About this map

The San Gabriel Mountains dominate this 1942 survey, revealing a landscape defined by critical water management and high-altitude recreation during the early 1940s. The West Fork San Gabriel River flows through the center of the sheet, feeding into a prominent Flood Control Reservoir. This infrastructure represents the massive engineering efforts undertaken to manage the watershed above the Los Angeles basin. In the canyons, the Pasadena Bait Club suggests the area's popularity for local sport, while the Angeles Crest Highway snakes through the northern peaks.
