2014 Map of Gwinn

About this map

Gwinn and the surrounding mining-era settlements of Princeton, Austin, and New Swanzy occupy the central valley of the Escanaba River system in Marquette County. This 2014 survey captures the significant aviation presence at the northern edge of the quadrangle, where Sawyer International Airport and the residential community of K I Sawyer occupy the former air force base grounds. The landscape is defined by the convergence of the Middle Branch Escanaba River and the East Branch Escanaba River, creating a complex network of wetlands and small lakes like Shag Lake and Johnson Lake. The map details the transition from the concentrated residential streets of Gwinn to the open tracts of the Plains and the scattered clearings at Swanzy. Genealogists will find the location of the Gwinn Cem and various local access routes like Kelly Johnson Memorial Dr useful for placing family sites within this historic iron-mining district.
