1966 Map of Azusa

About this map

Angelles National Forest dominates the northern landscape of this San Gabriel Valley survey, where the steep canyons of Monrovia Canyon and Fish Canyon descend toward a corridor of mid-century suburban expansion. The era's infrastructure is clearly defined by the Santa Fe Flood Control Basin and the spreading grounds along the San Gabriel River, essential for managing water in this alluvial landscape. The valley floor is densely packed with local institutions, from the City of Hope National Medical Center in Duarte to the expanding campuses of Citrus College and Azusa Pacific College. The industrial and recreational character of the late 1960s is evident in the numerous Gravel Pits in Irwindale and the presence of the Irwindale Raceway. This map captures the transition where the wild peaks of Monrovia Peak meet the organized grids of Azusa and Glendora during a peak period of Southern California development.
