2013 Map of Outer Island
USGS Topo · Published 2013About this map
Outer Island stands as a prominent landmass within the waters of Lake Superior, marked by a network of paths and small streams that reach across its interior. On the northeastern edge, the shoreline curves to form Austad Bay, a sheltered indentation in the otherwise exposed coast. To the north, the presence of the Outer Island Shoal indicates the underwater extensions of the island's geography, presenting a hazard for navigation in this stretch of the Great Lakes. This 2013 survey by the U.S. Geological Survey documents the island's modern topographic state, focusing on the natural contours and drainage patterns that define this isolated landform within Ashland County.
