1966 Map of Azusa

About this map

Angeles National Forest dominates the northern half of this map, where the peaks of Monrovia Peak and Rankin Peak overlook deep-cut drainages like Fish Canyon and Sawpit Canyon. The landscape transition is sharp, shifting from these steep wilderness canyons to the rapidly expanding suburban centers of Azusa, Duarte, and Glendora along the Foothill Blvd corridor. The 1970s revisions, noted in purple, highlight significant urban infill and residential growth near major institutions such as Citrus College and the City of Hope National Medical Center.
