Volcán Guallatiri rises to the SSE beyond Laguna Chungará, and steam rises from a prominent fumarole near its summit. The symmetrical ice-clad stratovolcano lies at the SW end of the Nevados de Quimsachata volcano group just west of the border with Bolivia and is capped by a central dacitic dome or lava complex. Thick lava flows can be seen on its lower northern and western flanks. Minor explosive eruptions have been reported from Guallatiri since the beginning of the 19th century, and intense fumarolic activity continues.
