Lake Ballivián
Lake Ballivián (Spanish: Lago Ballivián) is the name for a Pleistocene high lake stage of Lake Titicaca that existed about 191,000 BP. It was a Pleistocene lake that occupied what is now the northern Altiplano in the Andes Mountains of South America. At its deepest, the level of Lake Ballivián is estimated to have been at about an elevation of 3,860 meters (12,660 feet) above sea level. This is about 50 meters (160 feet) above the present day level of Lake Titicaca. Lake Ballivián possibly was the chronological equivalent of Lake Escara, which might have had an elevation of 3780 meters above sea level, within the southern Altiplano[1]
Within the Lake Titicaca Basin, Lake Ballivián was succeeded in time by later Pleistocene lakes, Lake Minchin and Lake Tauca, and modern day Lake Titicaca. Evidence of this and other now-vanished lake are still visible nowadays. Such features as lake strandlines, wave cut benches, lacustrine sediments, algal mounds may be found above the present level of Lake Titicaca.[1]
