1927 Map of Glendora

About this map

Glendora sits at the foot of the Angeles National Forest, where steep canyons like Big Dalton Canyon and Englewild Canyon give way to an organized grid of citrus groves and residential expansion. The landscape in the late 1920s is defined by its transition from the rugged South Hills and Walnut Hill to the agricultural flats. This area serves as a critical junction for three major rail lines: the Pacific Electric, the Southern Pacific, and the Atchison Topeka and Santa Fe, reflecting its importance in the regional transit and citrus economy.
