About this map

K I Sawyer Air Force Base stands as a central landmark in this 1980s landscape of the central Upper Peninsula, surrounded by the expansive Escanaba River State Forest. The map documents a region defined by its industrial heritage and military presence, where the iron mining towns of Ishpeming, Negaunee, and Republic remain prominent. Several specific mining operations are identified, including the Greenwood Mine, National Mine, and New Richmond Mine, reflecting the area's deep connection to the Marquette Iron Range.

Transport and research networks crisscross the terrain, from the Soo Line and Chicago and North Western railroads to the Upper Peninsula Experimental Station (USFS) near Dukes. Settlement patterns follow the river systems, notably the many branches of the Escanaba River, which link smaller communities like Gwinn, Little Lake, and Northland. This survey provides a clear view of the rural infrastructure and timberlands before the eventual decommissioning of the air base.
