The Boundary Waters Canoe Area of northern Minnesota was geologically carved by glaciers and is home of more than 1100 lakes. This 1.1million acre wilderness tugs at the hearts of so many that it is the most heavily visited Wilderness Area in the United States. It was designated as a Wilderness in 1965 and is much the same today as it was then. A combination of the BWCA, Voyageurs National Park, and Ontario's Quetico La Verendrye Provincial Parks make up a larger area of contiguous wilderness lakes and forests called the Boundary Waters.
Today foreign mining companies have plans to build toxic sulfide-ore mines in the drainage basins of the Boundary Waters. If these mines go into operation, the acid runoff from these mines could cause irreparable damage to the entire wilderness complex.
