1949 Map of Delaware

USGS Topo · Published 1949

About this map

Lake Superior dominates the northern edge of this Keweenaw Peninsula terrain, where the coastline is defined by protected waters like Agate Harbor and Grand Marais Harbor. The interior landscape reveals the dramatic geological ridges of the Copper Country, with Gratiot Mountain and Mt Lookout rising above a dense network of inland waters. The Montreal River cuts through the central valley, passing the small settlements of Delaware and Mandan. These communities, established during the region's copper mining boom, appear here in the late 1940s alongside the iconic Brockway Mountain Drive. The map captures a transition toward recreation and conservation, evidenced by Esrey Park along the Shore Drive, while still documenting the remote pockets of water like Bailey Lake and Lac La Belle that shaped early Keweenaw industry and travel.
