1948 Map of Delaware

About this map

The rocky Keweenaw Peninsula shoreline meets Lake Superior in this mid-century survey, showcasing a landscape defined by its copper mining heritage and dramatic topography. The inland settlements of Delaware and Mandan sit along the winding course of the Montreal River, positioned south of the steep ridges that separate the interior from the coast. The northern edge of the map is punctuated by deep-water features like Agate Harbor and Grand Marais Harbor, which are connected by the iconic Brookway Mountain Drive and Lake Shore Drive.
