Uli Biaho, Attempt and Near Disaster. A Spanish Catalan expedition led by Oscar Cadiach and composed of Enric Dalmau, Joan Carles Grisso and Lluis Rafols was swept down several hundred meters by an avalanche in the middle of the night as they were camped high up in an attempt to climb Uli Biaho. Though they suffered some injuries, they were able to descend, but they gave up the expedition.
