1943 Map of San Clemente Island North

About this map

San Clemente Island Naval Ocean Systems Center occupies the northern reaches of this Pacific outpost, revealing the strategic infrastructure of the mid-20th century. The landscape is dominated by the Landing Field situated across The Isthmus, a narrow corridor flanked by Northwest Harbor and West Cove. The presence of several Lighthouse symbols and a Water Tank near Wilson Cove underscores the logistical requirements of maintaining a remote naval presence. Beyond the military installations, the terrain is defined by coastal features such as the Shifting Sands and prominent elevations like North Head. Off the northwestern coast, Castle Rock and West Rock stand as hazards in the Pacific Ocean. This survey, updated with 1980 photorevisions, documents the hardening of the island's coastal defenses and support facilities.
