Route Notes	Four members of women's team and four Sherpas left C4 at 1 am on 31 May in snowfall which stopped at about 4 am below the summit. The team got to the top at 5:00 am. They stayed on summit for about 5 minutes, it was windy. While descending about 30 minutes, the fresh snow below summit broke which swept all climbers about 125 meters down. Tendi, the climbing guide said that all were in a panic. Fortunately, nobody was hurt and it took them about an hour to regroup and they safely went down to C2 around 5 pm and spent the night there. Next day all descended to BC. Sherpas: Tendi Sherpa, Tapting-6, 1954 (26 yrs in 19/7/1980 (2037/44/4)), Cho Oyu 2006 Dorje Sherpa, 22/6/1970 (8/3/2027), Dimbil, Tapting-9, Solu, Lhotse X1, Makalu X1,Cho Oyu X1 Nurbu Tshering Lama, 29/5/1983 (15/2/2040), Samti Bhandar-3, Ramechap Ngima Dorje Tamang, Gorakhani-7, Solu, 3/12/1973 (18/8/2030)
