About this map

Isle Royale National Park emerges as a complex archipelago of elongated islands and deep harbors in this mid-1980s survey. The landscape is defined by the massive Greenstone Ridge which forms the island's high backbone, leading to prominent landmarks like Mount Franklin. The northeast end of the island is fractured into a series of narrow peninsulas and protected water bodies, including Five Finger Bay and Duncan Bay, creating a sheltered maritime environment.

Primitive infrastructure for wilderness travel is clearly marked, with various landing sites and remote stays such as Belle Isle Campground and Lane Cove Campground. The map details a labyrinth of smaller islands like Amygdaloid Island and Captain Kidd Island, separated by the Amygdaloid Channel. Genealogists and historians can trace the early park-era navigation routes and footpaths that connect coastal features like Suzys Cave and Tobin Cr.
