MAP UNIT CuC: COLITIS-LIKE FINE SANDY LOAM, 8 TO 15 PERCENT SLOPE <br />• <br />This deep To very deep, well-drained, coarse textured soil occurs in areas below <br />sandstone rock outcrops. This soil is formed on moderately steep alluvial fans and <br />toe-slopes from sandstone residuum. This soil occurs in Section 13 and 14, T.SN <br />R.86W at 6,700 to 6,800 feet elevation. <br />The mapping unit does not vary significantly from the parameters reported for <br />the series description, Coutis-like fine sandy loam, pedon #05-04-23-046. <br />Presently this soil is used for livestock grazing and rangeland. Vegetation <br />consists of Artemisia tridenTata big sage, Chrysothamnus ss ., rabbitbrush, 5ym- <br />phoricarpos ss~. snowberry as well as grasses such as: Bouteloua ssp., gamma grass <br />and Lolium erp enne annual rye grass. <br />Permeability is moderate to moderately rapid. Erosion hazard is slight to <br />moderate. Depth to water Table is usually greater than S feet; fluctuations in water <br />table depth occur when the soil is on alluviol fans. <br />A Coutis pedon sampled near Foidel Creek had visible mottles at the 5 foot <br />depth. Stoniness class ranges from 3 to 4. Effective rooting depth is about 60 <br />inches. <br />• Land capability unit is Vle. <br />MAP UNIT AW: CRYAQUOLL-FLUVA~UENT COMPLEX <br />The Cryaquoll-Fluvaquent is composed of various soil types which occur <br />randomly on level to nearly level alluvial valley floors located adjacent to creeks <br />throughout The study area. The soils included create a very complex pattern on the <br />landscape, of which each is too small and variable to delinate by soil type or <br />estimate percent of inclusions. Other soils which share this landscape position ore <br />the Venable, Gapo, and Unnamed series 32. These soils are described in detail (see <br />descriptions of pedons listed on the next page). <br />Included in this complex are the following soils: <br />• <br />2.3-7 <br />
