History

Long before Europeans arrived in North America, Native Americans were mining copper on Isle Royale. Using hand-held beach cobbles, they hammered out chunks of pure copper from the hard bedrock. Archeologists have excavated shallow mining pits, some dating back 4,500 years. It is believed these early miners were most active here from 800 to 1600 B.C.

The late 1700s saw the advent of commercial fishing on Isle Royale. By the 18th and 19th century, a number of different industries came to the island, including modern copper mining. At that time, large areas were burned and logged and settlements developed. The American Fur Company used the ancient method of gill netting to take whitefish, lake trout, and siskiwit. The tradition has been handed down through fishermen's families. By the 1840s, the only Native American encampments that miners encountered were a maple sugaring camp on Sugar Mountain and a seasonal fishing camp on Grace Island. Early this century, Isle Royale became popular for summer homes, excursions and as a wilderness retreat. Detroit journalist Albert Stoll, namesake of the Stoll Trail, sparked the fight for the national park, established in 1940.

Aquatic environments abound as nearly 80 percent of the national park is underwater in the form of shallow warm-water ponds, streams, rivers, and the deep, cold, waters of Lake Superior. Commercial fishing has been one of the mainstays of the island economy, beginning as early as 1800. The major commercial species are lake trout, whitefish, and herring. Most commercial fishing enterprises closed by the mid-20th century, however, and are now preserved at the historic Edisen Fishery.

Today, species sought by sport fishermen are lake, brook, and rainbow trout; northern pike; walleye; and the yellow perch. Spring and fall produce the biggest catches, but fishing is good throughout the season.

Isle Royale is an island of superlatives in wilderness and beauty. You will find your own superlatives here as you meet the island on its own terms: fishing, boating, hiking, backpacking, taking a guided interpretive walk or hike, or just relaxing.
