1943 Map of San Clemente Island Central

About this map

San Clemente Island appears here as a rugged landscape defined by maritime defense and isolation. Originally mapped by the Army Map Service during the height of the Second World War, the sheet highlights the specialized infrastructure of the Naval Ocean Systems Center Facility. This military presence is anchored by a Landing Strip situated atop the high coastal plateaus, overlooking the steep descents toward the shoreline. The island's perimeter is marked by distinct topographical landmarks such as Eel Point and Black Point to the north, while the southern reaches lead toward the isolation of Lost Point. Between these headlands, Seal Cove provides a break in the sheer cliffs, illustrating the island's complex coastal geometry as it stood in the mid-20th century before late-Cold War revisions were recorded.
