1948 Map of Delaware

USGS Topo · Published 1970

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.
