Route Notes When going for C2 winds so strong and temperature so cold, pitched camp at only 6750m and two days later on 20th, made their C3 at normal C2 site. All 3 members left C3 at 1:30 am NST; about 2:00 am Chin having problems: slurred speech, vision problem, so Viesturs went down with Chin while Gustafsson on up to top alone; Viesturs and Chin all way to BC at 3:30 pm and Gustafsson joined them there at 9:30 pm in moonlight. Viesturs and Gustafsson descended, brought down all gear. Chin improved quickly and descended and came down on own feet. Rope fixed as this: 40m in icefall between C1 and C2; above 6750m fixed 150m, in direct line up from there. Next to Annapurna I: Arrive BC 30 April by chopper; taking oxygen; probably only Viesturs and Gustafsson; plan to summit on 7 May 77. Return KTM 8-10 May by helicopter from BC. Stay Tibet Guest House or if successful, Yak and Yeti maybe.
