2022 Map of Rocky Island

About this map

Apostle Islands National Lakeshore protects a distinct archipelago in Lake Superior, where isolation and geology define the landscape. This 2022 survey documents the varied islands of the northern chain, from the northernmost reaches of Devils Island and its nearby Devils Island Shoal to the larger landmasses of Rocky Island and South Twin Island. The map records essential trail infrastructure used for navigating these remote island interiors, specifically the Rocky Island Steps Trl and the South Twin Island Trl. Surrounding islands such as Bear Island, Otter Island, and Ironwood Island are also shown, illustrating the spatial relationship between these glaciated landforms. The presence of these named islands and their internal paths provides a clear record of the modern shoreline and recreational access within this protected maritime region of Ashland County.
