The mountain is the third-highest in the Western Hemisphere, and is located about 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) ==Elevation== A 1994 Argentine expedition claimed —using GPS technology available at the time— that the elevation of Monte Pissis was , 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 performed a DGPS survey of Pissis' summit and found the elevation to be . In 2006 an international expedition surveyed the height on the summit, and found results in agreement with an elevation around . 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 and the latter 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Monte Pissis」の詳細全文を読む スポンサード リンク
