About this map

The East Branch Escanaba River and the Middle Branch Escanaba River converge near the company-planned town of Gwinn, a central hub in Marquette County's history. This 2019 survey illustrates the dense cluster of settlements that grew around the region's iron mining heritage, including Austin, Princeton, and New Swanzy. The transition from industrial roots to modern aviation is evident in the northern portion of the map, where the sprawling Sawyer International Airport occupies the former military site at K I Sawyer, complete with its distinct residential grid and Bomber Alert Rd.

Away from the developed centers, the landscape is defined by the Plains and a high concentration of small glacial lakes such as Little Shag Lake, Johnson Lake, and Mehl Lake. Small family-named landmarks and local infrastructure, including the Gwinn Cem and the Lesterson-Dempsey Airstrip, provide specific points of interest for genealogists and local historians tracing the evolution of this Upper Peninsula community.
