Route Notes	BC near lake Yuligolja C1 near point 5661m C2 on SW Ridge. Reached ridge beyond C1 and found Japanese ropes which showed the way along easy rocks. Could have used these ropes "but not necessary, too easy there." From C2 followed left side of ridge to summit. Ridge 55-degrees steepness and climbed this steep part from C2 to top in 6 hrs without loads and without fixing ropes. Fixed no ropes during entire climb. Had strong cold wind on summit day. Left BC 11th Nov and took 4 days (had taken 7-1/2 days from Jiri to BC). Porters said they knew the way but did not and time spent finding correct way (should taken 6-7 days).
