The copper-rich Keweenaw Peninsula is captured here in the mid-1940s, with updates from the 1970s reflecting the industrial and social landscape of northern Michigan. Mining operations are central to the region's geography, anchored by the Ahmeek Mine and the Red Jacket Mine. A dense network of company towns and settlements like Bumbletown, Phillipsville, and Centennial Heights cluster around the mineral veins, connected by transportation routes such as the Old Railroad Grade.
