Volcán Llullaillaco (6,739m; 24°43'13.81"S, 68°32'12.78"W) is located on the border between Chile and Argentina in the Northern Andes and was a sacred mountain to the Inca, who are confirmed to have ascended it more than 500 years ago. In February 2021, the archaeologist and climber Christian Vitry along with Adrián Gandino, Gerardo Casaldi, and Federico Sánchez (all from Argentina), reached the summit by what is likely a new route up the south face, following an icy couloir with some easy mixed terrain, starting from a high camp at the foot of the couloir. They called the 800m route Huamán, which means “hawk” in Quechua. On the same expedition were Julio Altamirano, Sergio Ceruti, Martín Giraudo, Eduardo López Jordán, and Emilio González Turu. On January 30, the 72-year-old Ceruti ascended a minor volcano, thought to be unclimbed, to the south of Llullaillaco; he named it Chungara (5,200m).
