About this map

San Clemente Island appears here as a specialized military and research landscape in the Southern California Bight. This 1980 study, revised from earlier aerial photography, highlights the strategic role of the Naval Ocean Systems Center Island Facility and the infrastructure required for offshore operations, including a prominent Landing Strip. The map detail captures the island's coastline from the northernmost North Pt down to the southern reaches of Pyramid Cove.

Surrounded by the Outer Santa Barbara Passage and the Gulf of Santa Catalina, the terrain is marked by coastal features such as Seal Cove, China Pt, and the distinctive Balanced Rock. This sheet provides a detailed record of the island's isolation and its topography during the late twentieth century, showing the intersection of naval activity and the natural geography of Los Angeles County in the open Pacific Ocean.
