About this map

Dollar Bay and the surrounding industrial landscape of Michigan's Keweenaw Peninsula are captured in this late 1970s orthophotoquad. The imagery provides a raw look at the shoreline along Portage Lake, where the small settlements of Senter and Point Mills sit amidst a patchwork of forested sections and cleared land. This specific format, a collaboration between the U.S. Geological Survey and the Soil Conservation Service, emphasizes the actual ground cover and land use patterns of the era rather than just traditional topographic contours.

To the south, the intricate wetlands where the Sturgeon River and Portage River meet create a complex waterway network leading toward the eastern reach of Lake Superior. The orthophoto allows researchers to identify specific clearings, industrial sites, and property boundaries as they existed during the autumn of 1978, offering more texture than a standard line map for those tracing the development of these Upper Peninsula communities.
