Pumori Pre-Monsoon Attempts. A Japanese expedition reached 6400 meters on Pumori via the southeast face to the east ridge on March 28, but the climb was called off when leader Yoshikuni Mori fell into a crevasse and was killed. The deputy leader was Satoshi Kato. An expedition of four Japanese and two Frenchmen led by Isao Niizuma was also unsuccessful on the same route. They got to 6700 meters on May 8. Norwegians Per Gunnar Olsen, leader, Eirik Rosvoll and Roar Ljoen attempted the southwest ridge, but they reached a high point of only 6000 meters on April 5. Italians under the leadership of Stefano Agostini hoped to make the climb via the southeast spur to the Lingtren Col and the east ridge but had to give up at 6375 meters.
