About this map

The Sierra Pelona range dominates this mid-1930s survey, revealing a landscape defined by critical infrastructure and steep terrain within the Angeles National Forest. Industrial development is centered on the San Francisquito Power House No 1 and its associated Surge Tank, linked to the city by the prominent Los Angeles Transmission Line. These features mark the region's role in the California water and power system following the catastrophic flood event in the canyon nearly a decade prior to this edition.

Two major drainages, San Francisquito Canyon and Bouquet Canyon, carve through the mountains, the latter fed by the Bouquet Reservoir. The map tracks several fire-management features like the Firebreak and Control Line, essential for protecting the watershed. Small settlements like Camp 2 and family-named landmarks such as Haskell Canyon and Bee Canyon provide touchpoints for local historians and genealogists tracking the development of these rugged corridors.
