South Summit

The South Summit is a subsidiary peak of Mount Everest in the Himalayas between the South Col (at 7906 m) and the main summit (at 8849 m) above sea level. Although the South Summit's elevation of 8749 m is higher than the second-highest mountain on Earth (8611 m K2), it is not considered a separate mountain as its topographic prominence is only 11 meters.

Overview
The South Summit is a dome-shaped peak of snow and ice approximately 130 m distant from the summit of Mount Everest and 100 m below it, connected to it by the Cornice Traverse and Hillary Step. It was first climbed by Charles Evans and Tom Bourdillon of the 1953 British Mount Everest expedition on 26 May 1953. They arrived at 1 pm, too late to continue on because of problems with Evans' oxygen set. Three days later, on 29 May, Edmund Hillary and Tenzing Norgay passed over the South Summit en route to achieving the main peak.

History
On reaching the South Col in 1953, expedition leader John Hunt was struck by the sight, writing "Above us rose the South Summit of Everest ... an elegant snow spire, breathtakingly close yet nearly 3000 feet above our heads ... none of us had been prepared for any spectacle quite so sharp, quite so beautiful as this. To me it seemed that a new and unsuspected peak of alpine stature stood above the South Col."

A geologist with the 1965 Indian Everest expedition discovered a deposit of fossils of seashells in limestone about 100 feet above the South Summit.

Recounting his first ascent of Mount Everest without supplemental oxygen in 1978, Reinhold Messner described the South Summit as "quite a milestone for me".

During the 1996 Mount Everest disaster, mountain guide Rob Hall and three other people died at the South Summit while descending from the main summit in an unexpected blizzard. Hall survived overnight, and established radio contact the following day, but froze to death later that day, May 11, 1996. His body remains on the South Summit.

The south summit is a popular place for climbers to pause, change oxygen bottles, and turn around if necessary. From this location the cornice traverse, Hillary Step, and summit can be seen in clear weather.
