Monte Pissis is an extinct volcano in La Rioja Province, Argentina. The mountain is the third-highest in the Western Hemisphere, and is located about 550 km (340 mi) north of Aconcagua. Monte Pissis is named after Pedro José Amadeo Pissis, a French geologist who worked for the Chilean government. Due to its location in the Atacama Desert, the mountain has very dry conditions but there is an extensive glacier (with crevasses, which is unique in the region)
A 1994 Argentine expedition claimed —using GPS technology available at the time— that the elevation of Monte Pissis was 6,882 m (22,579 ft), higher than Ojos del Salado. Ten years later, with the use of higher precision systems, several other surveys proved that those measurements were inaccurate: in 2005, an Austrian team performed a DGPS survey of Pissis' summit and found the elevation to be 6,793 m (22,287 ft). In 2006 an international expedition surveyed the height on the summit, and found results in agreement with an elevation around 6,800 m (22,300 ft). This was later confirmed by a 2007 Chilean-Argentine-European expedition, which surveyed both Ojos del Salado and Monte Pissis and provisionally found the former to be 6,891 m (22,608 ft) and the latter 6,793 m (22,287 ft)
Until recently, this mountain had received very little attention. The first successful recorded ascent was achieved in 1937 by Polish climbers Osiecki and Szczepanski. The mountain was not climbed again until 1985.
The opening of mining in the area has resulted in the construction of basic roads in the last 15 years. This has developed the tourism in the Atacama Desert and now more people ascend the mountain, usually with a previous stop in Fiambalá to organise the climb. Approaching it from neighboring Chile is also possible but involves a longer way.
