The steep slopes of the stream valleys and the instability of the rock strata in the North Fork <br /> drainage basin has contributed to numerous landslides, mud flows and rock falls. These <br /> mass wasting features have been mapped by W.R. Junge of the Colorado Geological Survey <br /> and published as an open file report, entitled "Geologic Hazards, North Fork Gunnison River <br /> Valley, Delta and Gunnison Counties, Colorado." <br /> The primary land uses within the permit area are characterized as rangeland and woodland <br /> supporting big game (deer and elk) and livestock (cattle and sheep). Portions of the lease <br /> area are within the boundaries of Grand Mesa, Uncomprahgre and Gunnison National <br /> Forests. <br /> Cultural and Historic Resources - Rule 2.04.4 and 2.05.60) <br /> Cultural and historic resources are discussed in Section 2.04.4 of the permit application. <br /> Records from the Historic Buildings and Sites file of the Colorado Historical Society and the <br /> Archaeological Survey file of the Office of the State Archaeologist were reviewed for pre- <br /> viously recorded sites. No evidence was found indicating the existence of known sites in the <br /> vicinity of the mine. An archaeological reconnaissance was also conducted. Field studies, <br /> laboratory operations, and report preparation were completed by an archaeological team from <br /> Fort Lewis College in Durango, Colorado. This report can be found in Exhibit 10 of the <br /> permit application. No sites were found as a result of the field study. <br /> Additional surveys for Jumbo Mountain were completed by Western Cultural Resource <br /> Management, Inc. (WCRM, Inc.) during October and November 1993. Map 7A shows the <br /> areas surveyed during the field reconnaissance. A literature search was conducted by <br /> WCRM, Inc. in September 1993. That search identified 15 cultural resource reports. Those <br /> reports are listed in Exhibit 10A. Exhibit 10B contains the results of the survey. Exhibit 11 <br /> contains clearance documentation from the State Historic Preservation Officer. <br /> A Class 11 Cultural Resource Assessment was conducted by Metcalf Archeological <br /> Consultants, Inc., with the results of the assessment contained in a report dated January <br /> 1995. This report was submitted with Permit Revision No. 6 and is contained in <br /> Exhibit IOC. The State Historic Preservation Officer was contacted by the Division on <br /> August 21, 1995, and indicated concurrence with the submittal. <br /> Hydrologic Balance - Rules 2.04.5, 2.04.7. 2.05.3(4). 2.05.60) and 4.05 <br /> Ground water information can be found in Section 2.04.7 of the permit application. <br /> Additional information can be found on Map 34, which shows the location of the ground <br /> water monitoring stations and Map 35, which is a composite Barren member well water level <br /> and spring elevation map. <br /> A description of ground water occurrence and mining impacts on ground water within the <br /> permit and adjacent areas can be found in the "Probable Hydrologic Consequences of <br /> Mining" section of this document and the "Cumulative Hydrologic Impact Study" document <br /> for this mine area. <br /> The ground water systems relevant to mining activities in the region are the alluvial deposits <br /> associated with streams and the Mesaverde Formation.
