2018 Map of Outer Island

About this map

Apostle Islands National Lakeshore encompasses the entirety of this isolated landmass in Lake Superior. This survey captures the topographical character of Outer Island, the northernmost of the Apostle Islands chain. The island's eastern shoreline is defined by the curve of Austad Bay, while the waters to the north are marked by the Outer Island Shoal. The interior terrain is relatively uniform, with elevations subtly rising above the lake level, mapped with 10-foot contour intervals. This modern record reflects the island's status as a protected natural area, showing no significant roads or permanent settlements, preserving the character of this remote Lake Superior outpost.
