About this map

The San Gabriel River cuts through the steep terrain of the Angeles National Forest before spilling into the industrializing San Gabriel Valley. During the mid-1960s, the foothills from Monrovia to Glendora transitioned from agricultural fringes to dense suburban corridors. The map highlights the critical role of water management in this landscape, showing the massive Santa Fe Flood Control Basin and the Santa Fe Dam Spillway protecting the valley below.

Institutional growth is evident at the City of Hope National Medical Center in Duarte and the campus of Azusa Pacific College. Transportation networks are dominated by the Atchison Topeka and Santa Fe and Southern Pacific railroads, alongside historic Foothill Blvd. The northern mountain reaches remain largely undeveloped, punctuated only by peaks like Monrovia Peak and the high-elevation Cogswell Reservoir.
