Lhotse is the fourth highest mountain in the Himalayas. Its long east-west crest is located immediately south of Mount Everest, and the summits of the two mountains are connected by the South Col, a vertical ridge that never drops below 8,000m. (map). Sometimes mistakenly Lhotse has been identified as the south peak of the Everest massif. In addition to the main summit, there are two subsidiary peaks, Lhotse Shar, which is immediately east of the main summit, and Nuptse, a high peak on the mountain's west ridge.
The main summit of Lhotse was first climbed on May 18, 1956 by the Swiss team Ernst Reiss and Fritz Luchsinger. On May 12, 1979, Zepp Maierl and Rolf Walter of Austria made the first ascent of Lhotse Shar. Lhotse Middle remained, for a long time, the highest unclimbed named point on Earth; on May 23, 2001, its first ascent was made by Eugeny Vinogradsky, Sergei Timofeev, Alexei Bolotov and Petr Kuznetsov of a Russian expedition.
On May 20, 2011, 17 year old Arjun Vajpai from India became the youngest person to climb Lhotse.
