About this map

Lake Superior dominates this late-1970s nautical and topographic landscape, marking the convergence of Wisconsin, Minnesota, and Michigan borders. The southern portion of the map is defined by the Apostle Islands, many of which are protected within the Apostle Islands National Lakeshore. These islands vary from the isolated Devils Island in the west to the elongated Outer Island in the east, which features the Outer Island Light at its northern tip and a Landing Strip further south.

Navigational landmarks and coastal features are emphasized, such as a Radio Tower on the northwestern islands and the sheltered waters of Aukad Bay. On the northern shore of the lake, Finland State Forest and Sugar Loaf Cove represent the Minnesota coastline in Cook Co. The map serves as a vital record of the territorial boundaries and maritime infrastructure before the era of modern digital navigation, highlighting the remote character of these Great Lakes archipelagos.
