Cho Oyu Ascent and Shisha Pangma Attempt. Spaniards Bartolomé Quetglas and Ramon Alfredo arrived at the Cho Oyu Base Camp on September 5. They placed Camps I and II at 6400 and 6900 meters. On September 28, Quetglas climbed to the summit. Alfredo with porter Tirta Tamang established Camp III at 7500 meters and on the 29th headed toward the summit but this pair was driven back by high winds. Feeling well acclimatized, they moved to Shisha Panga, which they hoped to climb in only two days from the base. However, high winds prevented their completing the climb after they reached 7400 meters.
