About this subject

Aconcagua is the highest peak in the Southern Hemisphere and the Americas, standing 6,961 meters tall. Located in Mendoza Province, Argentina, it is part of the Andes mountain range, specifically the Principal Cordillera. Its geological formation dates to the Cenozoic era, resulting from the subduction of the Nazca Plate beneath the South American Plate. The name Aconcagua comes from the Mapuche "Akon Kahuak", meaning "stone sentinel".

The mountain is an iconic destination for climbers worldwide, with the Normal Route (Northwest Route) being the most popular, requiring no advanced ice climbing skills but demanding physical endurance to cope with extreme altitude. The first recorded ascent was in 1897 by Matthias Zurbriggen, a Swiss guide leading a British expedition. Today, about 3,500 people attempt the summit annually, with a success rate of approximately 30%.

Besides mountaineering, Aconcagua attracts researchers due to its diverse geology, including sedimentary, igneous, and metamorphic rocks. Aconcagua Provincial Park, created in 1983, protects the area, which harbors glaciers such as the Polish Glacier and Horcones Glacier. Wildlife includes condors, guanacos, and the rare vicuña. The best climbing season is November to February, summer in the Southern Hemisphere.

Interestingly, Aconcagua is not a volcano despite its appearance; it is a mountain formed by faulting. Extreme altitude causes altitude sickness (soroche) in many visitors, requiring gradual acclimatization. The speed ascent record is 11 hours and 52 minutes, set by Ecuadorian runner Karl Egloff in 2015.
