sediment deposition, and uses on these soils aze mostly passive (range, recreation, and <br />. wildlife habitat). The predomittant impediment to development on these soils is the <br />threat of flooding. They aze classified as VIw, soils with severe limitations generally <br />unsuitable for cultivation due to water (presence inhibitory to plant growth). <br />MINOR SOQ. UNITS <br />Absarokee-Work loam <br />These soils are found on moderately sloping to moderately steep locations on uplands <br />and sideslopes of drainage valleys. The Absazokee loam is a moderately deep, well- <br />drained soil originating from sandstone parent material. It ranges from 20 to 40 inches <br />in depth. Work foams are generally deeper than the Absarokee foams and may be <br />present in eolian material as well as in-place decomposed sandstone parent material. <br />Both soils have surface layers which aze foams approximately six inches thick. The <br />primary difference between these series is the depth of the subsoil horizon, the Work <br />series having a clay layer twice as thick as the Absazokee series. Native vegetation <br />may include grasses, sagebrush, oakbrush, and serviceberry. These soils aze primarily <br />used for grazing and wildlife habitat. <br />Cryochrepts-Cryoborolls-Rubble laud complex <br />These soils were characterized by the USFS within the Gunnison National Forest <br />portion of the SGFA. They aze found on mountain and canyon sideslopes and are <br />formed on residuum and colluvium. Cryochrepts and Cryoborolls aze moderately deep <br />to deep soils with moderate to rapid permeability and low water-holding capacity. <br />They are subject to rapid runoff and may have high erosion potential. Surface layers <br />aze generally stony foams, underlain by bedrock at approximately two feet. Native <br />vegetation is often a coniferous forest type. The major uses of these soils are wildlife <br />habitat and recreation. <br />Haploborolls-Ustochrepts-Rock outcrop complex <br />Soils of this complex are found on mountain, canyon, and ridge sidesiopes from 6200 <br />to 9700 feet. They are formed from residuum and colluvium with mixed origins. <br />These soils range from shallow to deep depending on location. Surface layers are <br />predominantly gravelly loam or clay loam. Subsurface layers are stony clay or sandy <br />clay foams. They are well-drained and subject to surface water erosion given their <br />textural makeup. Native vegetation is dominated by Gamble's oak, serviceberry, <br />Kentucky bluegrass, and big sagebrush. These soils are predominantly used for passive <br />recreation and wildlife habitat. Their land capability classification is VIlI, soils with <br />limitations nearly precluding their use for commercial crops. <br />• <br />-8- <br />
