2011 Map of Outer Island

About this map

Outer Island stands as a lonely sentinel in the waters of Lake Superior, representing the northernmost reach of this Wisconsin archipelago. This 2011 survey illustrates the island's isolation, dominated by a dense interior and rugged shoreline. Near the northern tip, the Outer Island Light marks a vital point of navigation for maritime traffic navigating the expansive lake. The surrounding waters are defined by the Outer Island Shoal, a hazardous underwater feature that historically necessitated the presence of the lighthouse. Unlike more developed coastal areas, the map reveals a landscape primarily shaped by natural contours and limited human infrastructure, centered almost entirely around its navigational aids.
