Abstract
A diatom study, carried out on a core recovered in the Southern Altiplano ( Coipasa salt lake 19 degrees S, 68 degrees W) currently almost completely d ry, shows that during the last glacial maximum the Coipasa salar was entire ly occupied by a large shallow lake. Available data for the northern Altipl ano (Lake Titicaca, 16 degrees S, 69 degrees W) indicate a water level 17 m lower than today. This opposition is explained by decreased tropical preci pitations whose effects registered by Lake Titicaca were obliterated in the Coipasa salar by increased winter precipitation.
