These features described above ail appear to be located on BTU Empire surface land ownership. This area described above, generally north and west of the tower location out to downhill slope breaks, needs to be evaluated for possible.temediation of slip & fall hazazds associated with these small openings. llisturbing active anima) burrows should be avoided to the extant possible, unless they represent a serious slip and fall hazard. These openings have created excellent habitat for badger sized mammals and smaller. We continued to inspect downhill west, and southwest of the tower location looking for subsidence features. Land ownership here includes $TU Empire, State of Colorado, and Mr. $arlcer. Steel casing from presumably an abandoned monitoring well was located at N 40 26 06 W 107 39 16 at 6,277 :Ct. The casing appears to be sealed at 14.5 feet below ground level. USOS-1918 (or 1908) section corner at N 40 26 06 W 106 39 ] 6 at 6,287 ft. with EPl? Associates Survey markers from recent (2-3 years) surveys. We observed a small sinkhole 2 to 3 feet deep at this location, which could be associated with a former exploration drill pad, and this location is just downhill and southwest of the EPP survey markers. We inspected the .remainder of this area and saw no really obvious surface subsidence features, We attempted to reach additional affected areas west of the Yampa River on the afternoon of November 18, but decided to wait until the next morning due to time of day. Tltis concluded the inspection on November 18. On November 19 we inspected the affected surface areas above Eagle 5 6i iA Mines proposed for release, west of the Yampa River. We were able to drive onto and through Mr. Banker's property, and made stops and observations at the following (in order observed): P. 07 North end of affected area between 2"a west mains, sod 1 ~` north at N 40 26 275 W 107 39 985 at 6,517 ft.. We walked this area in orientation above the mine Workings looking for subsidence features. We found no obvious surface subsidence features here.
