The Isle Royale National Park consists of the main island – the Royal Island – surrounded by more than 450 smaller islands in the archipelago between the Keweenaw Peninsula on the Upper Peninsula of Ontario and Michigan. These islands are a series of parallel ridges and atolls that rise above the lake and support the life of plants and animals, formed by geological uplifts and volcanic eruptions. Ojibwe, where he lived, called “Minong” (the place where blueberries were), and the Royal Island was designated as the International Biosphere Reserve in 1980. The ecosystems of dense northern conifers and northern hardwood forests are far from the mainland due to their limited but significant human disturbance. From the Royal Island you can see Thunder Bay in Ontario, but to reach these islands, visitors must have an airworthy boat or book a flight on a merchant or seaplane. Weather, wind and waves, fog and ice can be smashed on the island or near the island with almost no warning. The earliest occupations date back to about 6,500 years ago. These islands are closely related to the Grand Portage Ojibwe, the main inhabitant of the 20th century. They hunt, fish and collect berries and other foods, and they mine copper – an important trade commodity for thousands of years in the Midwestern United States today. There are approximately 1,500 prehistoric copper mines on the Royal Island, each with 1 to 100 pits.
