1942 Map of Chileno Canyon

About this map

The West Fork San Gabriel River carves a deep path through these central reaches of the San Gabriel Mountains during the mid-1940s. This territory is dominated by the Angeles National Forest, where the landscape is defined by steep drainages and fire management infrastructure. A Flood Control Reservoir sits behind Dam No. 2, illustrating early water management efforts in the canyon. The Angeles Crest Highway snakes along the northwestern corner, providing high-altitude access to a wilderness dotted with isolated outposts like the Pasadena Bait Club and Spring Camp. Topographic details reveal an extensive network of firebreaks and trails, including a prominent firebreak leading toward the Pine Mtn Lookout and Monrovia Peak, which served as vital observation points for forest protection in this era.
