Exhibill <br />. MANVEL SILT LOAM, 1-5% SLOPES <br />This is a deep, well-drained soil found on alluvial fans and formed in silty <br />colluviaUalluvial material derived from limestone. Permeability is moderately slow, and <br />the available water capacity is high. Runoff is moderate and the shrink-swell potential is <br />low. This soil has moderate water and wind erosion hazards. The native vegetation is <br />mainly plains grasses. <br />Manvel silt loam, 1-5% slopes, has been assigned to land capability class IIIe (irrigated), <br />indicating severe limitations that reduce the choice of plants, require special conservation <br />practices, or both. It is also assigned to land capability class VIe (non-irrigated), <br />indicating severe limitations that make it generally unsuited to cultivation and restrict its <br />use lazgely to pasture, range, woodland, or wildlife habitat. The "e" sub-class indicates <br />that the main limitation of this soil is risk of erosion. <br />PENROSE-MINNEQUA COMPLEX, 1-15% SLOPES <br />This complex is made up of about 60 percent Penrose channery loam. The balance is <br />comprised of equal parts of Manvel silt loam and Minnequa loam. <br />Penrose channery loam is a shallow, somewhat excessively drained soil formed on <br />upland hills and ridges in loamy residuum weathered from limestone. Permeability is <br />• moderate and the available water capacity is very low. Runoff is rapid and the shrink- <br />swell potential is low. This soil has a low to moderate water erosion hazard and a low <br />wind erosion hazard. Chazacteristics of the Manvel silt loam portion of this complex are <br />described in the previous section. <br />Minnequa loam is a moderately deep, well-drained soil formed on uplands in silty <br />residuum weathered from limestone. Permeability and available water capacity are <br />moderate. Runoff is medium and the shrink-swell potential is low. This soil has a low to <br />moderate water erosion hazard and a low wind erosion hazard. The native vegetation is <br />mainly plains grasses with some sagebrush andjuniper. <br />The Penrose-Minnequa complex, 1-15% slopes has been assigned to land capability class <br />VIIs, indicating very severe limitations that make it unsuited to cultivation and restrict its <br />use largely to pasture, range, woodland, or wildlife habitat. The "s" subclass of this <br />complex indicates that these soils aze limited mainly because they aze shallow, droughty, <br />or stony. <br />PENROSE-ROCK OUTCROP COMPLEX, 25-65% SLOPES <br />This complex is found at the edge of the escarpment on the western edge of the <br />Limestone Mine site. It is made up. of about 50 percent Penrose channery loam and 30 <br />percent rock outcrop of limestone and interbedded shale.
