They were seated, clothed, surrounded by gold and silver figurines, and perfectly preserved by 500 years of cold, dry, oxygen-poor air. The Inca had brought them here -- to the highest archaeological site on Earth, at roughly 6,715 meters above sea level -- as offerings to the mountain gods. The volcano that held them is the second-highest active volcano in the world, a 6,723-meter giant straddling the border between Argentina and Chile. Its Quechua name likely means "deceitful water," a reference to snowmelt that flows down its slopes only to vanish into the parched soil of the Puna de Atacama.

They sat in the positions in which they had died, wrappe...

Three roads converge from the surrounding salt flats at a tambo -- an inn with numerous buildings -- at roughly 5,200 meters on the northeastern flank. From there, a ceremonial path ascends the ...

The oldest rocks date to roughly 1.5 million years ago. During the first stage, lava flows extended up to 20 kilometers from the summit, building the bulk of the edifice that still makes up about 70 percent of its...

Despite conditions among the harshest on the planet -- intense UV radiation, daily freeze-thaw cycles, and soils nearly devoid of organic matter -- life persists on Llullaillaco. Between 4,400 and 4,900 meters, a sparse steppe of cushion plants and shrubs clings to the slopes, re...

Photo credit Lion Hirth (User:Prissantenbär), Public domain. The first recorded Western ascent came in 1952, when Chileans Bion Gonzalez and Juan Harsheim reached the summit. But the Inca had climbed it centuries before them, building on the mountain with primitive technology at altitudes that challenge modern mountaineers equipped with su...
