This article needs additional citations for verification. (January 2023) |
The Western Cwm (/kuːm/) is a broad, flat, gently undulating glacial valley basin terminating at the foot of the Lhotse Face of Mount Everest. It was named by George Mallory when he saw it in 1921 as part of the British Reconnaissance Expedition that was the first to explore the upper sections of Everest, searching for routes for future summit attempts;[1] A cwm is a valley fully enclosed by mountains, from the Welsh word for "valley".
The Western Cwm is traversed by climbers using the
Base Camp
.
The snow-covered, bowl-shaped slopes surrounding the Western Cwm reflect and amplify
solar radiation, warming the valley basin despite its high elevation of 6,000 m (20,000 ft) through 6,800 m (22,300 ft).[2]
