A little to the southwest, still in the highlands, a splash of dark sediment from the
Lauca River is a bloodstain against the dazzling white of the 960-square-mile Salar
de Coipasa. Bolivia 's salt flats, the world's largest, are ghostly remnants of evapor-
ated lakes, trapped in closed basins. Today, the flats' thick, remarkably even crust at-
tracts flamingos, which thrive in high salinity environments—and their highly reflective
vast surfaces are perfect for calibrating the altimeters of satellites, providing far more
accurate elevation readings than any ocean.
