1937 Map of San Francisquito

About this map

San Francisquito Power House No 1 and its accompanying Surge Tank anchor the industrial infrastructure of this mountainous region during the 1930s. This survey, conducted just years after the devastating 1928 dam collapse in the same canyon, captures a landscape defined by water management and power generation for the growing Southern California metropolis. The Los Angeles Transmission Line cuts across the Sierra Pelona range, marking the vital energy corridor through the Angeles National Forest. In the northeast, the Bouquet Reservoir appears as a significant water storage feature, while the presence of Camp 2 along the Bouquet Canyon road suggests localized activity related to forest management or utility maintenance. Numerous steep drainages, such as Clearwater Canyon and Texas Canyon, carve the terrain between Jupiter Mountain and the surrounding peaks.
