About this map

Isle Royale National Park preserves a maritime wilderness at the southwestern end of the archipelago, where the land breaks into a series of jagged peninsulas and sheltered waters. The topography is defined by the prominent Feldtmann Ridge, which runs parallel to the coast and overlooks Feldtmann Lake. This interior lake is separated from the open waters of Lake Superior by a narrow strip of land, creating a distinct hydrological environment.

Navigation and access are dictated by the island’s natural geography, with the Feldtmann Lake Trail and Rainbow Cove Trail providing the primary overland routes. The coastline is marked by distinctive landmarks such as Washington Island near Grace Harbor, and the sharp protrusion of The Head to the south. The presence of the Big Siskiwit River in the northeast corner of the sheet indicates the drainage patterns that feed into the larger bays like Rainbow Cove.
