Guallatiri, Chile

Guallatiri is a stratovolcano in northwestern Chile near the city of Putre, rising to about 6,071 meters in the Cordillera Occidental. Its summit features twelve active fumaroles that regularly release sulfuric gases.

The first documented ascent occurred in 1926 by German geologist Friedrich Ahlfeld, who initiated scientific study of this Andean peak. This early expedition laid the foundation for further volcanic investigations in the region.

The name comes from Aymara language and refers to Andean geese that live in the surrounding mountain areas. This connection to local wildlife appears in the names of many places throughout the region.

Visiting requires advance permission from local authorities and organized transportation from Putre to a base camp at about 5,100 meters. The high altitude and remote location require good physical preparation and proper equipment.

Snow and ice coverage above 5,500 meters has noticeably decreased over the past century. This change has visibly altered the mountain's appearance and exposed new rock areas for climbers.
