About this map

Lake Superior dominates this late-twentieth-century study of the northernmost reaches of Wisconsin and the Minnesota shoreline. The map centers on the northern archipelago of the Apostle Islands, specifically those within the Apostle Islands National Lakeshore such as Devils Island, Rocky Island, and the elongated Outer Island. These islands, situated within La Pointe Twp, reveal a landscape defined by maritime navigation and conservation rather than dense settlement.

A solitary radio tower and the Outer Island Light serve as vital landmarks for vessels navigating the open waters between the Wisconsin coast and the Minnesota border near Sugar Loaf Cove. The map captures the remote character of Ashland Co and Bayfield Co, where large tracts like Finland State Forest meet the cold waters of the lake, preserving a shoreline largely unchanged by modern industrial development.
