About this map

K I Sawyer Air Force Base dominates the central plateau of this Marquette County landscape, serving as a massive Cold War-era footprint amidst the dense woodlands of the Escanaba River State Forest. The map documents the heavy industrial heritage of the Upper Peninsula, particularly around the iron mining hubs of Ishpeming, Negaunee, and Palmer. Extensive mining infrastructure is evident through features like the Humboldt Mine (Tailings Pond), the National Mine, and the Greenwood Mine, alongside several smaller operations such as the Mackinaw Mine.

Transport corridors like the Chicago and North Western and Escanaba and Lake Superior railroads connect these industrial sites to the shoreline of Lake Superior at Harvey. The map also captures several company towns and small settlements, including Gwinn, New Swanzy, and Princeton, which developed to support the region's extraction and timber economies. The northern reaches show a transition toward forestry and research at the Upper Peninsula Experimental Station (USFS).
