Cholatse

Cholatse (also known as Jobo Lhaptshan) (चोलात्से) is a mountain in the Khumbu region of the Nepalese Himalaya. Cholatse is connected to Taboche (6,501m) by a long ridge. The Chola glacier descends off the east face. The north and east faces of Cholatse can be seen from Dughla, on the trail to Mount Everest base camp.

There is a lake just below this pass to the east, and in Tibetan 'cho' is lake, 'la' is pass, and 'tse' is peak so Cholatse means literally "lake pass peak". Cholatse was first climbed via the southwest ridge on April 22, 1982, by Vern Clevenger, Galen Rowell, John Roskelley, Bill O'Connor and Peter Hackett. The north face was successfully scaled in 1984.
