<br />102 - Rombo Taxajunct. 20 to 50 percent slopes. <br />The Rombo Taxajunct soil is moderately deep and <br />well-drained. It developed from coll~zvial and alluvial <br />material derived from upslope sandstone and shale. Small <br />areas of Prieta Variant, Fort Collins Variant and Rock Outcrop <br />were included in mapping. Prieta Variant soils are shallow <br />and more clayey. Fort Collins Variant soils are deep with <br />more developed horizons. These soils and lands occupy less <br />than 15 percent of the mapping unit. <br />In a typical profile, the surface layer is brown flaggy <br />loam about 4 inches thick. The upper subsoil is grayish brown <br />loam about 21 inches thick. The lower subsoil is yellowish <br />• brown channery clay loam about 8 inches thick and is underlain <br />with highly fractured sandy shale at a depth of 33 inches. <br />The Rombo Taxajunct soil has moderate permeability and <br />medium runoff. The erosion hazard is moderate. Available <br />water holding 'capacity is moderate. Effective rooting depth <br />is 20 to 40 inches. <br />This soil is used for livestock grazing and wildlife <br />habitat. The vegetation is primarily Gambel oak, pinyon pine, <br />juniper and blue gram a. <br />The average depth of suitable topsoil material is 24 <br />inches. This material is rated fair to good with suitability <br />decreasing with depth due to increasing clay and coarse <br />fragment content and bedrock at 20 to 40 inches.. <br />
