West Elk Mine 2014 Annual Hydrology Report 26 <br />the SOD mine panels area. The source of this spring appears to issue from sandstone <br />bedrock. This spring has been monitored since 2007. <br />3.2.1.15 Spring 2012-1 <br />Spring 2012-1 is located in an unnamed tributary to upper Deep Creek, which is tributary <br />to the North Fork (Map 2). This spring is located south of the southeast mine panels area <br />and east of the SOD mine panels area. The source of this spring appears to issue from <br />alluvium. The spring appears to have seasonal flow in response to spring runoff, and is <br />dry in the summer and fall months. This spring has been monitored since 2013. <br />3.2.1.16 Spring 2012-2 <br />Spring 2012-2 is located in an unnamed tributary to upper Deep Creek, which is tributary <br />to the North Fork (Map 2). This spring is located south of the southeast mine panels area <br />and east of the SOD mine panels area. The source of this spring appears to issue from <br />alluvium. The spring appears to have seasonal flow in response to spring runoff, and is <br />dry in the summer and fall months. This spring has been monitored since 2013. <br />3.2.1.17 Spring 2012-3 <br />Spring 2012-3 is located in an unnamed tributary to upper Deep Creek, which is tributary <br />to the North Fork (Map 2). This spring is located south of the southeast mine panels area <br />and east of the SOD mine panels area. The source of this spring appears to issue from <br />sandstone bedrock. The spring appears to have perennial flow, with the highest flows <br />occurring in the spring. This spring has been monitored since 2013. <br />3.2.1.18 Spring 2012-4 <br />Spring 2012-4 is located in an unnamed tributary to upper Deep Creek, which is tributary <br />to the North Fork (Map 2). This spring is located south of the southeast mine panels area <br />and east of the SOD mine panels area. The source of this spring appears to issue from <br />sandstone bedrock. Baseline monthly monitoring of Spring 2012-4 was conducted in <br />WY 2013. The spring appears to have perennial flow, and has been monitored since <br />2013. <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 North <br />Fork (Map 2). This spring is situated north of the Box Canyon mine panels area. It <br />issues from alluvium below a sandstone cliff, has seasonal flow, and is often dry or <br />nearly dry in summer and autumn. Hydrologic monitoring at this spring began in 2000. <br />Slumping of the alluvium at this location (since WY 2006) has caused the spring flow to <br />periodically change 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 />June 2015 HydroGeo, Inc. <br />
