Each of the cracks were still present during our fall 2018 field visit with the exception <br /> of the one located on the north end of the pad, which could not be identified. The small exposed <br /> section of sandstone on the north side of the pad showed signs of continued rockfall as shown on <br /> Figure 5. <br /> Additional cracks were observed at various location on or near the pad with the greatest in length <br /> and depth being located west of the access road to the E7-10 MVB pad (Figure 6). <br /> 831-032.900 Wright Water Engineers, Inc.
