About this map

Isle Royale National Park occupies this southwestern corner of the island, where the landscape is defined by the prominent Feldtmann Ridge overlooking the interior waters of Feldtmann Lake. This 2023 survey by the U.S. Geological Survey illustrates the transition from the rocky coastline of Lake Superior to the protected wilderness of the island's interior.

A network of footpaths, including the Feldtmann Lake Trl and the Rainbow Cove Trl, connects the island's features, leading travelers from the shelter of Grace Harbor down toward the sweeping shoreline of Rainbow Cove. The map details coastal landmarks such as Cumberland Point and Middle Point, as well as the drainage of the Big Siskiwit River into the surrounding cold waters. This area remains part of the designated Isle Royale Wilderness, emphasizing its role as a sanctuary for natural study and preservation.
