1948 Map of Las Pulgas Canyon

About this map

Camp Joseph H Pendleton Naval Reservation dominates this coastal landscape, showing a transition between early California heritage and mid-century military infrastructure. The presence of the Las Flores Mission Ruins near the mouth of Las Flores Creek points to the area's deep history, while the surrounding terrain is marked by a complex of canyons like Las Pulgas Canyon and Piedra de Lumbre Canyon. These natural corridors dictate the flow of modern transport, with the Atchison Topeka and Santa Fe Coast Lines and U S Highway 101 hugging the narrow coastline beneath the height of San Onofre Mountain. Military use is evident in the development of Camp Pulgas and various facilities like the Target Range and Rifle Range. Coastal settlements such as Agra, Don, and Las Flores are small but critical markers along the Pacific front.
