A vigorous steam plume rises from the summit ridge of Volcán Guallatiri, one of northern Chile's most active volcanoes. The ice-clad stratovolcano is seen here from the north and lies at the SW end of the Nevados de Quimsachata volcano group. The 6071-m-high Guallatiri is capped by a central dacitic dome or lava complex, with the active vent situated at its southern side. Minor explosive eruptions have been reported from Guallatiri since the beginning of the 19th century, and intense fumarolic activity continues.
