About this map

Lake Superior shorelines define this 1948 survey of Keweenaw County, where the rugged maritime and mining history of the Upper Peninsula is etched into the landscape. The village of Eagle Harbor serves as the primary coastal anchor, featuring a prominent Coast Guard Sta and LH beacon guarding the rocky inlet. Inland, the map reveals the era's transition from active industrial extraction to a burgeoning scenic destination, notably along the winding Brockway Mountain Drive and the ridges overlooking Great Sand Bay.

Resource extraction footprints are visible at the settlements of Copper Falls and Central, where an Old Railroad Grade and numerous Old Road segments trace former transport corridors through dense wetlands like The Marshes and Cedar Swamp. Water is everywhere in this geography, from the interior depths of Eliza Lake and Owl Lake to the various drainages of Eagle River and Montreal River that cut through the topography at Madison Gap.
