1943 Map of San Clemente Island South

About this map

The southern reaches of San Clemente Island are dominated by the Naval Ocean Systems Center San Clemente Island Facility, a major military presence on this offshore territory. Mapped originally in 1943 during the war and later photorevised to show modern naval infrastructure, the landscape terminates at the sharp profile of Pyramid Head and the sheltering curve of Pyramid Cove. These coastal features, along with China Point at the southwestern tip, reveal a coastline defined by deep indentations like Mosquito Cove and isolated landmarks such as the Lighthouse. The transition from the steep inland topography to the Pacific Ocean is marked by named navigational hazards, including White Rock and Rock 12, illustrating the island's dual role as a strategic outpost and a maritime waypoint.
