Fall 2013 Subsidence and Geologic Field Observations <br />South of Divide and Dry Fork Mining Areas (E -Seam) <br />revealed several non - continuous but subparallel cracks trending approximately N10 °W through <br />the pad. The longer of the cracks was readily apparent where the road enters the pad from the <br />southwest during the spring 2013 visit but significantly less obvious during our fall 2013 field visit <br />(Figure 15). <br />+ r <br />�y fi <br />I <br />Figure 15. Spring 2013 southward view of the MDW E3 -06 pad showing the longest of the <br />subparallel subsidence cracks (left). A fall 2013 view of the same area finds this same crack <br />significantly weathered and less obvious (right). <br />3.15 Photographic Observation Point 6 <br />This photographic observation location was established during the spring 2013 field visit as a <br />baseline for assessing potential changes to the landscape associated with E -seam longwall mining <br />within and west of the Deer Creek drainage. <br />This vantage point allows a view of the Deer Creek drainage from its headwater region <br />downstream along most of the drainage to near its confluence with Dry Fork. Views from this <br />location present the topography over the western end of E -seam Longwall Panels E3 through E7. <br />Longwall mining had not occurred beneath this area between our spring and fall 2013 field visits. <br />831 - 032.795 Wright Water Engineers, Inc.
