1928 Map of Azusa

About this map

Monrovia and Azusa anchor this 1920s landscape at the foot of the Angeles National Forest. The map illustrates a transitional period of agricultural and early suburban expansion, where the San Gabriel River and its various washes like Sawpit Wash and Dalton Wash dictate the layout of the land. Industrial activity is evident near the river through multiple Gravel Pit sites, while the presence of the Jewish Sanitarium and Liveoak Cemetery provides valuable data for local history and genealogical research. The region's dependence on rail is clear, with the Atchison Topeka and Santa Fe and Southern Pacific lines cutting across the valley, connecting settlements like Duarte and Irwindale to the broader San Gabriel Valley economy.
