Cho Oyu, Autumn Ascents and Attempt. Cho Oyu is a very popular climb. It is ascended mostly by the west ridge and the west face, regardless of whether the climbers approach from the Nepalese or the Tibetan side. There were two successful Spanish ascents from Nepal in the post-monsoon season: a group of eight led by Pedro Tous, which put Pitxi Equillor, Patxi Fernández and Koldo Aranguren on the summit on October 6 and Tous and Mikel Reparaz on the 8th; and a party led by Josep Pujante, of which Pujante, Miguel-Angel Martínez, Josep Tapias and Ang Phurba Sherpa got to the top on October 6. Soviet Alexandr Glushkovsky, nine Soviets and a Bulgarian tried the southwest ridge but could get only to 7850 meters on November 14.
