About this map

Camp Joseph H Pendleton dominates this coastal landscape, covering the vast Santa Margarita Y Las Flores Naval Reservation during the late 1940s. The topography is defined by the sharp ascent of San Onofre Mountain and the deep incisions of Las Pulgas Canyon and Lumbre Canyon, which drain toward the Gulf of Santa Catalina Pacific Ocean. Along the shore, the Atchison Topeka and Santa Fe railroad provides the primary transportation artery, connecting small sidings and outposts like Agra and Don.

Cultural history is anchored by the Las Flores Mission (Ruins) near the mouth of Las Flores Creek, a remnant of the region's earlier ranching and mission era. The map details the mid-century military infrastructure of Camp Pulgas and various firing positions, including a Target Range and Rifle Range. In the south, the Santa Margarita River winds through the coastal plain near the settlement of Stuart, illustrating the intersection of natural river drainage and naval defense installations.
