1948 Map of Manitou Island

About this map

Manitou Island and the rugged tip of the Keweenaw Peninsula define this coastal survey, capturing a remote landscape of the Upper Peninsula as it was field-checked in the late 1940s. The map highlights the critical maritime infrastructure of Lake Superior, specifically the Manitou Island LH (Radio Beacon) on the island's eastern end and the Lighthouse situated at Gull Rock. These navigational aids served as sentinels for vessels rounding Keweenaw Point. Inland, the terrain is marked by a series of isolated water bodies, including Schlatter Lake, Gill Lake, and Perch Lake. A prominent Telephone Line is shown stretching across the peninsula and onto the island, tracing a rare path of human utility through the dense forests and rocky shoreline. The map provides a clear record of the natural coastline, from High Rock Bay to the sheltered waters of Fishermans Bay.
