About this map

The Copper Country of Michigan's Keweenaw Peninsula is captured here in the late 1940s, highlighting the industrial legacy and maritime infrastructure of the region. Eagle Harbor serves as the primary coastal hub, featuring a Coast Guard Sta and the grid of a settlement deeply tied to Lake Superior. Moving inland, the landscape reveals the heavy footprint of mining history at Copper Falls and the settlement of Central, where the Old Railroad Grade and Central Lake indicate a legacy of resource extraction and transport.

Elevation changes are prominent along Brockway Mountain Drive, which skirts the ridges overlooking Great Sand Bay and The Marshes. The interior is dotted with remote outposts like Nepco Camp No 7 and numerous water bodies, including Eliza Lake and Copper Falls Lake. Local genealogy is anchored by landmarks like Pine Grove Cem, providing a precise look at the community's footprint during this era of northern Michigan history.
