Bowie No. 2 Mine (C- 1996 -083) MT- 4 Historic and current mining operations also exist in the general area. The Bowie No. 1 Mine is located west of the Bowie No. 2 Mine permit area. The Terror Creek Loadout is located to the south of the Bowie No. 2 Mine permit area, adjacent to the Unit Train Loadout. The reclaimed Blue Ribbon Mine is also located nearby along Hubbard Creek, as are outlying facilities associated with the Sanborn Creek /Elk Creek Mines. Historic coal mines located within and adjacent to the Bowie No. 2 permit boundary include the King Mine, the Gelwick Mine, the Blue Ribbon Mine and the Farmers' Mine. The former town site of Bowie is located within the Bowie No. 2 permit area. Geology - The Bowie No. 2 Mine permit area is located in the North Fork Valley of the Gunnison River, near the western margin of the Colorado portion of the Central Rocky Mountains. The elevation of the permit area ranges from about 6,000 feet above sea level to over 8,000 feet above sea level. The general area is situated along the southern flank of the Piceance Creek structural and sedimentary basin. The area is bounded by Larimide structural and physiographic features on the following sides: West Elk and Elk Mountains on the east; the Gunnison Uplift on the south; the Uncompahgre Uplift on the west - southwest; and the Grand Mesa - Piceance Basin on the north. The coal in the area is situated within Mesaverde formation which contains interbedded sandstones, mudstones, shales, siltstones and coal beds. The Mesaverde formation lies upon the Rollins Sandstone Member of the Iles formation and below the Wasatch formation. The coal bearing member of the Mesaverde formation locally contains up to nine (9) coal seams. These seams are located within a stratigraphic interval of approximately 500 to 600 feet above the Rollins Sandstone. These coal seams are, in ascending order, the A -Seam, the B -1 Seam, the B -2 Seam, the C -Seam, the D -1 Seam, the D -2 Seam, the E -1 Seam, the E -2 Seam and the F -Seam. The B -2 and D -2 Seams are mineable within the permit area. Hydrology - The permit and adjacent areas are generally bounded by three (3) perennial streams. These streams are Stevens Gulch, Hubbard Creek and the North Fork of the Gunnison River and are located in the west, east and south areas of the permit area, respectively. Tributary to the perennial streams are the following intermittent and ephemeral streams: Stephens Draw, Freeman Gulch, A- Gulch, B- Gulch, C- Gulch, D- Gulch, Dove Gulch and Sheep Corral Gulch. Terror Creek and West Terror Creek, perennial streams, run roughly north /south through the central permit area. There are numerous stock ponds located in the permit and adjacent areas. All of the ponds are manmade and store less than 20 acre -feet of water that is generally intended for domestic livestock use. The ponds collect spring season runoff and any available seep water. Groundwater in the area is located within the alluvial deposits along the North Fork of the Gunnison River and Hubbard and Terror Creeks, within the steep sloped colluvial deposits Page 4 of 22
