The extensive sediment fill of Lake Titicaca and the Salar de Uyuni, the fluvial and lacustrine sediments deposited in the lake's only distributary (the Rio Desaguadero), and the sediments of the lake's major tributaries contain the paleoclimate record of much of tropical South America. With this research, we are interpreting that record and providing needed information about terrestrial tropical climates. In addition, by studying river valleys that have been occupied by humans for over 8000 years, we are working toward an understanding of the impact of climate change on human cultures (and the influence of human activities on Altiplano landscapes).
