2015 Map of Rocky Island

About this map

Apostle Islands National Lakeshore encompasses several distinct landmasses within the cold waters of Lake Superior, providing a specialized look at the northernmost reaches of Wisconsin. The isolation of Devils Island at the northern edge of the archipelago is contrasted by the proximity of Rocky Island and South Twin Island to the southeast. These islands are part of a protected maritime landscape that preserves the natural state of the archipelago, where underwater features like Devils Island Shoal pose challenges to navigation. Further south, the map details the shorelines of Bear Island, Otter Island, and Ironwood Island, illustrating the distribution of these landforms across the coastal waters of Ashland County. The survey provides a clear view of the federal boundaries and the varied topography of each island within the national lakeshore.
