Illiniza Sur, seen here from the Interandean valley to its east, is the highest of the twin peaks of Illiniza volcano. A lava dome on its southern flank, Rasuyacu, erupted during the Holocene. Illiniza itself may have had relatively youthful eruptions, although none have been dated. Photo by Lee Siebert, 1978 (Smithsonian Institution).
