2021 Map of San Clemente Island Central OE E

About this map

The coastal elevations of the Channel Islands meet the Pacific Ocean in this 2021 digital survey of California's offshore territory. The map focuses on a dramatic section of the steep marine escarpment, where land rises sharply from the sea to a series of interior ridges and plateaus. A prominent shoreline landmark, White Rock, anchors the coastal profile where the rugged maritime topography descends into the surf. The tightly packed contour lines along the western edge of the sheet illustrate the extreme verticality of this island landscape, highlighting the natural barriers that define the isolated character of these landforms. This modern geographic study provides a precise record of the current coastline and terrain before it gives way to the deep open water of the Pacific.
