Lake Superior surrounds the northern reaches of the island wilderness documented in this 2014 survey. Much of the sheet is occupied by the open waters of the lake, yet the northern edge reveals the complex shoreline of Isle Royale, specifically within the boundaries of Isle Royale National Park. Here, the inland waters of Siskiwit Lake are visible, separated from the Great Lake by narrow strips of land. To the west, the underwater geography is marked by Glenlyon Shoal, a feature critical for navigation in these treacherous northern waters. The map provides a clear look at the protected status and remote character of this island chain, showing the intersection of Township 65 North and Range 35 West amidst the aquatic expanse.
