About this map

The San Gabriel Mountains dominate the northern landscape of this 1930s survey, rising sharply above the nascent citrus-growing communities of the San Gabriel Valley. The recently completed Morris Dam and its sprawling Morris Reservoir stand as a massive engineering feat for the era, while the Metropolitan Aqueduct cuts through the foothills to the south. Educational institutions are surprisingly prominent for a rural region, including the Carlin Military Academy, Girls Collegiate Sch, and Citrus Union High School.
