North face of Mount Everest: routes and important points

The Norton Couloir or Great Couloir is a steep gorge high on the north face of Mount Everest in Tibet, which lies east of the pyramidal peak and extends to within 150 m below the summit.

Its companion to the west of the summit is the Hornbein Couloir.

Green line Normal route, largely corresponds to the 1924 Mallory Route, with high-altitude camps at about 7,700 and 8,300 m, today's 8,300 m camp is somewhat more to the west (2 triangles)

Origin of the name[edit]

The steep gorge was named after the lead member of the 1924 British expedition, Edward Felix Norton, who reached a height of about 8,570 metres (28,120 ft) in this steep valley during an unsuccessful summit attempt on 4 June 1924. He avoided the dangerous windswept ridge and, by traversing the north face, ascended into the gorge which has since borne his name.

Everest solo, Reinhold Messner[edit]

The Norton Couloir was the scene of one of the greatest mountaineering achievements when, in 1980, Reinhold Messner entered this gorge to avoid what, for a solo climber, was a dangerous ridge - especially to circumvent the Three Pinnacles - and ascended to the summit, alone and without using supplemental oxygen. The most successful climb to that point by F. Edward Norton in 1924, was Messner's inspiration for this attempt: Norton had also used no oxygen.

Other climbs through the couloir[edit]

In 1984 an Australia expedition succeeded in climbing a new route. From the main branch of the Rongbuk Glacier they went directly onto the north face and established their third high-altitude camp at the entrance of the couloir at 7,500 metres. From another camp at 8,150 m Tim Macartney-Snape and Greg Mortimer reached the summit on 2 October without bottled oxygen, the first Australians to reach the top of Everest.[1]

In 2001, young French snowboarder Marco Siffredi succeeded in the first snowboard descent of Everest by using the Norton Couloir. He died the following year attempting a new descent via the Hornbein Couloir.[2]
