The iron mining heritage of Marquette County is etched across this 1952 landscape, centered on the company towns and subterranean works near Gwinn. Dense clusters of mining operations including the Princeton No 1 Mine, Stephenson Mine, and Jopling Mine define the southern portion of the sheet, where the Chicago and North Western rail lines connect these industrial hubs to the wider region. The terrain transitions from the Ragged Hills down toward the southern shore of Lake Superior at Harvey.
