NRCS office.A single soil units is shown on the USDA map, on page 11 <br /> following this text.The photo map shows the surrounding vegetation <br /> features and soil types, not that much of the area has vegetative cover. <br /> This site is a series of east/west trending fingers covered by a terrace <br /> deposit of gravel and sand that is typical to this area. <br /> The 26- Eckley-Dix-Blakeland Complex, 6 to 20%slopes siol series <br /> covers the entire 30 plus acres of this mine site. The general soils <br /> description indicates that this soil is well drained soil found on gravel <br /> breaks in northeastern Weld County.The upper most horizon is 0 to 8 <br /> inches of a sandy clay loam that will be usable as topsoil. On this site <br /> the topsoil coverage ranges from 0 to 2 inches with approimately 80% <br /> of the area being exposed sand and gravel where there is no topsoil <br /> or growth medium. We will salvage all topsoil on the site for use <br /> during reclamation. Underlying the topsoil is a 25 to 50 foot lens of <br /> gravelly sand that we plan to mine.The deposit lies in the upper part <br /> of the Ogallala Formation that has unspecified depth. We plan to mine <br /> the upper 50 feet leaving the mine floor with a gentle slope from the <br /> west toe excavation slope to the east to facilitate drainage. <br /> Page 10 <br />
