About this map

The copper-rich spine of the Keweenaw Peninsula is captured here in the mid-1940s, shortly after the height of its primary mining era. The rugged landscape is defined by massive ridges including Brockway Mountain and Mt Lookout, with the Eagle Harbor Grant stretching across the northern interior. Small settlements like Delaware and Mandan sit along the central valley, locations long associated with the copper mining industry that once drove the regional economy.

Coastal geography dominates the northern edge, where Lake Superior meets the finger-like inlets of Agate Harbor and North Bay. To the south, the terrain drops toward the shores of Lac La Belle and the winding course of the Montreal River. This survey preserves the specialized local infrastructure of the time, from the high-altitude Brockway Mountain Drive to the network of lakes and ponds like Meadow Lake and Lake Glazon that dot the high ridges and low harbors of the peninsula.
