Colachi

The Colachi volcano rises to an elevation of 5,631 meters above sea level, featuring a degraded summit crater and visible lava flows on its eastern flank.

The volcano developed during the late Miocene period upon elevated welded ignimbrites, forming part of a complex system with neighboring Acamarachi volcano.

The mountain area holds traditional value for indigenous communities of northern Chile, who maintain connections to the volcanic landscapes of Antofagasta.

The remote location and extreme altitude of Colachi require specialized equipment, extensive planning, and proper acclimatization for any climbing attempts.

A substantial silicic lava flow covers 7 square kilometers between Colachi and Acamarachi, displaying characteristic glassy formations typical of regional volcanic deposits.
