"In the northwestern portion of powerful Lake Superior exists a unique and remote island archipelago. Isle Royale National Park preserves 132,018 acres of land-based wilderness that was federally designated October 20, 1976 . The park consists of one large island surrounded by about 400 smaller islands, it encompasses a total area of 850 square miles including submerged land which extends four and a half miles out into the largest fresh water lake in the world. Due to Isle Royale's biological and ecological uniqueness, it was designated an International Biosphere Reserve in 1980."

Isle Royale National Park is significant because:

• This maritime park encompasses a remote and primitive wilderness archipelago (island group), isolated by the size and power of Lake Superior.
• Isle Royale is world renowned for its long-term wolf/moose predator/prey study. The park offers outstanding possibilities for research in a remote, relatively simple ecosystem where direct human influences are limited.
• Park waters contain the most productive native fishery and genetically diverse trout populations in Lake Superior.
