Haritashiya et al (2009) examined fluctuations of 30 Wakhan Cooridor glaciers from 1976-2003. …

In this post glaciers in the remote area around Yajun Peak in the Hindu Kush 150 km northeast of Bagram Airbase and 75 km west of the Pakistan Border are examined. Landsat …

Zemestan Glacier, Afghanistan Retreats

The Wakhan Corridor in Afghanistan is not easy to get to, as a result field study of its glaciers are quite limited. This is where the Global land ice Monitoring System (GLIMS) comes in. GLIMS acquires satellite imagery of glaciated areas, making these images available to researchers and processing them to an extent for inventory purposes. GLIMS is led by Jeff Kargel at the University of Arizona. In the Wakhan …
