Glaciers of Bhutan Himalayas
One of the highest mountain reliefs on Earth can be found in the tiny country of Bhutan. Sandwiched between eastern India and the Tibetan plateau, Bhutan hosts peaks that reach between 5,000 and 7,000 meters (16,000-23,000 feet) in height. These mountains are neighbors to Mount Everest, Earth's highest peak at 8,850 meters (29,035 feet). The impressive Bhutan Himalayas are permanently capped with snow, which extends down valleys in long glacier tongues. Because of weather patterns on each side of the Himalaya and differences in topography, the glaciers on each side of the mountain are distinctly different from one another and are likely to react very differently to climate change. This image, taken by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) in 2001, is one of a series of images used to study the glaciers of the Bhutan Himalayas. By tracking the movement of surface features like crevasses and debris patterns, Andreas Kaab of the University of Zurich measures the speed at which glaciers flow down the mountain. He found that glaciers on the north side of the range move as much as ten times faster than glaciers on the south side.
