(Brief) Climbing History of Cho Oyo
- First ascent in 1954 (Austrian).
- 1959: First women's Himalayan expedition to an 8,000m peak. (Two
of the women and one Sherpa were killed in two separate avalanches.)
- Approximately 450 people summited prior to spring, 1995.

person on top.

the safest of the 8,000m peaks).
