Isle Royale National Park defines this landscape of Lake Superior, showcasing a complex archipelago of basaltic ridges and narrow harbors. This modern topographic survey highlights the northeastern tip of the island, where the Greenstone Ridge Trail and Rock Harbor Trail follow the natural spine and shoreline of the land. The mapping detail reveals the intricate sequence of islands protecting the main shore, including Porter Island, Merritt Island, and the many smaller outcrops like Gull Rock and Smith Island. The interaction of the lake and the land is most evident at Scoville Point and the long, sheltered reaches of Tobin Harbor and Snug Harbor. Further inland, features like Hidden Lake and Hog Island illustrate the varied terrain that has long served as a destination for wilderness exploration.
