Cho Oyu (or Qowowuyag; in Nepal ????, Tibetan in Wylie transliteration: jo bo dbu yag; Chinese: ????, Pinyin: Zhuó'àoyou Shan) is the sixth highest mountain in the world. Cho Oyu lies in the Himalayas and is 20 km west of Mount Everest, at the border between China and Nepal. Cho Oyu means "Turquoise Goddess" in Tibetan.
Cho Oyu was first attempted in 1952 by an expedition led by Eric Shipton and including Tom Bourdillon, but technical difficulties at an ice cliff above 6,650m (21,820ft) proved beyond their abilities. (Today, these ice cliffs are normally ascended using fixed ropes.) Cho Oyu was first climbed on October 19, 1954 via the northwest ridge by Herbert Tichy, Joseph Jöchler and Sherpa Pasang Dawa Lama of an Austrian expedition. Cho Oyu was the fifth 8000 metre peak to be climbed, after Annapurna in June 1950, Mount Everest in May 1953, Nanga Parbat in July 1953 and K2 in July 1954.
Just a few kilometres west of Cho Oyu is Nangpa La (5,716m/18,753ft), a glaciated pass that serves as the main trading route between the Tibetans and the Khumbu's Sherpas. Due to its proximity to this pass and the generally moderate slopes of the standard northwest ridge route, climbers consider Cho Oyu to be the easiest 8,000 metre peak to climb, and it is a popular objective for professionally guided parties.
