Located at the southern end of the internally-drained Altiplano, the Salar de Uyuni is the largest salt flat on Earth. Millennia of wet and arid periods on the Altiplano are recorded in the thick Quaternary lake sediment of the salar. Accordingly, the Salar de Uyuni continues to be the focus of paleoclimate efforts by researchers worldwide. One such example is the presence of coral within limestone beneath a paleo-lakeshore terrace.
