The steep coastal escarpments of San Clemente Island drop directly into the Pacific Ocean in this 2018 topographic study. The map focuses on the eastern shoreline of the central portion of the island, where high ridges and deep drainages characterize the terrain before it meets the sea. This specific quadrangle captures the dramatic transition from the island's interior elevations down to the water line, showing a landscape defined by sharp contour intervals and a complete absence of developed infrastructure or named inland settlements. It provides a technical record of the island's natural coastal geography as managed by the U.S. Geological Survey in coordination with the Department of the Interior.
