Western Cwm

The Western Cwm extends as a broad, flat glacial valley basin at elevations between 6000 and 6800 meters, terminating at the Lhotse Face of Mount Everest.

George Leigh Mallory identified and named this valley during the British Reconnaissance Expedition of 1921, marking the first exploration of Everest's upper sections.

The name Cwm originates from Welsh language terminology, reflecting the European mountaineering influence on Himalayan geography through early expeditions and discoveries.

Mountaineers must navigate through massive lateral crevasses in the central section by moving toward the Nuptse corner to access the upper sections of the valley.

The surrounding snow-covered slopes create a natural solar reflection effect, generating higher temperatures within the valley despite its extreme altitude position.
