Box 937 970-878-5628-OFFICE <br />Meeker, CO 81641 970-678-3730-FAX <br />Requested By: Russell Ranch General Partnership Date: December 16, 2005 <br />By: Ben Rogers <br />Assisted By: Alvin L. Jones Location: NW1/4, SW1/4, <br />District Conservationist Sec. 32, T1N; <br />R93 W, 6th PM <br />Situation: You requested an inventory of the existing soil and vegetation <br />for a proposed new gravel pit located in Section 32, T1N, R93W and <br />approximately 4 miles south east of Meeker, Colorado. You also requested <br />recommendations for reclamation of the site once mining is completed. <br />Information Provided: The site is presently in an undisturbed condition for <br />the most part, with an existing road that will be improved to provide access <br />to the site. Presently the site is primarily used for grazing by livestock <br />and wildlife. The intended post mining use of the site is for a residence. <br />SOILS - Four soil units have been mapped on this site. Following is a <br />description of each of these mapping units and any limitations or potential <br />hazards associated with each unit: <br />Soil Mapping Unit 11 - Borollic Calciorthids-Guben complex, 6 to 50 percent <br />slopes occurs on the lower slopes of the pit. This map unit occurs on <br />uplands and side of terraces. The Borollic Calciorthids portion of this <br />complex occurs primarily on terrace side slopes, which is the case at this <br />site. The Borollic Calciorthids are moderately deep to deep and well <br />drained. They formed in calcareous alluvial and glacial outwash. Typically <br />the surface layer is gravelly or cobbly loam, clay loam, or sandy loam 2 to 5 <br />inches thick. The underlying material ranges from a very gravelly loamy sand <br />or cobbly sandy loam to a very gravelly loamy sand or cobbly loamy sand. <br />Calcium carbonate content is generally more than 15 percent. Depth to soft <br />shale or sandstone is 20 to 60 inches or more. Permeability is moderately <br />rapid to rapid. Available water capacity is low. The effective rooting <br />depth is 20 to 60 inches. Runoff is medium to rapid, with a water erosion <br />hazard of high. <br />Soil Mapping Unit 38 - Guben loam, 0 to 3 percent slopes and Soil Mapping <br />Unit 39 - Guben loam, 3 to 8 percent slopes comprise the majority of the <br />proposed pit site. This is a deep, well drained soil on upland benches and <br />terrace edges. It formed in a thin eolian deposit over alluvium and glacial <br />outwash. Typically, the surface layer is a loam 6 inches thick. The upper <br />5 inches~of the subsoil is a loam. The lower 4 inches is a gravelly loam. <br />The substratum to a depth of 60 inches or more is a very gravelly loam and <br />very cobbly loam. The soil is calcareous throughout. Permeability is <br />moderate and the available water holding capacity is moderately low. <br />Effective rooting depth is 60 inches or more. Runoff is medium and the <br />hazard of water erosion is slight. <br />The Natural Resource Conservation Service works in partnership with the American People <br />to conserve and sustain nature) resources on private Lands.
