Cho Oyu

Cho Oyu's height was originally measured at and at the time of the first ascent it was considered the 7th highest mountain on earth, after Dhaulagiri at (Manaslu, now , was also estimated lower at ). one remarkably similar to the used by Edmund Hillary in his 1955 book High Adventure. ==Climbing history==

Cho Oyu was first attempted in 1952 by an expedition organised and financed by the Joint Himalayan Committee of Great Britain as preparation for an attempt on Mount Everest the following year. The expedition was led by Eric Shipton and included Edmund Hillary, Tom Bourdillon and George Lowe. A foray by Hillary and Lowe was stopped due to technical difficulties and avalanche danger at an ice cliff above and a report of Chinese troops a short distance across the border influenced Shipton to retreat from the mountain rather than continue to attempt to summit. The mountain was first climbed on October 19, 1954, via the north-west ridge by Herbert Tichy, and Sherpa Pasang Dawa Lama of an Austrian expedition. Cho Oyu is considered the easiest eight-thousander, with the lowest death-summit ratio (th of Annapurna's). It is the second most climbed eight-thousander after Everest (whose height makes it the most popular), and has over four times the ascents of the third most popular eight-thousander, Gasherbrum II. It is marketed as a "trekking peak", achievable for climbers with high fitness, but low mountaineering experience. It has a broadly flat summit plateau with no cairn (the traditional prayer flags on Cho Oyu's summit plateau do not mark the "technical" summit), which can be a source of confusion, and debate, amongst climbers (see Elizabeth Hawley). ==View==
