1948 Map of Manitou Island

About this map

Manitou Island and the rugged eastern tip of the Keweenaw Peninsula stand as maritime sentinels in the waters of Lake Superior. This survey, updated with 1975 aerial revisions, documents the navigational infrastructure essential for Lake Superior shipping, notably the Gull Rock Lighthouse and the Manitou Island LH (Radio Beacon). The land is largely undeveloped, defined by significant water bodies such as Schlatter Lake and Gill Lake on the mainland, and Perch Lake on the island itself. The coastline is marked by deep indentations like Fishermans Bay and High Rock Bay, providing natural shelter. A solitary Telephone Line represents the only significant man-made utility traversing the interior, connecting the lighthouse facilities to the mainland near Keweenaw Point, highlighting the isolation of this Lake Superior outpost.
