1948 Map of San Onofre Bluff

About this map

Camp Pendleton Naval Reservation dominates the coastal terrace of northern San Diego County in this mid-century portrait of the California shoreline. The landscape is defined by the sharp transition from the Gulf of Santa Catalina to the rising terrain of San Onofre Bluff. This stretch of coast serves as a critical transportation corridor, where the Atchison Topeka and Santa Fe railroad runs parallel to the Santa Fe Highway and the historic Route 101. The map captures the infrastructure of the era, showing the highway transitioning between four and six lanes near the small settlement of Agra. The topography reveals the deeply incised drainages typical of this marine terrace, illustrating the coastal geography before the extensive modern developments that would later characterize the region between San Clemente and Oceanside.
