Lake Superior dominates this nautical and terrestrial boundary study, capturing a critical intersection of international and state borders. The map documents the maritime corridor of the Grand Portage - Isle Royale Ferry, tracing its path across the open water toward Michigan’s island wilderness. This 2013 survey serves as a precise record of the Canada United States of America line as it cuts through the northern reaches of the lake. The convergence of the Minnesota Michigan state line with the international boundary highlights the complex jurisdictional nature of these waters. While primarily aquatic, the map provides essential context for the transit routes and political divisions that define the Pigeon Point offshore region.
