The locals call them Ojos de Mar - eyes of the sea - though the nearest ocean is hundreds of kilometers and a wall of Andes away. They sit at around 3,500 meters in the Puna de Atacama, and in 2009 scientists found something extraordinary living in them: stromatolites, mounded colonies of microbes among the oldest forms of life on Earth, thriving here at one of the highest elevations anyone has documented. The village that watches over them is Tolar Grande, and its own story is nearly as improbable as theirs.

Perhaps five thousand people lived here then, most of them working the railroad. Nearby,...

Through deliberate policy aimed at halting emigration, the population was coaxed back upward; by 2015 it stood at roughly 210 people. It is a small number against the immensity of the P...

To the south spreads the Salar de Arizaro, one of the largest salt flats on Earth, an expanse of blinding white crust laid down over millions of years. Rising from it, some eighty kilometers out, is the Cono de...
