The sites — a rock shelter with traces of Ice Age campfires and rock art, and an open-air workshop with stone tools and fragments — are located nearly 14,700 feet (4,500 meters) above sea level and were occupied roughly 12,000 years ago.
The discovery, which is detailed today (Oct. 23) in the journal Science, suggests ancient people in South America were living at extremely high altitudes just 2,000 years after humans first reached the continent.
After years of searching around the plateau, the researchers found a rock shelter with two alcoves, ceilings blackened with soot and walls decorated with rock art. The site also showed evidence of burnt detritus from ancient people's campsites. The rock shelter was used for thousands of years, starting around 12,400 years ago, and may have been a temporary base camp where herders sheltered from the rain, Rademaker said.
The coastal obsidian point likely came from a nearby outcropping, which would've been an ancient open-air workshop at the time, the researchers said. The workshop contained hundreds of ancient tools, from spear points to scrapers to bifaces, or hand axes, some of which dated to 12,800 years old. The researchers also found large mammal bones from vicuña, the wild ancestors to alpacas, similar animals called guanacos, and taruca deer.

I imagine they would have had to have adapted by this point. Some people start to suffer symptoms of altitude sickness as low as 8,000 feet and this settlement was found at a height nearly twice that.
