1966 Map of Humphreys Peak

About this map

San Francisco Mountain dominates this mid-1960s survey, rising sharply from the high desert plateau to the volcanic heights of Humphreys Peak and Agassiz Peak. The map reveals the dual nature of this landscape as both a site for mountain recreation and rigorous scientific study. The established Arizona Snow Bowl with its Ski Lift occupies the western slopes, while the southern reaches are dedicated to the Fort Valley Experimental Forest, including the Fort Valley Experimental Forest Station. Numerous mountain springs such as Big Leroux Spring and Philomena Spring are documented across the Coconino National Forest, essential water sources in the arid environment. Man-made infrastructure like the Pipeline and scattered resource extraction sites, including Cinder Pits and a Gravel Pit, reflect the mid-century industrial demands on the surrounding wilderness.
