Aconcagua rises in the Principal Cordillera of the Andes in Mendoza Province, Argentina, reaching a summit elevation of about 6,967 meters, the highest mountain in the Americas, the highest peak outside Asia, and the highest point in both the Western and Southern Hemispheres. It is a non-volcanic peak raised by Andean tectonic uplift, the second-most topographically prominent peak in the world after Everest, and one of the Seven Summits, the highest peaks on each continent. This entity documents Aconcagua specifically as a geological formation, a distinct facet from its treatment as a place and landform on the Geography Atlas; this entry covers the mountain's tectonic origin and its standing as the highest peak of the Americas and of the Southern and Western Hemispheres.
