Torriorthents are shallow to moderately deep. They are generally <br />• clayey to loamy and contain variable amounts of gravel, cobbles <br />and stones. The surface is normally covered with stones weathered <br />from the higher lying Rock Outcrop. South of the Colorado River, <br />basaltic stones and cobbles are on the surface. <br />Camborthids are shallow to deep. They are generally clayey to <br />loamy and have slightly more clay in the subsoil than in the surface <br />layer. The surface layer is light colored. The profile is normally <br />free of stones, but scattered basalt stones, cobbles and sandstone <br />fragments are on the surface. <br />The Rock Outcrop is mainly Mesa Verde sandstone and Wasatch shale. <br />Some areas are covered with basaltic boulders and stones. Small <br />areas of limestone outcrops and exposed gypsum are in the eastern <br />part of the survey area. <br />• CLASSIFICATION OF MAJOR COMPONENTS <br />Torriorthents - Camborthids - Rock Outcrop complex, very steep; <br />Great Group Torriorthents. <br />INCLUSIONS <br />Included in mapping are small, isolated areas of Ildefonso, Lazear, <br />Ansari, Begay, Heldt, and Dollard soils. Begay soils are coarse- <br />loamy, mixed, mesic Ustollic Camborthids. Heldt soils are fine, <br />montmorillonitic, mesic Ustertic Camborthids. Higher taxonomic <br />classes for the remaining soils are available in the Inclusion <br />section of Mapping Units BL and RLX. These intermittent areas <br />make up 10 to 20 percent of this map unit. <br />• <br />I-19 <br />
