1985 Map of Grand Portage

USGS Topo · Published 1993

About this map

Isle Royale and the northern tip of Minnesota's North Shore define this mid-1980s topographic study of the international border waters. The landscape is dominated by the sprawling Isle Royale National Park, where the long spines of Greenstone Ridge and Minong Ridge run parallel to the Lake Superior shoreline. This era shows the isolated wilderness of the island preserved, featuring significant interior water bodies like Siskiwit Lake and Feldtmann Lake. Across the water, the Grand Portage Indian Reservation encompasses the rugged coastline near Grand Portage, a historic meeting place of cultures along Grand Portage Bay. The map traces the critical Ferry route connecting the mainland to Washington Harbor, while nautical navigation is anchored by the Rock of Ages Light standing watch over the reef-strewn waters between the mainland and the island chain.
