1903 Map of Cucamonga

About this map

The San Antonio Mountains and the San Gabriel Timber Land Reserve dominate the northern landscape, where steep canyons like Cucamonga Canyon and San Antonio Canyon descend into the fertile alluvial plains below. This turn-of-the-century survey illustrates a burgeoning agricultural and transit corridor defined by the San Bernardino Base Line. The settlement pattern reflects the early development of the Inland Empire, with townsites like Cucamonga, Ontario, and Etiwanda established along a dense grid of roads and competing rail lines.
