About this map

Copper mining infrastructure dominates this post-war survey of the Keweenaw Peninsula, centered on the industrial corridor between Houghton and Chassell. The landscape is a detailed record of extractive history, showing the expansive operations of the Isle Royale Mine and the Old Superior Mine alongside smaller settlements like Dodgeville and Hurontown. Along the waterfront, the Michigan College of Mining and Technology stands as a focal point of the region's academic and technical identity.

Transport networks are clearly defined by the Duluth South Shore and Atlantic railroad, which traces the coastline of Portage Lake through Pilgrim and Sunshine Beach. In the southern reaches, the map transitions to the wetlands surrounding the Sturgeon River and Pike Bay, illustrating the shift from the industrial Copper Range to the natural drainage systems of the Little Otter River and North Branch Otter River.
