Aconcagua is the “Colossus of America,” situated in the Mendoza Province of Argentina. Geographically, it is the highest peak outside of Asia. Although it is located within the Andean volcanic belt, Aconcagua itself is a structural mountain formed by the subduction of the Nazca Plate, which uplifted the crustal blocks. Its summit is capped by glaciers and it serves as a massive geographical landmark. For mountaineers, it is one of the “Seven Summits.” Its height and location make it a primary influence on regional weather patterns, creating a formidable barrier to moisture from the Pacific.
