1942 Map of Chileno Canyon

About this map

The San Gabriel Mountains dominate this 1930s survey, showing a landscape defined by water management and recreational use during the early development of the Angeles National Forest. The presence of Dam No 2 and the West Reservoir along the San Gabriel River illustrates the region's focus on Flood Control for the growing coastal plains. Human presence in this high-elevation terrain is marked by small outposts such as Spring Camp, Tool Cabin, and Stone Cabin, alongside the Pasadena Bait Club situated near the river fork. The newly constructed Angeles Crest Highway snakes through the northwest corner, providing access to peaks like Monrovia Peak and lookouts including the Pine Mtn Lookout. The map also records numerous firebreaks and trails, reflecting a landscape heavily managed for fire prevention and forestry.
