Spring 2014 Subsidence and Geologic Field Observations <br />South of Divide and Dry Fork Mininq Areas (E -Seam) <br />Figure 10. Fall 2013 easterly view of the access <br />road to MDW E4 -11 along the north side of Dry <br />Fork. Note the subsidence crack in the road <br />foreground. <br />4.7.3 Location 6 <br />Figure 11. Spring 2014 view of the same area <br />shown in Figure 10. Note the healing of the <br />foreground subsidence crack. <br />Several sub - parallel subsidence cracks were observed on the cut -slope above the access road as it <br />enters the MDW E4 -11 pad during the fall 2013 field visit (Map 1). Material along this cut -slope <br />appeared to be relatively loose as if it had been graded as opposed to being representative of an <br />exposed subsurface materials. The observed cracks (Figure 12) appeared to be more a function of <br />downslope movement of loose materials than a direct subsidence feature. Nonetheless, recent <br />mining in the area was thought to be a factor in the development of the observed features. Figure <br />13 shows this same location as observed during our spring 2014 field visit and the lack of any <br />remaining evidence of these same features. <br />831 - 032.795 Wright Water Engineers, Inc.
