Witness the extraordinary life of Dr. Lonnie Thompson, an explorer who went where no scientist had gone before and transformed our idea of what's possible. Daring to seek Earth’s history contained in glaciers atop the tallest mountains in the world, we see the front lines of climate change, to recover these priceless historical records before they disappear forever.
The Quelccaya Ice Cap is located 5300-5670 meters above sea level in the southeastern Andes of Peru and is the Earth’s largest tropical glacier. The observed change in surface elevations on QIC is similar to those seen at other glaciers. However, the second-largest mountain range in Peru, the Cordillera Vil-canota (CV), south-east of the Cordillera Blanca, has received much less attention to date. Consequently, little is known about the timescales and equilibrium conditions of the vast majority of tropical Andean glaciers, and how climate variability affects their mass balances. In Peru, most studies have focused on glaciers in the Cordillera Blanca, which represents the largest mountain range in the tropics.
