The common eastern face of Everest and Lhotse is called the Kangshung Face. Here, the Kangshung Glacier is fed and then becomes the Kama Chu river to flow through the Kama valley towards the east. South of the glacier and east of Lhotse lie the Pethangtse (6738 m), and the massif of the Makalu (8463 m) with its neighbouring peaks of Makalu II (7678 m − also called Kangshungtse) and Chomo Lonzo (7818 m), whose imposing north face hides the view of the main Makalu summit. The border between Nepal and China runs over this summit.
