Fall 2017 Subsidence and Geologic Field Observations <br />South of Divide and Dry Fork Mining Areas <br />2017 field visit. Figure 10 shows these cracks as originally observed whereas Figure 11 shows the <br />same area as observed during our fall 2017 field visit. <br />Figure 10. Eastward view from spring 2017 of <br />two sub -parallel subsidence cracks along the <br />access road to the MVB E6-14 pad. The <br />orientation of these cracks is approximately <br />N60°E. <br />4.3.3 Location 4 <br />Figure 11. Fall 2017 view of the same area and <br />subsidence cracks shown in Figure 10. <br />Location 4 is MVB E6-14 pad, which is also the termination of Traverse C -C . -Subsidence cracks <br />associated with this pad and the access road leading onto the pad were first observed during the <br />spring 2017 field visit. Subsidence cracks on the pad were observed to have created small graben - <br />like structures where material between the parallel cracks had dropped in elevation (Figure 12). <br />Evidence of these subsidence features remained during our fall 2017 field visit but were greatly <br />diminished due to weathering (Figure 13). <br />831-032.799 Wright Water Engineers, Inc.
