Saving Quetico Superior
註釋Encompassing the Boundary Waters Canoe Area of Superior National Forest, Voyageurs National Park, and Grand Portage National Monument in Minnesota and Quetico Provincial Park in Ontario, the Quetico-Superior is the only region of its kind in the U.S. and Canada. This book tells the story of the long campaign to secure and preserve it for posterity and also illustrates the development of an American idea -- wilderness preservation.
