Isla San Luis, seen here from the SW with a large rhyolitic lava dome near the center, is the largest of the seven Encantada islands in the northern part of the Gulf of California. The roughly 180-m-high island lies 3 km off the eastern shore of Baja California. An older lava dome forms the NE tip of the island, and an eroded tuff ring lies at the SE tip. The lava dome seen here in the center of the island was constructed within a tuff ring and is the youngest volcanic feature.
