1926 Map of El Monte

About this map

El Monte serves as the focal point for this mid-1920s landscape, positioned at a vital junction where the Southern Pacific and Pacific Electric lines converge. The surrounding territory is defined by the historic rancho partitions, including Potrero Grande and San Francisquito, which organize the grid of early suburban developments like Rosemead and Wilmar. Industry and infrastructure are prominent, from the Edison Power Line cutting across the valley to the O'Donnel Oil Refinery near the southern boundary. The natural hydrology of the Rio Hondo and San Gabriel River dictates the layout of the roads, such as Durfee Road and Whittier Boulevard. Scattered throughout these rural blocks are essential community landmarks, including the Temple School and Roosevelt School, marking the locations of early 20th-century neighborhoods before the post-war building boom transformed the San Gabriel Valley.
