About this map

San Nicolas Island is the focus of this 1993 compilation, which details the isolated terrain and military administrative boundaries of this Ventura County outpost. Defined largely as a U. S. Naval Reservation, the map highlights the infrastructure of the base, including a prominent Landing Strip and protected anchorages like Dutch Harbor.

The inclusion of offshore data, such as Begg Rock and various protraction diagrams like Protraction Diagram 6B, reflects the map's use for managing the Outer Continental Shelf and the Pacific Ocean waters surrounding the island. This survey synthesizes aerial photography and older topographic data to provide a clear view of the island's Indefinite Boundary and its role in naval operations during the late twentieth century.
