1941 Map of Devore

About this map

Atchison Topeka and Santa Fe and Union Pacific rails dominate the landscape where the San Gabriel Mountains and San Bernardino Mountains meet. This survey, completed in the late 1930s, reveals a complex water management and industrial infrastructure designed to harness the drainage of Lytle Creek. The presence of the Lytle Creek Water Spreading Area, multiple numbered weirs, and the Fontana Power Plant indicates the critical role of water conservation and power generation for the developing valley below. Near the settlement of Devore, local landmarks such as the Cajon Sch and the Glenn Helen Infirmary appear alongside transportation corridors like Cajon Blvd and Kendall Drive. The map also captures early aviation history with the Fontana Airport and its associated Beacon, positioned just north of the grid-patterned agricultural and residential expansion along Highland Avenue.
