Historical & Ecological Origin

Aconcagua is a non-volcanic mountain formed by the uplift of the Andes mountain range during the Andean orogeny, a result of tectonic plate collision. Its geological history dates back millions of years. The mountain's ecological classification is alpine desert, characterized by extreme altitude, low temperatures, and high solar radiation.
