West Elk Mine 2013 Annual Hydrology Report 29 <br />3.2.2 Springs above the B -Seam in the Box Canyon Area in the <br />North Fork of the Gunnison River Drainage Basin <br />3.2.2.1 Spring 11 -2 <br />Spring 11 -2 is located east of Box Canyon on a hillside on the south side of the NFGR <br />(Map 2). This spring is situated north of the Box Canyon mine panels area. It issues <br />from alluvium below a sandstone cliff, has seasonal flow, and is often dry in summer and <br />autumn. Hydrologic monitoring at this spring began in 2000. Slumping of the alluvium <br />at the spring location (since WY 2006) has caused the spring flow to periodically change <br />course and become dispersed across the hillside. <br />3.2.2.2 Spring 10 -1 <br />Spring 10 -1 is located on the east side of lower Box Canyon (Map 2). It is situated north <br />of the Box Canyon mine panels area and issues from alluvium on slopes tributary to the <br />NFGR. Flow is variable and does not follow a seasonal pattern. Hydrologic monitoring <br />at this spring began in 1999. <br />3.2.2.3 Spring E10 -2 <br />Spring E10 -2 is located on a hillside east of an unnamed drainage tributary to the NFGR <br />between Sylvester Gulch and Box Canyon (Map 2). This spring is situated in landslide <br />material below a fractured sandstone cliff north of the Box Canyon mine panels area. <br />Low flows were observed in WY 2005 and in the spring of WY 2006, but it has been <br />only a slow seep or dry for most of the period of record. Hydrologic monitoring at this <br />spring began in 1996. <br />3.2.2.4 Spring 15 -1 <br />Spring 15 -1 is located on the west side of an unnamed drainage tributary to the NFGR <br />between Sylvester Gulch and Box Canyon (Map 2). This spring is situated north of the <br />Box Canyon mine panels area. The spring issues from alluvium and water is present as a <br />slow seep only during peak flow months. Hydrologic monitoring at this spring began in <br />1996. <br />3.2.2.5 Spring G -la <br />Spring G -la is located in Sylvester Gulch on the west side of the drainage, north of the <br />northeast mine panels area (Map 2). It issues from alluvium and is seasonal with <br />moisture present only during periods of snow melt or peak flow. Hydrologic monitoring <br />at this spring began in 1983. <br />3.2.2.6 Spring G -20 <br />Spring G -20 is located in middle Sylvester Gulch on the east side of the drainage. It is <br />located east of the mine facilities and northwest of the Box Canyon mine panels area <br />(Map 2). It issues from alluvium or landslide material and disperses water through a <br />grassy area. Hydrologic monitoring at this spring began in 1979. <br />June 2014 HhdroGeo, Inc. <br />
