1938 Map of Beartrap Canyon

About this map

The mountain pass corridors of northern Los Angeles County are captured here during the 1930s, showing the early infrastructure that connected the Central Valley to the coast. Route 99 winds through the canyons, serving as a primary artery alongside a major Transmission Line and the Liebre Pumping Sta. Small roadside outposts like the Halfway Inn and landings such as French Flat and Osito provide evidence of early automobile-era travel and local habitation in this demanding landscape.
