About this map

Devils Island stands at the northernmost reaches of this Lake Superior survey, defined by its isolated Light and Radio Tower. Part of the Apostle Islands chain within La Pointe Twp, the landscape is a maritime collection of landforms shaped by the lake's currents, including Rocky Island, South Twin Island, and the northern tips of Bear Island and Otter Island.

Insights into mid-century island utility are visible on South Twin Island, which features a small Landing Strip, likely serving as a critical connection to the mainland before modern infrastructure reached these outposts. Surrounding waters are marked by hazards like Devils Island Shoal, while the smaller Ironwood Island sits to the southeast. This map captures the remote character of Ashland County's archipelago in the early 1960s, prior to major changes in lake use and conservation management.
