MAY-11-2005 WED 02:03 PM dept of lot BTU Empire, 8al*le S Mine, p~. 4 FAX N0. 3038441545 Mrs. Binns and Mr.. Barker walked the canyon area as well from the above location and observed a land slump at N 40 26 26.4 W 107 39 46.8 that Mr. Barker had discussed with us eazlier; and also two presumed small surface subsidence .features that have been regraded and repaired. Sandstone outcrop with very noticeable cracking observed at N 40 26 005 W 107 39 922 at 6,486 ft., above the 14` left area. Tlus area is 30 to 50 feet from vertical cliff faces of these same sandstone outcrops. Naturally occurring sandstone joints, oriented parallel to the obvious crack, exist in this same sandstone formation. This sandstone crack is 9 to 12 feet deep in spots, 4 to 6 inches wide, running 30 to 50 ft. minimum, and characteristic of surface subsidence features near outcropping sandstone units. Anotherfeature, asinkholeadjacent to the roadway at N 40 26 092 W 107 39 905 at 6,545 ft., was found along a crack line that includes a hole in the roadway reportedly filled with roelcs by Mr. Barker last year. This eraclc extends uphill west from the sinkholo for up to 100 ft. minimum. This crack is very obvious, and just uphill and almost pazallel to this 1$` crack, is another very obvious sandstone crack with vertical fracturing typical of sandstone unit subsidence, showing down througb the sandstone outcrop at N 40 26 104 W 107 39 924 at 6,570 ft. These surface (cracked sandstone outcrop units) features are almost certainly subsidence related in this area. Next stop was a BLM survey marlter at N 40 26 068 W 107 40 081 at 6,675 ft. installed this year by Dave Ginther, BLM. This is between Sec 34 and Sec. 25, Next stop was at N 40 26 039 W 107 40 41.1 at 6,975 ft. where we split into 2 groups to again walk affected areas above underground mine workings. We located ourselves on maps, and looked for subsidence features, No subsidence features noted in this area by either group. Next stop was at the cell phone tower at N 40 25 861 W 107 40 536 where we walked aff'ect'ed areas, but did not observe any subsidence features. Noted.another BLM survey mazker at N 40 25 371 W 10? 40 709 at 6,865 ft., with no subsidence noted in this area. Next stop at approximately the western extent of coal extraction at N 40 25 587 W 107 40 709 at 6,880 ft., where we found no evidence of surface subsidence features. The last stop of the inspection was at a possible drill pad location, adjacent to the road st N 40 26 080 W 107 40 209 at 6,937 ft. This area is vegetated and stable. This concluded the inspection.
