Western Colorado and reported in "Antiquities Inventory for • Sheridan Enterprises, Inc. Coal Exploration in the South Douglas Pass Area." The Antiquities Research Division studies located no cultural resources in their surveys of proposed access roads, drill hole locations, and small blocks of .land. The 1980 Grand River Institute survey covered 875 acres of the 6100 acres included in Sherdian Enterprises project area. All areas of potential surface disturbance such as proposed mine facilities and roads were intensively inventoried. In addition, other areas were selected for survey on the basis of slope (0-10 degrees) which are limited, but reflect the areas of greatest potential for past human utilization. These were also intensively surveyed. The Institute reported that in their opinion, "all portions of the project area which may have been conducive to prehistoric and/or historic occupations were subjected to a 100 percent pedestrian survey." The 1980 survey located two prehistoric sites, 5GF741, a rockshelter, and 5Gr742, a pictograph site, and a historic ranch complex, 5GF743. The 1983 Grand River Institute survey covered proposed roads and storage areas associated with the McLane and Munger Canyon mine plan/permit areas (about 80 .acres) and located one site, 5GF1147, a complex of prehistoric rock art panels and rockshelter campsites located at the mouth of Munger Canyon. Based on our and Bureau of Land Management~a (BLM) consultations th your office on the Munger and McClane Canyon Mines, it was ermined that sites 5GF743, 5GF326, and 5GF879 were not ~lgible for nomination to the National Register of Historic Places. Site 5GF741 will not be impacted by the project. Sites 5GF1147 and 5GF742 are eligible for nomination to the National Register. Additionally, the BLM received a "No Adverse Effect" determination based on a mitigation plan covering sites 5GF1147 and 5GF742 that might be impacted by the mining associated projects. Salt Creek Mining has agreed to undertake the mitigation plan if the road is constructed and the sites will be impacted. Specific to the McClane operation, site 5GF741 will not be impacted and will be subject to periodic monitoring as called for in the Munger Canyon mitigation plan. Sites 5GF742 and 5GF1147 lie outside of the proposed McClane Canyon permit area and will not be impacted by McClane Mine operations. All direct surface disturbance has taken place at the mine with the possible exception of a short haul road. The 700 foot haul road would join the proposed Munger Canyon haul road in NW1/4 of the SW1/4 of Section 21. The area of the haul road disturbance is covered by the previous inventories. Because of the room and pillar mining methods and operations orientation coupled with the nature and thickness of the •
