Isla San Luis lies across a narrow channel from the NE coast of Baja California (in the background). A rhyolite obsidian dome is in the center of the small island. An older dome forms the northern part of the island (foreground) and is partially mantled by ash and pumice from the central dome. An eroded tuff ring, Plaza de Toros, occupies the SE end of the island.
