1966 Map of Humphreys Peak

About this map

The San Francisco Mountains dominate this 1966 topographic study, anchored by the highest point in Arizona, Humphreys Peak. The landscape reflects a specialized mix of recreation and research, featuring the Arizona Snow Bowl ski area and the Fort Valley Experimental Forest Station. The volcanic character of the terrain is evident in the Cinder Pits near Hochderffer Hills and the massive Inner Basin carved into the mountain's core. Water sources are critical in this high-elevation environment, documented through a network of isolated points like Big Leroux Spring, Bismarck Lake, and Philomena Spring. Historic land use is further marked by the Weatherford Trail and the presence of the Michelbach Ranch on the western edge of Hart Prairie.
