Glaciers around Mt. Everest: the debris-covered glaciers of Khumbu

Indoor Event, 7pm
Great North Museum, Newcastle

Valley glaciers of Khumbu Himal are characterized by irregular relief on debris-covered surfaces, due to the high relief, rockfall and differential ablation. Many of their sources are hanging, frozen to steep cliffs. They are shrinking by downwasting more than by frontal retreat. As ablation is fastest just below the snowline, before debris cover builds up, more glaciers will split into hanging and buried sections, which will survive for centuries. Dr Ian Evans, Emeritus Reader in the Department of Geography at Durham University, will explain the workings of the glaciers around Mount Everest.
