Which mountain is the world’s fourth-highest peak?

Lhotse is the world’s fourth-highest peak.

Lhotse rises to 8,516 metres and is connected to Mount Everest by the South Col. Its name means “South Peak” in Tibetan, describing its position south of Everest. The mountain lies on the Nepal–China border in the Himalayas.

The main summit was first climbed on 18 May 1956 by Swiss climbers Ernst Reiss and Fritz Luchsinger. Lhotse’s imposing south face is one of the largest and steepest mountain faces in the world, making it a serious technical challenge even for climbers who have experience at extreme altitude.

Lhotse is sometimes mistaken for part of Everest because the two mountains share the South Col route. They are separate peaks, however, with distinct summits and climbing objectives. Lhotse also has subsidiary summits called Lhotse Middle and Lhotse Shar.
