Nevado de Acay

Nevado de Acay is a 5,950-metre-high (19,520 ft) mountain in Argentina. It is a volcanic intrusion that formed during the Miocene and was later exposed. The intrusion is formed by monzonite and is associated with a fault system that also connects to neighbouring volcanoes. While not presently glaciated, it contains a seasonal snowpack and is the source of several streams and rivers, including the Rio Salado. A number of archeological sites have been found on Nevado de Acay and mining activity occurred there until recent times.
