About this map

Isle Royale National Park dominates this terrain along the northern reaches of Michigan's wilderness. The landscape is defined by the parallel elevations of Greenstone Ridge and Minong Ridge, which run southwest to northeast across the island. Between these massive stone spines lie significant inland water bodies such as Siskiwit Lake, Hatchet Lake, and Lake Harvey.

The coastline along Lake Superior is jagged and peppered with protective coves and smaller landforms, including Todd Harbor, Florence Bay, and Pickett Bay. Dozens of small islands like Wilson Island, Green Isle, and Arch Island dot the nearshore waters. The map highlights the primitive infrastructure of the island, specifically the Greenstone Ridge Trail and Minong Ridge Trail, which provide the primary means of navigating this roadless archipelago. Geographic landmarks such as Mt Siskiwit and Twelve O'Clock Point serve as key orientation points for researchers and explorers of the island's interior.
