About this map

Angeles National Forest provides the backdrop for this mid-1930s survey of the northern Los Angeles backcountry. The map documents a critical period of infrastructure development for the region, centered on the Los Angeles Aqueduct and the San Francisquito Power House No 2. These engineering works follow the path of San Francisquito Canyon, illustrating the era's reliance on canyon corridors for both water and power transmission into the growing Los Angeles basin.

Aside from industrial markers like the Transmission Line, the map captures a landscape of steep canyons and firebreaks. Local life and recreation are represented by the Public Camp along the Elizabeth Lake Canyon Road and the Bee Sch near Drinkwater Flat. The detailed topographic work by C.W.H. Nessler reveals a network of firebreaks and trails across Red Mountain, highlighting the management of this fire-prone wilderness during the early 20th century.
