Route Notes	Nissen reached C2 on 8 May. Gorgan and Roux also reached C2 same day. Sherpas started fixing the rope towards C3. Then thunderstorm started, sometimes it was complete white-out. He had to spend four nights in C2. He descended to C1 on 12 May in bad weather. The storm was very strong. He could not stand and had to crawl. On 13 May the weather was good, descended to ABC. There was not enough time for Nissen to go back to mountain. He returned to Kathmandu on 15 and will leave on 23 May. Fixed rope: Monterosa Sherpas put up until C2 (no idea how much).
Accidents	Jakobsen suffered from high altitude sickness
