About this subject

Aconcagua is a mountain located in Mendoza Province, Argentina, in the Andes range. At 6,961 meters (22,837 feet) above sea level, it is the highest peak in the Western and Southern Hemispheres, and the tallest mountain outside Asia. Its geological formation dates back to the Cenozoic Era, resulting from the subduction of the Nazca Plate beneath the South American Plate. Although of volcanic origin, Aconcagua is not an active volcano; its composition includes sedimentary and igneous rocks, with glaciers such as the Polacos and Horcones Inferior.

Thousands of adventurers attempt to climb it every year, mainly during the austral summer (December to February). The normal route via the Northwest Route is considered non-technical in terms of climbing, but the main challenge is extreme altitude, which can cause acute mountain sickness. The first recorded successful ascent was in 1897 by Swiss mountaineer Matthias Zurbriggen, part of an expedition led by British climber Edward FitzGerald. Since then, Aconcagua has become one of the most iconic mountaineering destinations worldwide.

Culturally, the name "Aconcagua" possibly derives from Quechua "Ackon Cahuak," meaning "Stone Sentinel" or "Stone Guardian." For indigenous peoples, the mountain was considered sacred, and archaeological evidence, such as Inca mummies from sacrifices, has been found on its slopes. Today, the area is protected by Aconcagua Provincial Park, which preserves high-altitude ecosystems and shelters species like vicuñas and Andean condors.

Climbing Aconcagua requires physical fitness and proper acclimatization. Several routes exist, with the most popular being the Normal Route, which takes about 20 days. The base camp Plaza de Mulas (4,370 m) is the main starting point for expeditions. The mountain also hosts records, such as the fastest ascent and the complete traverse of the Andes on skis.
