1943 Map of San Clemente Island South

About this map

The Naval Ocean Systems Center San Clemente Island Facility dominates the rugged southern tip of the island, a terrain defined by its strategic military role and isolated coastline. This 1943 survey, updated via 1977 aerial photography, reveals the high ridges and steep canyons that descend toward the Pacific Ocean. The coastline is punctuated by notable landmarks such as the Lighthouse overlooking Pyramid Cove, and the prominent geographical features of Pyramid Head and China Point. This area reflects the mid-century development of offshore military infrastructure, where the natural landscape of White Rock and Mosquito Cove met the requirements of maritime navigation and defense systems.
