Pemba Dorjie crossing a crevasse on the Khumbu Icefall. The Khumbu Glacier moves an estimated 0.9 to 1.2 m (3 to 4 ft) down the flank of Mt. Everest every day. Ice entering the fall takes approximately 4.3 years to emerge at the base, which is 600 metres (2,000 ft) lower and 1.5 kilometres (1 mi) away horizontally.

Commonly house-sized or larger, they are dangerous to mountaineers, since they may topple with little warning. Even when stabilized by persistent cold weather, they can be an ...
Guides can, for example, set fixed lines of rope for others to use, organize rescues in times of trouble, or use communication tools to call in helicopter evacuations. [1] [2] Another job on Mount Everest is as an "icefall doctor" using ladders and ropes to make a path across the Khumbu Icefall, which guides might do themselves or delegate to others. [3]
Most glacier ice flows at speeds of a few hundred metres per year or less. However, the flow of ice in an icefall may be measured in kilometres per year. Such rapid flow cannot be accommodated by plastic deformation of the ice. Instead, the ice fractures, forming crevasses. Intersecting fractures form ice columns or seracs. These processes are ...
