Spring 2014 Subsidence and Geologic Field Observations <br />South of Divide and Dry Fork Mining Areas (E -Seam) <br />Figure 19. Spring 2014 northward view of long <br />relatively continuous subsidence cracks located <br />on the east side of the MDW E4 -16 pad. The <br />nearly continuous nature of this crack is thought <br />to be the result of a brittle sandstone layer less <br />than on foot below the pad surface. <br />4.15 Photographic Observation Point 6 <br />Figure 20. Telephoto image of the same crack <br />observed in Figure 19. <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 ET <br />Figure 21 is the panoramic view from this location as obtained in spring 2013 that will serve as a <br />baseline against which future images will be compared to assess changes.
