1966 Map of Cucamonga Peak

USGS Topo · Published 1980

About this map

Cucamonga Peak dominates the northern skyline of this San Bernardino landscape, where the steep canyons of the Angeles National Forest meet the expanding citrus groves and suburban tracts of the valley floor. The map documents a significant era of post-war growth, with purple-tinted urban extensions spreading through Alta Loma and Etiwanda up to the base of the mountains. This transition is marked by infrastructure like the Flood Control Basin and the Day Canyon Station, designed to manage the seasonal runoff from Cucamonga Canyon and Deer Canyon.
