1932 Map of Russell Valley

About this map

The Santa Monica Mountains dominate the southern portion of this 1932 topographic sheet, where sharp elevation gains define the approach to the Las Virgenes area. This survey, conducted just before major residential expansion, captures the early automotive route of the Ventura Highway as it cuts across the northern landscape near Russell Valley. The topography is marked by a network of steep drainages, including Triunfo Canyon and Lobo Canyon, which underscore the geographic isolation of these coastal ranges during the early twentieth century.
