1940 Map of Manitou Island

USGS Topo · Published 1940

About this map

Manitou Island sits off the tip of the Grant peninsula, guarding the waters of Lake Superior in this preliminary 1940 survey. This remote maritime landscape is defined by its navigation aids, specifically the Manitou Island L H on the island's eastern edge and the Gull Rock L H on the tiny outcrop of Gull Rock to the west. The mainland portion of the map covers the dramatic eastern terminus of the Keweenaw Peninsula, including the prominent Keweenaw Point. Inland from the shoreline, Schlatter Lake and the wetlands of Union Creek dominate the interior of the Grant township section. The map's coastal detail includes named inlets such as Keystone Bay and High Rock Bay, showing the jagged interface between the rocky Michigan shoreline and the lake during the early 20th century.
