Lake Superior dominates this mid-century topographic study, which captures the immediate shoreline interface of Michigan's Copper Country. The terrain transitions from the deep waters of the lake to the elevated plateau of the Keweenaw Peninsula, marked by the boundary between Keweenaw Co and Houghton Co. Infrastructure along this northern coast is centered on municipal utility sites, including the Tamarack Waterworks and Calumet Waterworks, which were vital for the industrial and residential needs of the nearby mining districts.
