Isle Royale Wilderness
The Ojibwe who have visited the island for more than 4,500 years called Isle Royale "Minong", the good place. French trappers gave the 45-mile-long, nine-mile-wide Isle Royale its regal name. Located in the northern, surging waters of Lake Superior, 99% of Isle Royale National Park has been designated Wilderness. The largest island in the largest freshwater lake in North America, it is also by far the state's largest Wilderness area. Created by flowing lava, flattened and smoothed by glaciation and subsequent erosion, the island contains more than 100 lakes and small ponds; in fact, water covers more of the surface than dry land when you include the waters of Lake Superior where the park boundary extends 4.5 miles out.
