1953 Map of Cucamonga Peak

About this map

Cucamonga Grant and its agricultural transition define the southern foothills of the San Gabriel Mountains in this early 1950s survey. The landscape is sharply divided between the high wilderness of the Angeles National Forest and the budding citrus and vineyard developments of Alta Loma and Etiwanda. Transport networks are central to the region's character, with the Atchison Topeka and Santa Fe and the Pacific Electric lines running parallel through the alluvial plains. To the north, the terrain rises abruptly toward Cucamonga Peak and Ontario Pk, where a network of trails such as the Telegraph Trail and Shortcut Trail connect remote landmarks like Kelly Camp and the Joe Elliot Tree Memorial. The map also captures the critical water infrastructure of the era, from the Day Canyon Guard Sta to the washes of Deer Creek and Day Creek that supported the growing settlements below.
