About this map

Delaware and Mandan sit as focal points for human activity along the copper-bearing ridges of the northern Keweenaw Peninsula, caught here in a 1948 survey based on mid-war aerial photography. The landscape is dominated by the dramatic east-west orientation of the Brockway Mountain ridge, which creates a natural barrier between the protected waters of Agate Harbor on Lake Superior and the interior valleys. The mapping reveals a complex network of seasonal drainages and small lakes, including Lake Bailey and Lac La Belle, which supported the early industrial and maritime development of the region.

Evidence of the Copper Country's infrastructure is visible in the winding path of Lake Shore Drive and the positioning of settlements along the Montreal River. High points like Mt Lookout and Mt Bohemia offer topographic context for the mining and timber interests that shaped this remote stretch of Michigan. The detail captured along Bailey Creek and the Eagle Harbor River provides researchers with a precise look at the drainage patterns and land use before later twentieth-century modifications.
