Lhotse is the fourth highest mountain in Earth with an altitude of 8516 meters.

It did not have a local name neither in tibetan nor in nepali. As this mountain is south of Everest, and links to it through its col, in 1921 Howard Bury named it south peak, which in Tibetan is Lhotse.

In 1956 a Swiss team arrived in Nepal with the intention to do the second climb to Everest, but they also had a permit for Lhotse. This expedition consisted of eleven Swiss mountaineers and the leader was Albert Eggler. The route to follow was clear: to go through the kumbu glacier up to the south col of Everest and do the attempt from there to the summit. The 18th of May 1956 they reached the sharp and small summit.

Nowadays Lhotse has five routes on its south face and just one on the west face.
