"Coteau's mining plan does take steps to balance cultural resources against the rights of the minerals owners to have their coal mined. Coteau will mine around some 15 cultural sites, which include multiple features and are eligible for listing on the National Historic Register.
Once reclamation is completed around those sites -- years from now -- the approximate 1,700 acres will be preserved in a first-ever perpetual land trust. Cultural features that will be preserved include 327 stone rings, 93 stone cairns, 11 stone alignments, a turtle effigy and an unmarked burial." [Click here]
