Fall 2015 Subsidence and Geologic Field Observations <br />South of Divide and Dry Fork Mining Areas <br />Figure 2. Fall 2015 view looking south of the same area of the MVB E5-16 pad as shown in Figure <br />1. Note the visible weathering and healing of the subsidence crack on the pad in the right lower <br />third of the image. <br />3.7 Photographic Observation Point 2 <br />This photographic comparison location (formerly Photographic Observation Point 13) was <br />established during the fall 2009 field visit along the traverse now known as Traverse F -F' <br />(approximately 500 feet southwest of point F). Overburden depth to the E -seam in this area is <br />about 680 feet. This location established two views; one looking northward toward the MVB E2- <br />27 pad and the other looking northeastward toward the MVB E2-30.5 pad. Comparison photos <br />obtained during our fall 2015 field visit revealed no noticeable changes. Mining of this portion of <br />E -seam Longwall Panel E2 occurred in late 2010 and early 2011. <br />3.8 Photographic Observation Point 3 <br />This photographic observation point was located on the now -reclaimed MVB E4-14 pad and had <br />been established during the spring 2013 field visit. This location had provided east -to -south views <br />up the Dry Fork drainage and of an unnamed tributary above E -seam Longwall Panels E4, E5, and <br />E6. Due to reclamation of the MVB E4-14 pad, no future photographic images are expected to be <br />obtained from this location. <br />831-032.797 Wright Water Engineers, Inc.
