Mww6 RAN EXHI&T D (CON7) agriculture, a community airport, greenhouses, dryland pasture, forested areas and rural residential. Access to the site is via an existing road in the northeast part of the site. Eventually a new access will be created along the west side as shown on the mining plan map. This access will be cut thru the embankment along County Road 60 into the old mining area so as to create a level road from the mine floor to the county road. GEOLOGIC SETL7NG The affected lands are located along the Fraser River on the Granby Mesa in a Pleistocene age, Slocum alluvial deposit. The sand and gravel encountered in this terrace deposit may consist of some glacial drift remnants from the last ice age. The deposit consists of colluvium and glacial till lying on top of Pierre Shale bedrock. The underlying shale beds strike at N87°W and dip 8° NE in the vicinity of the pit. Bedrock outcrops in the southwest corner of the property, where a spring occurs, concurrent with the elevation of the bedrock, at an approximate elevation of 8110 feet. Depths of gravel have been confirmed to an elevation of 8125 in the west-central part of the deposit and can be easily inferred to depths greater than the proposed ultimate pit depth. This type material is typically found in and around Granby between the Fraser and Colorado Rivers on the mesa. The quantity of course gravels and sand are approximately 80~ rock to 208 sand with some large boulder intermixed. It appears to be of fairly uniform depth across the property exceeding 100 feet deep in the northeast corner and slopes to the southwest corner where the ridge begins to drop into the river bottom. soars aNn ovExsrnenE2v See the soils and vegetation information for the soils report prepared by the Natural Resources Conservation Service regarding the soils on this site. The soil information prepared by the MRCS is not site specific, it describes in general terms the nature of the soils found at this site. This site consists predominately of the Quander stoney loam 15 to 558 slopes and Youga loam, 15 to 458 slopes. These soils are deep, well drained and occupy most swales, mountain fans and depressions at elevation ranging from 8000 to 9000 feet. Origins 4
