Route Notes	BC at usual camp site ABC at east side of the ridge (deposit load) C1 on the ridge C2 before Grey Tower (traditional camp site). Normal climbing. Did not use their own ropes as there were already many ropes fixed. Reached summit all together at 1:15 pm stayed about 45 minutes. Mountain condition was snow/ice, perfect, excellent weather. Campsites were clean considering the number of expeditions. Climbing duration was reduced as they did not have to work on mountain much. Wedberg left BC on 25 as he has to attend some business. The team returned to Kathmandu on Nov 4. KTM departure Nov 8.
