About this map

The copper-rich spine of the Keweenaw Peninsula is the focal point of this 1948 survey, where industrial mining and heavy timberland intersect. The settlement of Mohawk serves as a primary hub, situated near the Gratiot Mine and the rail-connected community of Fulton. This landscape is defined by the prominent ridge lines of the Cliff Range and Copper Range, which directed the paths of the Copper Range railroad and established the geological boundaries for the region's mineral extraction.

A dense network of watercourses, including the Traprock River and Gratiot River, drains the interior marshlands and ponds like Thayer Lake and Seneca Lake. The map clearly delineates the civil boundaries of townships such as Allouez and Sherman, alongside smaller mining-era sites like Seneca and Ojibway. For the researcher, the proximity of the rail lines to these specific mine sites provides a clear record of the infrastructure that powered Michigan's copper industry during the mid-20th century.
