Nevado Ojos del Salado ("snowy eyes of the salty river") is the highest volcano on earth at 6,891 m (22,608 ft), geologically a stratovolcano located in the Andes on the Argentina-Chile border. This is also the second highest mountain in the Western Hemisphere and the highest in Chile.
The highest elevation of the Western Hemisphere is the Aconcagua located about 550 kilometres (342 mi) to the south in Mendoza Province, Argentina, at 6,962 m (22,841 ft).
It has two summits one located in Copiapo, Chile and the other in Catamarca, Argentina; both at the same elevation.
The volcano has very dry conditions with snow only remaining on the peak during winter. There is also a permanent crater lake about, on the east face of Ojos del Salado, 100 metres (300 ft) in diameter, with an area of 0.785 hectares, at an elevation of 6,390 m (20,960 ft), making it the highest lake in the world registered so far.
The first registered ascent was made in 1937 by Jan Alfred Szczepański and Justyn Wojsznis, members of a Polish expedition in the Andes.
Its name stands for the enormous deposits of salt that, in the form of lagoons or “eyes”, appear in its glaciers.
According to a study of the Smithsonian Institution's Global Volcanism Program, the most recent known eruption was around 1300 years ago. However, there is also some evidence for a minor ash emission in 1993. It must be also taken into account the presence of fumaroles high on the mountain and recent-looking lava flows, that maintain its categorization as "active."
On Saturday, April 21, 2007, Chileans Gonzalo Bravo G. and his co-driver, Eduardo Canales Moya, claimed to have broken the New High Altitude World Record aboard a vehicle, when they reached 6,688 m (21,942 ft) in altitude, on Ojos del Salado. This record was certified by the Guinness World Record on July 2007.
