When ascending the Khumbu valley at the start of the successful 1953 Everest expedition, John Hunt said that the glacier appeared as if it could only originate at an apparent valley head between Lingtren and Nuptse - the Icefall and Western Cwm were completely invisible around the sharp bend in the glacier. He described one summit of Lingtren as being square and steep-ridged and another to the east (he called it Lingtren Two) as thin as a wafer at its top, looking incredibly fragile.
