Half of the meltdown, as measured by volume, took place before 1980. The final meltdown after 1980, due to missing precipitation and the warm phase of El Niño, resulted in the glacier's disappearance in 2009. The glacier was located about 30 kilometers (19 mi) from

November to March. Since 2009, skiing is restricted to a 600-foot (180 m) stretch that sometimes receives sufficient snowfall for a run during the winter. The mountain is also popular with amateur mountaineers, as the road stops only 200 metres (660 ft) from the summit.

The rope tow, the first in South
America, was built in 1939 using an automobile engine; it was housed in the site's original clapboard lodge, and is now inoperable. The road to the base of the 200-meter (660 ft) drop is reached by a narrow road, also built in the 1930s. Traditionally, due to the

Scientists at the Mount
Chacaltaya Laboratory started measuring the Chacaltaya glacier in the 1990s. Predicted at that time to survive until 2015, the glacier melted at a faster rate than expected. By 2009, it had been reduced to a few small patches of ice and snow near the top of the mountain.
