About this map

Mohawk and the adjacent settlement of Fulton stand at the heart of this Keweenaw Peninsula survey, revealing the legacy of copper mining in Northern Michigan. Originally mapped in 1946 with revisions through 1975, the map documents a landscape defined by industrial extraction and the natural barrier of the Cliff Range. The presence of the Gratiot Mine and named locations like Seneca and Ojibway point to the area's history as a mining hub, while the Old Railroad Grade indicates the former transportation networks that once connected these remote camps.

Water plays a critical role in the geography here, with the Gratiot River flowing west and the Trap Rock River and Tobacco River draining toward the southeast. Numerous small bodies of water like Thayer Lake, Seneca Lake, and Deerwater Lake dot the wetlands and wooded tracts between the ridges. The boundary between Keweenaw County and Houghton County crosses the southern portion of the sheet, marking a significant local jurisdictional line for genealogists and regional historians.
