Chomo Lonzo, Mountain summit in Shigatse, China

Chomo Lonzo is a mountain in the Mahalangur Himalaya of Tibet, 5 km northeast of Makalu, with three summits: the main southern peak at 7,804 m, a central peak at 7,565 m and a north peak around 7,200 m. The main and central peaks are joined by a saddle at about 7,250 m, the central and north peaks by one at about 7,050 m. Its northwest ridge drops 2,000 to 2,500 m in steep walls of smooth granite.

The mountain was first climbed in 1954 by French mountaineers Jean Couzy and Lionel Terray, who used the southwest ridge route. This ascent marked a key milestone in exploring this Himalayan region.

The name Chomo Lonzo comes from Tibetan and means goddess of the bird, as the mountain's shape resembles a bird with spread wings when viewed from the east.

Climbers typically choose the months of April through June and September through November for climbing attempts, when weather conditions are more favorable. During these periods, climbers have the best visibility and more stable snow and ice conditions.

The peaks of this mountain sit unusually close together and are joined by very narrow ridges. This tight connection between the summits makes climbing on this mountain somewhat distinctive compared to more isolated Himalayan peaks.
