Paleo Slide Set: Low Latitude Ice Cores: High Resolution Records of Climatic Change and Variability in the Tropics and Subtropics
Peruvian altiplano
The Peruvian altiplano is a high plateau ranging in altitude from 3500 to over 4000 meters above sea level. Though the altiplano is a cold, harsh environment, large herds of hardy llamas such as these hint at the richness of South America's high grasslands. The Quelccaya ice cap rises in the background, 55 km2 of ice that provides important clues on climatic change and variability in the South American tropics. The ice sheet's summit elevation is 5670 m and its maximum summit thickness is 164 m.
