There are two distinct summits to lobuche Peak - lobuche East (6,119m/20,070ft) and lobuche West (6,145m/20,161ft). Although a continuous ridge connects them there is a sharp gap and a considerable distance between them. lobuche 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 northwest from the top of East Face through several small summits to the East Peak. lobuche East: The true East Peak is quite striking and is reached by descending into marked notch and climbing steep snow/ice slopes to the top. This is rarely climbed and is often mistaken for lobuche West. Most attempts on the mountain climb the summit ridge only as far as subsidiary snow summit, before the notch, southeast of the true peak. Numerous parties have attained the false summits east of the notch, but the first recorded ascent of the true lobuche East seems to have been made by Laurence Nielson and Sherpa Ang Gyalzen on 25th April 1984.
