1948 Map of Manitou Island

USGS Topo · Published 1974

About this map

Manitou Island and the easternmost tip of the Keweenaw Peninsula define this maritime landscape at the mid-century. The survey, field-checked shortly after the war, documents the critical navigation aids serving the heavy shipping traffic of Lake Superior. Primary landmarks include the Gull Rock Lighthouse and the Manitou Island LH, which sat at a strategic turn for vessels heading toward the Soo Locks or Duluth.
