Federal Agency LandownerBureau of Land Management
In 2006, the US Bureau of Land Management closured and reclaimed 10 abandoned uranium mines including: Marie, Robert’s Incline, Lisbon Point East, CM&M Pit, CM&M West, Dandy Southeast, Dandy Central, Dandy East, Dandy West Upper, and Dandy West Lower located in the Red Pryor Mountains of south central Montana. These mines posed physical safety as well as recreational exposure hazards prior to reclamation. BLM removed ore for reprocessing, re-graded waste rock/overburden piles, and closed mine entrances and fitted them with bat gates to maintain bat populations. Waste rock and overburden piles were uniquely re-graded to discourage recreational use on the piles.
