Rock Creek Mine

Case Overview

The Fish and Wildlife Service rewrote a biological opinion that originally said that a mine proposed in the Cabinet Mountains in Montana could wipe out grizzly bears and bull trout there — the new opinion says the mine poses no threat. A district court has now ruled that opinion illegal too, halting the mine for now.
