CLASSIFICATION OF MAJOR COMPONENTS <br />• <br />Torrifluvents, nearly level; Great Group Torrifluvents. <br />INCLUSIONS <br />Included in the mapping unit are isolated areas of the Wann soils <br />(Coarse -loamy, Mixed, Mesic Fluvaquentic Haplustolls). These <br />make up 15 percent of this unit and are on 1 to 3 percent slopes. <br />Also included in mapping are small areas of moderate to severely <br />alkali affected soils. There are isolated and small areas where <br />water stands near or at the surface year round. <br />MAPPING UNIT BL - BADLAND <br />• This unit consists of steep and very steep, nearly barren land dis- <br />sected by many intermittent drainage channels that have entrenched <br />into the soft shale and sandstone of the Green River formation <br />and the soft shale and siltstone of the Wasatch, Mancos, and Mesa <br />Verde formations. About SS percent or more of this unit is unve- <br />getated. It occurs mainly on steep foothill and mountain slopes <br />that have shale or sandstone rock outcrop exposures. Water erosion <br />is very high and geologic erosion is active. The capability subclass <br />is VIIIe, non-irrigated. <br />INCLUSIONS <br />Included in the mapping unit are small isolated areas of Dollard, <br />Lazear, and Tanna soils. Dollard soils are Fine, Montmorillonitic <br />(calcareous) Frigid Ustic Torriorthents. Lazear soils are Loamy, <br />• Mixed (calcareous), Mesic Lithic Ustic Torriorthents. Tanna soils <br />2-16 <br />
