Opis

Isle Royale National Park preserves a remarkable wilderness area in northwest Lake Superior near the Canadian border. Its isolation and severe climate keeps the island relatively free from human influences, creating an ideal natural laboratory to study the complexity of a relatively pristine ecosystem.
