About this map

Isle Royale National Park dominates this mid-1980s mid-scale survey, showing the wilderness archipelago of Keweenaw County isolated in the waters of Lake Superior. The topography is defined by the parallel elevations of Greenstone Ridge and Minong Ridge, which create a landscape of elongated inland water bodies such as Siskiwit Lake and Sargent Lake. These ridges also form the sheltered harbors of Rock Harbor and Todd Harbor that characterize the coastline.

Administrative and logistical points are marked at Park Headquarters on Mott Island and the Ranger Station near McCargoe Cove. The map also reveals the island's industrial past with a Mine site near Mine Point and several named topographic peaks like Ishpeming Point and Mount Desor. The proximity to Ontario is clear, with the international boundary and Sibley Provincial Park appearing to the north across the lake.
