2019 Map of Passage Island

About this map

Isle Royale National Park encompasses the vast waters of Lake Superior in this specialized maritime and island survey. The map focuses on the northeastern reaches of the park, where a narrow strip of land is bisected by the Passage Island Trail. This isolated terrain is primarily defined by its nautical significance, situated along the shipping lanes of the Great Lakes. The map detail is concentrated within the township boundaries of t67n r32w and t68n r32w, documenting the specific elevation and coastline of this remote outpost. The absence of roads or urban development underscores the area's role as a protected wilderness and navigational landmark for mariners.
