1972 Map of Boise South

About this map

Boise and Garden City are shown during a period of significant mid-century expansion, centered on the corridor of the Boise River. The landscape reveals a complex network of irrigation infrastructure including the Ridenbaugh Canal, New York Canal, and Warm Springs Canal, which supported the valley's development alongside the Union Pacific railroad. The map identifies key civic landmarks like the State Capitol, the Boise State College campus, and the State Penitentiary near the base of the foothills.
