| Route Notes | Needed fixed rope to 6700m for descent but had not enough rope. 17 Dec Dobashi, Okada and Yoshida in alpine-style attempt reached about 6600m but too far from there to summit for that day and gave up climb. 3 men had made route from C1 and now very tired, very windy and food supplies running out since had planned summit for 14-15 Dec. 18 Dec route to C1 and 19 Dec to BC. Would have taken 3 whole days to go to C2 to top to C2. Snow conditions very bad, like sugar. C1 to C2 snow mushrooms, BC to C1 easy. Saito went to C2 once while Uchiyama and Kawaguchi to C1 only. 1 member went to C2 once while 2 members to C1 only. |
