Description
The two large salt flats of the Bolivian Altiplano, the Salares of Coipasa (pictured) and Uyuni, are the remnants of a vast Ice Age freshwater lake, Lago Minchin. Due to low rainfall, the absence of tributaries and the extreme dryness of the air, the former freshwater lakes have evaporated into shallow lagoons and salt flats, their shores lined with deposits of common salt. Cut into blocks, the snow-white salt – considered to be of exceptional purity – is transported by lorry to the areas where it is used. - Book: Picture 159 - Chile - 1976
