Dhaulagiri I, Ascents and Tragedy. After completing his ascent of Annapurna I, Carlos Carsolio, a Mexican who has climbed eleven of the 8000-meter peaks, joined Norbert Joos’s predominantly Swiss team on May 11. On the 14th, he, Joos, and four of Joos’s team left Base Camp at 4800 meters for a push to the top. Joos’s group dropped out at various points along the standard Northeast Ridge route. Carsolio climbed all night and reach the summit at 10 a.m. on the 15th. Albrecht Hammann, a member of Joos’s team, summitted on May 19, but became fatally ill from high altitude sickness on the descent.
