Spring 2014 Subsidence and Geologic Field Observations <br />South of Divide and Dry Fork Mining Areas (E -Seam) <br />Figure 13. Spring 2014 view of the same area depicted in Figure 12. Healing and weathering <br />have eliminated nearly all evidence of the features observed in fall 2014. <br />4.8 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 MDW E2- <br />27 pad and the other looking northeastward toward the MDW E2 -30.5 pad. Comparison photos <br />obtained during our spring 2014 field visit revealed no noticeable changes. Mining of this portion <br />of E -seam Longwall Panel E2 occurred in late 2010 and early 2011. <br />4.9 Photographic Observation Point 3 <br />This photographic observation point is located on the MDW E4 -14 pad and established during the <br />spring 2013 field visit. This location provides views to the east (up the Dry Fork drainage) and <br />south (up an unnamed tributary above mined portions of E -seam Longwall Panel E4 and unmined <br />831 - 032.795 Wright Water Engineers, Inc.
