Lake Superior dominates this aquatic borderland, where the remote maritime boundaries of the American Midwest meet the international line. This 2022 survey captures a unique geographic convergence point where Minnesota and Michigan share a water border north of the mainland. The southeastern corner of the map includes a portion of the waters surrounding Isle Royale National Park, reflecting the vast wilderness character of this region. To the north, the Canada-United States of America international boundary cuts across the open water, illustrating the modern cartographic definition of these high-latitude maritime limits.
