Cho Oyu Northwest Face & Ridge (Normal Route)
The Northwest Ridge is the standard and most climbed route on Cho Oyu, approached from the Tibetan plateau via the Gyabrag Glacier. First climbed in 1954 by an Austrian expedition, the route features relatively moderate snow slopes of 30 to 40 degrees, punctuated by a single prominent technical crux known as the Ice Cliff at 6,700m.

Tactical & Camp Notes
While technically the most accessible 8,000m peak, extreme cold, altitude sickness, and disorienting summit whiteouts represent severe objective hazards on Cho Oyu.
Identified Objective Hazards
- •Treacherous hidden crevasses on the broad summit plateau during whiteouts
- •Extreme wind exposure sweeping unobstructed across the open Tibetan plateau
- •Acute mountain sickness from rapid elevation gains on gentle gradient slopes
- •Severe frostbite resulting from sub-zero temperatures dropping below -35°C
