborolls. Tridell soils <br />are loamy-skeletal, mixed Aridic Argiborolls. Nihill soils are <br />loamy-skeletal, mixed (calcareous), mesic Ustic Torriorthents. <br />There was not a higher taxonomic class available for the Gaynor <br />soils from the SCS fieldwork. These intermittent areas make up <br />• 10 to 15 percent of this map unit. <br />MAPPING UNIT RLS - TORRIORTAENTS - CAMBORTHIDS <br />ROCK OUTCROP COMPLEX, STEEP <br /> <br />This broadly defined unit consists of exposed sandstone and shale <br />bedrock, loose stones, and soils that are shallow to deep over <br />sandstone and shale bedrock and stony basaltic alluvium. The <br />soils and outcrops are moderately steep to very steep. This com- <br />plex is in capability subclass VIIe., non-irrigated. <br />Torriorthents make up about 45 percent of the complex, Camborthids <br />make up 20 percent, and Rock Outcrop makes up 15 percent. The <br />moderately steep Camborthids are on lower toe slopes and concave <br />open areas on foothills and mountainsides. <br />I-18 <br />
