The North Col refers to the sharp-edged pass carved by glaciers in the ridge connecting Mount Everest and Changtse in Tibet. It forms the head of the East Rongbuk Glacier.
When climbers attempt to climb Everest via the North ridge, the first camp on the mountain itself is established on the North Col. From this point at approximately 7,020 metres above sea level, climbers ascend the North Ridge to reach a series of progressively higher camps along the North Face of Everest. Climbers make their final push to the summit from Camp VI at 8,230 metres altitude.The North Col was first climbed by George Mallory, Edward Oliver Wheeler, and Guy Bullock on 23 September 1921, during the British reconnaissance expedition.
