About this map

Apostle Islands dot the waters of Lake Superior in this mid-century survey of the La Pointe Twp region. The map focuses on the northernmost reaches of the archipelago, where the landscape is defined by secluded islands rather than mainland settlements. Notable navigational markers include a radio tower and light on Devils Island, which stands as the northern sentinel above the Devils Island Shoal.

Topographic detail reveals the varied elevations of Bear Island, Rocky Island, and Cat Island, while the smaller landmasses of Ironwood Island, North Twin Island, and South Twin Island appear further east. This map provides a clear record of the archipelago's configuration before significant modern changes, documenting the relationship between these landforms and the surrounding lake depths as they were surveyed in the early 1960s.
