The North Col (Chinese: 北坳; pinyin: Běi Ào; Tibetan: Chang La) refers to the sharp-edged pass carved by glaciers in the ridge connecting Mount Everest and Changtse in Tibet.

Climbers make their final push to the summit from Camp VI at 8,230 metres (27,001 ft) altitude.

[1] The North Col was first climbed by George Mallory, Edward Oliver Wheeler, and Guy Bullock on 24 September 1921, during the British reconnaissance expedition.

Although long credited to Mallory, discovery of the North Col was in fact made by Wheeler about a week before Mallory confirmed its existence while searching for possible routes to the summit of Mount Everest.

In 1951, two mountaineers on the 1952 British Cho Oyu expedition, Edmund Hillary and George Lowe, crossed the Nup La Col, and "like a couple of naughty schoolboys" went deep into Chinese territory, down to Rongbuk and round to the old prewar Camp III beneath the North Col.[3] This map is inverted; south is up and north is down.
