Pacific Ocean waters dominate this maritime survey of the northern offshore reaches of the San Nicolas Island region. Produced by the U.S. Geological Survey, this sheet captures the open sea and the extreme northwestern coastal fringe of the island where the land meets the surf. The bathymetric and topographic detail at the bottom of the map shows the transition from the marine environment to the island's elevation, providing a specialized view of the coastal geography of Ventura County. Because the land area is minimal, the focus is squarely on the coastal boundary and the vast nautical expanse surrounding this remote California territory.
