'''Isle Royale''' is an Islands of the Great Lakes island of the Great Lakes, located in the northwest of Lake Superior. The island and the surrounding smaller islands and waters make up Isle Royale National Park. It is 45 miles (74 km) long and 9 miles (14 km) wide, with an area of about 205 mi² (1 E8 m² 530 km²). It is United States territory (even though it is closer to the Canadian coastline) and is part of the state of Michigan.

The highest point on the island is Mount Desor at 1,394 foot (unit of length) feet (425 meter m), or about 800 feet (250 m) above lake level. Isle Royale was once the site of a lake trout and Coregonus whitefish fishery, a resort community, and unprofitable copper mines. It was also the site of crude copper mining by Native Americans of the United States Native Americans, centuries earlier. Today it has no permanent inhabitants, as the small community of largely Scandinavian fishermen were removed by the United States Park Service shortly after the Isle became a national park in mid-century. Isle Royale is within about 22 miles (35 km) of the Canada Canadian shore of the lake, near the city of Thunder Bay, Ontario, and about 50 miles (80 km) from the Michigan shore, on the Keweenaw Peninsula. There are seasonal passenger ferry services to the island from Grand Portage, Minnesota, Copper Harbor, Michigan Copper Harbor and Houghton, Michigan. There are no roads on the island. It is well known among ecology ecologists as the site of a long-term study of a predation predator-prey system, between moose and wolf wolves. Before the self-introduction of wolves to the island (crossing winter ice from Ontario), coyotes were the primary predators. Prior to that, caribou and lynx dominated. Other common mammals are red fox red foxes, American Beaver beavers, American Red Squirrel red squirrels, and snowshoe hares.
