About this map

Isle Royale National Park dominates this mid-1980s topography, illustrating the southern shoreline of the island where the wilderness meets the cold waters of Lake Superior. The landscape is defined by the prominent Feldtmann Ridge, which runs parallel to the coast, rising above the surrounding timber and wetlands. At its height, the Feldtmann Lookout Tower serves as a critical vantage point for monitoring the island's interior.

Along the coast, the map details the transition from high ridges to the shoreline at Attwood Beach and the precarious navigation around McCormick Reef. Inland, the drainage of the Big Siskiwit River and the isolated Lake Halloran provide a look at the island's interior hydrology. This survey reflects the park's character after decades of federal management, preserving the network of trails and primitive landmarks that define this remote section of Keweenaw County.
