About this map

Mining operations dominate the landscape of the Marquette Iron Range in this mid-century survey, centered on the company town of Gwinn. The concentrated industrial activity is evident in the cluster of shafts including Princeton No 1 Mine, the Stegmiller Mine, and the Stephenson Mine near the settlements of Princeton and Austin. These iron ore workings are linked by the Chicago and North Western railway, which follows the corridor of the East Branch Escanaba River.

To the northeast, the expansion of the K I Sawyer Air Force Base introduces a significant military presence, contrasting with the numerous natural kettle lakes like Johnson Lake and Shag Lake that dot the glacial terrain. The map also captures infrastructure such as the Old Railroad Grade and the Gwinn Lookout Tower, reflecting a period where heavy industry and strategic defense infrastructure intersected in Michigan's Upper Peninsula.
