Fall 2014 Subsidence and Geologic Field Observations <br />South of Divide and Dry Fork Mining Areas <br />Lastly, a native slope failure scar was photographed north of the MDW E5 -14 pad (see Map 2) <br />approximately 200 feet north of the headgate entries of mined E -seam Longwall Panel E4. This <br />feature is not observable from the MDW E5 -14 pad but rather by looking southwesterly from the <br />MDW E4 -11 pad located on Traverse F -F' (see Figure 10). Review of available aerial photography <br />from Google Earth finds that this slope failure predates September 1999 and, as such, predates <br />mining activities in this area. This location and feature will be observed during the next several <br />visits to assess potential change as mining of E -seam Longwall Panel E5 passes beneath the area <br />to the south. <br />Figure 10. Southwestward view of native landslide feature (yellow arrow) as observed from the <br />MDW E4 -11 pad. The feature occurred sometime prior to 1999 (and prior to mining activities) <br />based on available aerial photography reviewed and is located 200 feet north of the headgate <br />entries of mined E -seam Longwall Panels E4. <br />3.15.1 Location 3 <br />A relatively continuous feature was again observed along the cut slope boundary south of the <br />MDW E5 -9/10 pad (see Figure 11). This feature was first observed during the spring 2014 field <br />visit and before mining occurred beneath this area suggesting that it is the result of mass - gravity <br />movement of the unconsolidated material placed against the cut slope on the south side of the pad. <br />831 - 032.796 Wright Water Engineers, Inc.
