Top 5 Isle Royale National Park Facts

1. Isle Royale Had An Active Sea-Faring Trade

For someone who is a retired history teacher and lifelong history buff, for me one of the most fascinating of the Isle Royale National Park Facts has to do with ships which frequented this area.

According to the National Park Service, Native American copper hunters were probably the first navigators to risk the dangerous Lake Superior waters in order to travel to Isle Royale.

They most likely used the birch bark canoe, which was strong and versatile.

Isle Royale Was A Voyageurs Highway

During the 1600s, European-American missionaries, traders, and explorers who ventured to Isle Royale also used the canoe.

The famous route just north of lsle Royale, the “Voyageurs Highway,” was traveled by many canoes carrying trade goods from Mackinac or Montreal to get to Grand Portage.

Between the 1770s and the 1820s, furs were transported by the Northwest Company from Grand Portage (and later, Fort William) to Sault Sainte Marie in sailing ships.

The American Fur Company

It was not until 1837 when the American Fur Company established fishing posts on the island that large vessels and regular boat service began to arrive.

The American Fur Company had fishing operations at several sites on Isle Royale, with major warehouses located at Siskiwit Bay and Rock Harbor. These warehouses were visited by company-owned schooners that delivered supplies to the island and transported fish to Sault Sainte Marie.

After the Isle Royale American Fur Company fisheries closed in 1839, the island was not frequented by large sailing ships until the first copper mining rush in 1843, when the island saw an influx of ships transporting miners and supplies.

2. The Park Is Not Easily Accessible

Another of the more interesting Isle Royale National Park Facts, especially if you’re planning a visit there, has to do with its physical accessibility.

Isle Royale’s physical isolation and primitive wilderness challenged human use for centuries; ironically today it has become the Island’s main attraction.

Accessible only by boat or seaplane, visitors come to experience this island park through hiking its trails, paddling its inland waterways, exploring its rugged coast, or venturing into the depth of its shipwrecks.
