1903 Map of Cucamonga

USGS Topo · Published 1927

About this map

San Antonio Mountains dominate the northern landscape of this survey, where deep drainages like Cucamonga Canyon and San Antonio Canyon spill out into the alluvial plains of the Chino Valley. This late nineteenth-century topography, recorded by W.S. Post, reveals the early agricultural and transit foundations of the Inland Empire before the massive post-war expansion. The grid of the San Bernardino Base Line organizes a series of emerging citrus and vineyard towns, including Ioamosa, Rochester, and Etiwanda.
