Pictured Rocks National Lakeshore is located along the south shore of Lake Superior, between the communities of Munising and Grand Marais, in the north woods of Michigan's Upper Peninsula. It was authorized by Congress as the first national lakeshore on October 15, 1966, "to preserve for the benefit, inspiration, education, recreational use, and enjoyment of the public a significant portion of the diminishing shoreline of the United States and its related geographic and scientific features" (P.L. 89-668). The "diminishing shoreline" refers to public access to Great Lakes shores lost to private ownership. Formal establishment of the national lakeshore came on October 6, 1972.
