| Route Notes | Pertemba summited twice Everest with Bonington SW Face 1975 Autumn; 3rd time with Norwegian; Khumjung, VDC 49 years. 2 Sherpas of second team used oxygen while sleeping but not while walking. All Japanese used oxygen while sleeping and walking. Made route. Then Basques and Slovakians followed. The other teams did not use oxygen. First summit group started of 5 am from C4 and reached C4 11:20 and slept C1 (reached C1 6:30 pm). Second group started at 5 am from C4 and reached C3 (they slept there) at 3 pm. Slovakians did not use oxygen; not enough acclimatization. Stayed in C4 one night instead of 2 nights like Japanese. Yamamoto will return Nov 17 or 18 (maybe for Annapurna); used C2 only once. |
