About this map

Delaware and Mandan sit as the primary interior settlements in this survey of Michigan's northern Keweenaw Peninsula, reflecting a landscape defined by the copper mining history and rugged lakefront geography of the mid-twentieth century. The terrain is dominated by prominent elevations like Brockway Mountain and Mt Lookout, with the iconic Brockway Mountain Drive following the ridgeline above the Lake Superior shoreline. Water is central to the area's layout, from the sheltered Agate Harbor and Grand Marais Harbor on the northern coast to the inland expanse of Lac La Belle in the south.

The complex drainage of the peninsula is visible through the winding paths of the Montreal River and Gratiot River, which cut through the high ground of Gratiot Mountain. This map documents a transitional period when established mining locations like Delaware remained distinct landmarks before the further expansion of recreational tourism. Notable peaks such as Mt Bohemia, featuring its lookout tower, provide clear navigational points for researchers tracing the historical development of Keweenaw County.
