1963 Map of Rocky Island

USGS Topo · Published 1965

About this map

Apostle Islands emerge from the deep waters of Lake Superior in this mid-century maritime survey within La Pointe Twp. The map documents a cluster of landmasses including Devils Island, which features a prominent Light and Radio Tower at its northern point to guide ships through the nearby Devils Island Shoal. This era reflects a period of limited development on these remote outposts, with a solitary Landing Strip on South Twin Island providing one of the few modern transport links to the mainland. Navigational soundings throughout the lake reveal the submerged topography surrounding Bear Island, Rocky Island, and Cat Island, highlighting the complex underwater environment that has long challenged Lake Superior mariners. Other named features like Ironwood Island and Otter Island appear in their mid-twentieth-century state, showing the geographic relationships between these isolated landforms before modern park designations.
