Abstract

This paper presents new proxy climate data from 2 sites in tropical South America indicating a middle Holocene dry phase, resulting in the nearly complete melting of glaciers between 8900 and 2300 C 14 yr B.P. in watersheds with headwalls of 5500 m altitude and lower in the Cordillera Real, Bolivia. Only by investigating lacustrine sediment records the AA. can determine if glaciers melted completely during the early and middle Holocene. They also discuss a possible link between observed millenial-scale shifts in the regional precipitation-evaporation balance and seasonal shifts in tropical insolation
