There seems to be an impeding layer or clay pan at 25 inches which has <br />hindered root growth below this point. Mottles are visible at 26 inches but they are <br />usually found closer to the surface. <br />Winevada Series <br />The Winevada Series consists of moderately deep to deep, well-drained, loamy <br />soil occurring on moderately To strongly sloping mid-slopes and ridges. The soils of <br />this series are formed in colluvium of shale and sandstone origin at elevations of 6,750 <br />and 7,600 feet. Permeability is moderate. These soils may be found in Sections 30 <br />and 31, T.SN R.85W. <br />Typically, The surface horizon consists of a dark brown loam 9 to 21 inches <br />thick, containing about 20 percent gravels. The subsoil is a brown or dark grayish <br />brown sandy clay loam or clay loam. This horizon extends from 32 to 57 inches. <br />Fractured sandstone is typically encountered between 20 and 40 inches depth. <br />Substratum material consists of yellowish brown or pale brown weathered sandstone. <br />WINEVADA TYPIC PEDON PROFILE !/ <br />• Loam 05-02-04-013 <br />A typical pedon (05-02-04-013) of the Winevada loam, 8 to IS percent slope, a <br />2.3-132 <br />
