Greenstone Ridge forms the backbone of this archipelago within Isle Royale National Park, where a complex network of islands and narrow channels defines the Lake Superior shoreline. The map documents a wilderness landscape managed for conservation, featuring prominent elevations like Mt Ojibway and Mt Saginaw. Along the protected waters of Rock Harbor, small islands such as Mott Island and East Caribou Island cluster near the Middle Islands Passage. The presence of Cem Island and the Daisy Farm Trl suggests a history of human activity and early settlement patterns that predated the wilderness designation. From the depths of Moskey Basin to the landmark Caribou Arch, the map details a unique island geography shaped by prehistoric geology and modern preservation efforts.
