Salar de Talar is a 46 square kilometres salt flat located in the high puna of northern Chilean Andes, at an altitude of 3,950 m. It is part of a series of salt lakes and salt flats located at the foothills of a chain of volcanoes stretching along the eastern side of the much greater Salar de Atacama.
The closed drainage basin of Salar de Talar encompasses about 476Â km and is adjacent to other endorheic basins, including Laguna Miscanti, Laguna Tuyajto and Salar de Capur basins. It was once filled by a 31 square kilometres (12Â mi) large lake connected to Salar Purisunchi.
