The Northwest Ridge:
Also known as the Tichy Route, the Northwest Ridge was the route of first
ascent and is the route we will climb. It begins from the Gyabrag Glacier at
the base of Peak 6446. Advanced base camp (ABC) will be located here, at about
5500 m (18,000') depending on snow levels. The route is predominately 35 to 50
degree snow and ice with a few short bands of rock and vertical ice sections.
The route ascends the scree and firn of Peak 6446, skirting the summit of Peak
6446 on its western side. Camp 1 will be put in at about 6400 m (21,000'),
where Peak 6446 joins the Northwest ridge proper of Cho Oyu. From Camp 1 the
route follows the Northwest ridge, and then opens out onto the Northwest face
of the upper mountain. About halfway between Camp 1 and Camp 2 the ice cliff
is encountered, which is a 150 foot mix of short bands of near vertical ice.
Most of the route between Camp 1 and 2 will be fixed with rope. Camp 2 will be
located at about 7000 m (23,000'). Some expeditions have put in a temporary
intermediate camp between C1 and C2, below the ice cliff on the Northwest
ridge at about 6600 m (21,600'), especially during the first or second
High camp will be placed at about 7450 m (24,500') to maximize the chance of
success on summit day. From here, the first obstacle is the "Yellow Band"
(same as on Everest) which is usually fixed with rope, and which requires some
strenuous climbing. Above this, more rocky bands and steep snow put the
climbers on the summit ridge snowfield. Expeditions usually continue up this
steep snowfield to the crest of the Northwest Ridge and the false summit.
From here climbers cross a broad plateau, with a very small rise to the true
summit of 8201 m (26, 901 feet). From the true summit it is possible to get
an incredible view of Everest.
