RN8 -18- 11/7/23 <br />Mapping Unit – (X95F) (con’d.) <br /> Erosion Hazard: Slight from wind, moderate from water <br /> Other Features: Calcareous at 10 inches. Uses are restricted by slope, rock outcrops, and rock <br />fragments. Rock outcrops make up about 20 percent of the mapping unit. <br /> Capability Unit: VIIe non-irrigated <br /> Range Site: Loamy slopes <br /> <br />BOROLLS ROCK OUTCROP COMPLEX (104) <br />This complex is on north and west valley side slopes and ridges. The Borolls make up about 55 percent of <br />this complex and occupy lesser slopes. The rock outcrop part makes up about 35 percent of this complex <br />and occupies steeper slopes and ridgetops. <br /> The Borolls are shallow to deep, medium to fine textured, well drained soils over interbedded <br />sandstone and shale at a depth of 10-6 inches. They may be cobble or stone filled. <br /> The borolls portion has moderate to rapid permeability and the available water capacity ranges <br />from low to high. The effective rooting depth is from 10 to 60 inches or more. Erosion Hazard is slight to <br />moderate from wind and high from water. <br /> This complex is subject to slips and shows some “cat” steps. <br /> Capability Unit: VIIe non-irrigate, Boroll Part – BRUSHY LOAM <br /> Estimated pH: 6.6 – 7.4 <br /> Conductivity (mmhos/cm): <2 <br /> Depth Useable Topsoil: Highly variable <br />Torriorthents Rock Outcrop Complex (101) <br />This steep complex is on escarpment faces and valley side slopes. Torriorthent soils make up 50 percent <br />of the unit, occupying small colluvial fans and toe-slopes. Rock Outcrops make up 40 percent of the unit <br />and are on vertical ledges, ridgetops and steeper side slopes. <br />Torriorthents are course and medium textured stony and cobbly well drained soils over sandstone and <br />shale at 10-40 inches. Rock Outcrop is predominantly sandstone in narrow bands with colluvial stones <br />and boulders at the base. <br /> Capability Unit: VIIe non-irrigate, <br /> Estimated pH: 7.4-8.4 <br /> Conductivity (mmhos/cm): <2 <br /> Depth Useable Topsoil: 4 to 30 inches <br />
