Lhotse stands at 8516 M, making it the 4th highest mountain in the world. It is situated at the border of Tibet and Nepal. Its long east-west crest is located immediately south of Mount Everest, and the South Col, a vertical ridge that never drops below 8,000m, connects the summits of the two mountains. Lhotse has three summits: Lhotse Main 8,516m, Lhotse Shar 8,383m and Lhotse Middle or East 8,413m.
Sometimes mistakenly, Lhotse has been identified as the south peak of the Everest massif. However, no serious attention was given to climbing Lhotse until Everest had finally ascended. Lhotse was first climbed in 1956 as an alternative route toward the summit of Everest.
Ernst Reiss and Fritz Luchsinger, who were part of a Swiss expedition, first climbed Main Lhotse in 1956. Then, Sepp Mayerl and Rolf Walter climbed Lhotse Shar on December 5, 1979, by taking the SE ridge.
A deep scar, an icy gully known as the Lhotse Couloir, marks The West Face of Lhotse; the couloir is the crucial test for the Lhotse climb, mainly because the climbing conditions of the couloir are affected by weather and seasonal snowfall.
The route progresses through Khumbu icefall. Moving further, we will reach Camp 1, at the top of Khumbu icefall, surrounded by crevasses. From Camp 1, we will pass through the lateral moraine to the west ridge that greets us with a close-up view of Lhotse. This place is perfect for Camp 2. Leaving Camp 2, we will reach the Lhotse wall by crossing glaciers and ice cliffs, where we will set Camp 3. Camp 4 is located near South Col. From Camp 4. We will proceed through steep rock sections to the summit.
