Licancabur's perfect cone, Lascar's active crater, Acamarachi's broad shoulders — they line the eastern horizon like sentries guarding a basin that has no outlet, no river flowing to the sea, no escape for the water that trickles in from snowmelt and springs. Everything that enters stays, and over millions of years that patient accumulation has produced Chile's largest salt flat and one of the richest lithium deposits on the planet. What looks from the air like a white void is, in geological and economic terms, anything but empty.

Salar de Atacama: A Basin That Keeps Its Secrets

The Andes wall it in from the east, while the Cordillera de Domeyko seals the west. The volcanoes along the eastern rim — Licancabur, Acamarachi, Aguas Calientes, and Lascar, one of ...

The brines beneath the salt crust contain some of the highest concentrations of lithium found anywhere, and as of 2017 the salar provided roughly 36 percent of the world's lithiu...

The town of San Pedro de Atacama, 55 kilometers north of the salar, has been a human settlement for thousands of years, and the indigenous communities maintain a complex an...

Andean flamingos wade through the shallow lagoons that form along the salar's edges, their pink plumage incongruous against the white and brown landscape. Laguna Cejar, near the salar's margin, is so saline that swimmers ...

Salar de Atacama: The View from Overhead

Photo credit Francesco Mocellin, CC BY-SA 3.0. From altitude, the Salar de Atacama reads as a vast white patch set between two mountain ranges, its edges irregular where alluvial fans push sediment inward from the surrounding slopes. The evaporation ponds of the lithium operations stand out as geometric rectangles of varying ...
