1966 Map of Azusa

About this map

The Angeles National Forest dominates the northern half of this mid-1960s study, where the San Gabriel River carves through steep terrain beneath Monrovia Peak and Mt Bliss. This section of the San Gabriel Mountains is heavily engineered for water management, featuring the Cogswell Reservoir and Morris Reservoir to regulate the flow before it reaches the valley floor. In the southern foothills, the transition from forest to urban settlement is sharp, defined by the expanding borders of Monrovia, Duarte, and Azusa. These communities are threaded together by the Atchison Topeka And Santa Fe and Southern Pacific railroads, which parallel major thoroughfares like Foothill Blvd. Notable regional institutions such as the City of Hope National Medical Center, Citrus Jr College, and Azusa Pacific College highlight the area's mid-century development as a hub for education and healthcare in Los Angeles County.
