USGS Topo · Published 1927About this map
The citrus-growing landscapes of Covina and Charter Oak are showcased in this mid-1920s survey, illustrating the transformation of the eastern San Gabriel Valley. The map captures a transition from large rancho-era tracts like Rincon De La Brea and the Diamond Bar Ranch to organized suburban blocks and industrial corridors. Transport infrastructure is particularly dense, with the Pacific Electric and Southern Pacific railroads cutting through the basin to serve the agricultural economy.
