Lake Superior dominates this maritime survey, illustrating the isolated southwestern reaches of Isle Royale. The map depicts the rocky outcroppings and small islands that define the archipelago's fringes, including Washington Island and the smaller Bottle Island nearby. Most of the land area is strictly preserved as part of the Isle Royale National Park and the federally designated Isle Royale Wilderness, providing a modern record of this protected island ecosystem. Significant navigational markers such as North Rock and South Rock are identified, highlighting the submerged hazards and geological features that characterize the cold waters of this Lake Superior boundary area.
