...Christa Placzek; Jay Quade; P. Jonathan Patchett Abstract Large paleolakes (∼33,000–60,000 km 2 ) that once occupied the high-altitude Poopo, Coipasa, and Uyuni Basins in southern Bolivia (18–22°S) provide evidence of major changes in low-latitude moisture. In these now-dry or oligosaline basins...

... becoming salars (Chong-Diaz, 1988; Grosjean, 1994 ,1995). Laguna Chungará lies at the northeastern edge of the Lauca basin, which is the westernmost and highest fluvio-lacustrine basin in the Altipiano ( Figure 1 ). The Lauca basin is filled with a sequence of some 120 m of upper Miocene-Pliocene...
