Fall 2013 Subsidence and Geologic Field Observations <br />South of Divide and Dry Fork Mining Areas (E -Seam) <br />3.0 TRAVERSES AND OBSERVATIONS IN THE SOD AND DRY FORK MINING <br />AREAS <br />A detailed discussion of observations associated with Traverses A -A' through J-J' (along with <br />accompanying Maps 1 and 2) is provided in this section. Several of the photographs obtained <br />during the fall 2013 field visit are included as figures in the text of this report. Where these images <br />have notable differences from previous photographs, the older image has been included for <br />comparison purposes. To reduce the overall size of this document, narrative text and photographs <br />for traverses where there have been no observable change are generally excluded. <br />Map I shows the outline of E -seam mining workings along with surface topography and other <br />surface features (including the named traverses). Map 2 shows the same area and detail (except <br />traverses) as Map 1 along with recently- active landslide and rockfall areas as delineated from aerial <br />photo research and field observations. <br />3.1 Traverses A -A' and B -B' <br />These traverses overlie portions of mined E -seam Longwall Panels E1, E2 and E3. As observed <br />during the spring 2013 field visit, many of the MDWs accessed via these traverses have been <br />reclaimed. Those MDWs that have not yet been reclaimed are the southernmost pads along <br />Traverse A -A' including E2- 51/52/54, E3 -51 and E3 -55. Note that in this report, a designation <br />similar to E2- 51/52/54 indicates one MDW pad containing three drill holes with separate <br />terminating points). <br />No subsidence - related features were observed along either of these traverses during our fall 2013 <br />field visit. <br />3.2 Traverse C -C' <br />This traverse follows the Dry Fork Road from Monument Dam (Minnesota Reservoir) eastward to <br />the where the road crosses Deep Creek (see Maps 1 and 2). Several portions of this traverse parallel <br />the Dry Fork itself. Portions of this traverse are above mined E -seam Longwall Panels E1 through <br />E4 as well as unmined portions of E -seam Longwall Panels E5 and E6.
