Fall 2017 Subsidence and Geologic Field Observations <br />South of Divide and Dry Fork Mininq Areas <br />Figure 3. Southward view (fall 2017) of the <br />same area, from the same general location, as <br />shown in Figure 1. Note that the road has been <br />regraded and there remains little or no evidence <br />of the subsidence features observed during the <br />spring 2017 field visit. <br />4.3 Traverse C -C' <br />Figure 4. Southward view (fall 2017) of the <br />same area, from the same general location, as <br />shown in Figure 2. <br />Traverse C -C on7iginates in the Deer Creek drainage adjacent to the lower stock pond (P74) and <br />proceeds eastward, trending north and then south, over mined E -seam Longwall Panels E2, E3, <br />E4, E5, and E6 (see Map 1) as well as portions of unmined E -seam Longwall Panel E7. E -seam <br />overburden depths along this traverse vary from 450 feet in the Deer Creek drainage to <br />approximately 900 feet over mined E -seam Longwall Panels E4 and E5. <br />Photographs from east- and west -facing overview locations were obtained from designated <br />locations along this traverse as in previous visits. Photographic comparisons to previous images <br />found no substantive differences. <br />831-032.799 Wright Water Engineers, Inc. Page 14 <br />February 2018 <br />
