2017 Map of Passage Island OE N

About this map

Isle Royale National Park defines the southern portion of this maritime survey, where the terrestrial reaches of Keweenaw Co meet the open expanse of Lake Superior. The map is characterized by the international boundary between Michigan and Canada, tracing a diagonal path through the northern waters of the lake. This border region highlights the remote proximity of the Michigan wilderness to its northern neighbor, focusing on the aquatic environment rather than terrestrial infrastructure. The inclusion of public land survey identifiers such as t68n r32w and t68n r31w provides a precise coordinate framework for this northernmost section of the park, making it a critical reference for understanding the jurisdictional reach of Michigan's island territory.
