About this map

Rock Harbor Lodge stands as the primary human touchpoint in this northeastern portion of Isle Royale National Park. The landscape is defined by the elongated, northeast-to-southwest ridges and valleys characteristic of the island, creating deep, protected water bodies like Tobin Harbor, Snug Harbor, and the expansive Duncan Bay. These finger-like harbors provide shelter from the open waters of Lake Superior, which surrounds the archipelago.

A dense network of small islands and rocky outcrops, including Porter Island, Edwards Island, and Bobs Island, guards the approach to the main harbor. The map traces the Stoll Trl leading out toward Scoville Point, a narrow peninsula that marks the transition from the protected inner channels to the exposed lake. This area, largely designated as the Isle Royale Wilderness, showcases the intersection of early park infrastructure at Park Place with a preserved maritime ecosystem.
