The Pacific Ocean dominates this offshore survey southwest of San Nicolas Island, highlighting a maritime boundary of California. Located within Ventura Co, the map focuses on the open sea and the bathymetry of the Pacific shelf rather than terrestrial landmarks. The primary feature of interest is the maritime county line, which arcs across the vast waters of the Pacific Ocean to define the administrative reach of the coastal mainland. This 2015 edition serves as a clear record of modern maritime boundaries and the geographic extent of California's offshore territory in a region typically characterized by its isolation from the mainland coast.
