aeolian origin about 8 to 10 inches thick. A cobbly loam occurs at about 20 inches <br />• overlying a very gravelly loamy sand which extends to about 5 feet. <br />Presently this soil is used for cultivated dryland wheat production, rangeland and <br />grazing. Vegetation is Artemisia tridentate big sage. <br />Permeability is rapid. Wind erodibility is high withouT sufficient ground cover. <br />Depth to ground water is greater than 5 feet. Effective rooting depth is less than <br />25 inches. Stoniness class is 0. <br />Land capability unit is Vlle. <br />MAP UNIT HaD: HANDRAN STONY LOAM, IS TO 30 PERCENT SLOPE <br />This deep to very deep, well-drained, loamy soil formed in old alluvial gravels <br />on terraces and steep escarpments. The loamy soil overlies sandstone with cobbles <br />at about 2 feet. This mapping unit occurs on the steeper slopes west of Trout Creek, <br />east I/4 Section 25 and 36, T.SN R.86W at 6,800 to 7,200 feet elevation. <br />The soil profile representative of this mapping unit is similar to the Handran <br />series description (pedan/i 05-03-10-034) except that below 30 inches, a horizon of <br />• varied colored sands and gravels occurs overlying standing water. Included in this <br />mapping unit are small areas of rock outcrops on the steeper parts of the slopes. <br />Inclusions make up 10 percent of the mapping unit. <br />Presently this soil supports vegetation mainly used for livestock grazing, <br />rangeland and wildlife habitat. Vegetation consists mainly of Artemisia tridentate <br />big sage; it is less productive near rockier areas. <br />Permeability is rapid. Ground water is ~at about 5 feet. Erosion hazard is high <br />from wind, moderate from water. Stoniness class is 3. Effective rooting depth is <br />about 25 inches. <br />The land capability unit is Vlle due to the slope and stoniness. <br />MAP UNIT HaF: HANDRAN STONY LOAM, GREATER THAN 65 <br />PERCENT SLOPE <br />This deep to very deep, well-drained, loamy soil is formed in old alluvial gravels <br />on very steep to extremely steep terraces and escarpments. The loamy soils overlie <br />cobbles at about 2 feet. This mapping unit occurs in east I/q Sections 25 and 36, <br />• T.SN R.85W, west of Trout Creek at 6,800 to 7,000 feet elevation. <br />The soil profile in this mapping unit does not vary significantly from the series <br />2.3-10 <br />
