The Western Cwm. The Lhotse Face (centre right) is connected to Mount Everest (centre left) by the South Col (centre, lowest point on horizon).

Lhotse from Gorakshep

The western flank of Lhotse is known as the Lhotse Face. Any climber bound for the South Col on Everest must climb this 1,125 m (3,690 ft) wall of glacial blue ice. This face rises at 40 and 50-degree pitches with the occasional 80-degree bulges. High-altitude climbing Sherpas and the lead climbers will set fixed ropes up this wall of ice. Climbers and porters need to establish a good rhythm of foot placement and pulling themselves up the ropes using their jumars. Two rocky sections called the Yellow Band and the Geneva Spur interrupt the icy ascent on the upper part of the face.

On 19 May 2016, a high-altitude mountain worker, Ang Furba Sherpa, died when he slipped and fell down Lhotse face.[28]
