The fight over whether to allow copper-nickel mining near the Boundary Waters Canoe Area of northeastern Minnesota is shifting to St. Paul. The U.S. Forest Service is opening a new set of public meetings on its proposal to bar minerals exploration and development on more than 234,000 acres near the pristine wilderness for up to 20 years. The first meeting is Tuesday, July 25, 2017, in St. Paul. (AP Photo/Steve Karnowski, File)
