1945 Map of Lebec

USGS Topo · Published 1945

About this map

The San Andreas Rift Valley cuts a prominent northwest-to-southeast path across this mid-1940s survey of the mountain passes between the Central Valley and Southern California. This corridor serves as the primary artery for transportation, carrying the winding route of highway 99 through Castaic Valley and past the settlement of Lebec. The map captures the infrastructure of the era, including the California Southern Edison Transmission Line and the LA-SF Airway Beacon, critical for early aviation navigation along this treacherous mountain route.
