Quetico - Superior
A wilderness area of unequalled beauty, Quetico - Superior has long been a focal point for recreationists and conservationists. At the turn of the century, public concern about outdoor recreation and wilderness protection in the Rainy Lake watershed led to the designation in 1909 of the Superior National Forest, the Minnesota Game Reserve and the Quetico Forest Reserve. Four years later Quetico became a provincial park. Since that time the governments of the United States, Minnesota and Ontario have worked co-operatively to ensure the preservation of Quetico - Superior as one of the world's largest international wilderness areas.
