Volcán Lanín is a large conical late-Pleistocene to Holocene stratovolcano along the Chile-Argentina border. The beautifully symmetrical, 3737-m-high Lanín, seen here from the Chilean side, rises 2500 m above its base. A small lava dome at the summit fed blocky lava flows to the north. A postglacial tuff ring (Volcán Arenal) is located below the SW flank of Lanín in Argentina. A younger lava flow from Lanín covers deposits of Volcán Arenal and extends south into Lago Paimún. No reliable reports of historical eruptions from Lanín are known.
