The time capsule in the salt flat

There is a place in northern Chile, 3,500 meters above sea level in the Andean Altiplano, where almost nothing survives. The Salar de Pajonales is a salt flat of savage extremes temperatures swinging from -23C to 26C, solar radiation among the highest measured anywhere on Earth, annual rainfall that barely registers, and winds that rip across the surface at over 100 kilometers per hour. And yet, life is there.
