The Tupungato is an imposing mountain on the border between Argentina and Chile with an altitude of 6,550 m. It lies about 50 km south of the Aconcagua in the Argentine province of Mendoza. He is one of the highest volcanoes in the world. Its smaller, but more active brother Tupungatito is about 6000 meters high and is just 6 km away in the south-west. Here was the last eruption in 1987 instead.

On August 2, 1947 fell on the Argentine side of the Avro 691 Lancastrian Tupungato of British South American Airways named Star Dust and remained lost for over 50 years (see Star -Dust - crash). It was only on 23 January 2000 parts of the wreck were discovered by a group of climbers.
