The Lobuje Mountain consists of two different summits Lobuje East (6119m) and Lobuje West (6145m). Although they are connected by a continuous ridge there is a sharp gap and a considerable distance between them. The East Peak is recognized as a trekking peak, whereas the West is known as an Expedition Peak.
Lobuje is an attractive summit, offering a variety of existing routes and a wide scope for new lines. Seen from near Pheriche, the dark triangle of its rocky East Face rises above the moraines of the Khumbu Glacier to an icy skyline. This skyline forms the South Ridge, the junction of the East Face with the glaciated South-West Face and the line of the normal route of ascent. This in turn leads to the summit ridge running north-west from the top of East Face through several small summits to the East Peak.
The peak of Lobuje East is reached by descending a marked notch and climbing steep snowy slopes to the top. On most occasions, the mountain is climbed on the summit ridge only as far as a subsidiary snow summit, south–east of the true peak and before the notch. This peak is identified as the false peak. Laurence Nielson and Ang Gyalzen Sherpa made the first ascent to Lobuje East on 25 April 1984 although there are possibilities that others have reached the summit before. But no records are available.
