Waugh, Andrew (1810-1878):

Andrew Waugh was a surveyor who helped map India and large areas of central Asia. He became the Surveyor-General of the British India Survey in 1843 after George Everest retired. Waugh and his team measured Peak XV now known as Mount Everest, recording a height of 8,840 metres (29,002 feet). Waugh later suggested that Peak XV be named after Sir George Everest.

Western Cwm:

The Western Cwm lies to the west of Mount Everest linking the Khumbu Icefall with the southern base of the summit. It rises from 5,791 metres (19,000 feet) to 6,706 metres (22,000 feet). This is one of the most popular routes used by climbers to reach the summit. This method was chosen by the 1953 Everest Expedition. The Western Cwm takes the form of a large bowl, enclosed by the peaks of Lhotse and Nuptse to the south and the Western Ridge to the north.
