2014 Map of Rock Harbor Lodge

About this map

Rock Harbor Lodge stands as the primary human landmark within the eastern reaches of Isle Royale National Park, situated at the edge of the deep waters of Lake Superior. This 2014 survey documents the intricate archipelago of the island's northeast end, where long, narrow peninsulas like Scoville Point and Blake Point reach out into the lake. The map reveals a complex aquatic landscape of sheltered waters such as Tobin Harbor and Duncan Bay, protected by a dense chain of barrier islands including Porter Island, Edwards Island, and Merritt Island. The terrain is characterized by the distinct linear ridges and geological formations like The Palisades, illustrating the unique volcanic archipelago structure of the region. This modern topographic record captures the wilderness character of the park, identifying navigational hazards like Five Foot Reef and Gull Rock alongside the remote outposts of the Keweenaw County shoreline.
