Pictured Rocks National Lakeshore extends 40 miles along Lake Superior from Grand Marais to Munising. The Pictured Rocks cliffs rise to 200 feet above the lake, a spectacular example of the erosive action of waves, wind and ice. The Grand Sable Dunes expose part of a glacial deposit up to 200 feet high. Five square miles of dunes that once edged an ancient predecessor of Lake Superior top the banks by another 100 feet. The area includes Beaver Basin Wilderness, an 11,740-acre area recently granted protection from development with the Omnibus Public Land Management Act of 2009. Learn More...
