The Hornbein Couloir is a narrow and steep couloir high to the west on the north face of Mount Everest in Tibet, that extends from about 8,000 to 8,500 m (26,200 to 27,900 ft) elevation, 350 metres (1,150 feet) below the summit.
For the first 400 m (1,300 ft) vertical, the couloir inclines at about 47°, and the last 100 m (330 ft) is narrower and steeper with about a 60° average incline. To the east on the north face with less angle is the much larger Norton Couloir.
