Near the western point of the island is Smith Volcano, also known as Mount Babuyan, about high. In the middle of the island and east-southeastward from Smith is Babuyan Claro, also known as Mount Pangasun, about high, between which the mountains are much lower, so that from a considerable distance eastward it appears as a round mountain with a detached hillock northward. There are three other volcanic cones with no historic eruptions on the island - Cayonan, Dionisio and Naydi.
