(Arcteryx) (Newser) – Canadian champion climber Guy Lacelle died yesterday after an avalanche swept him off a mountain in Montana during a climbing competition. Lacelle, considered one of the world's leading ice climbers, was ascending a gully when the team above him triggered the avalanche, authorities say. His body was retrieved by a search and rescue team. Lacelle, 54, was "a fanatical ice climber" and his death is a "huge, huge loss," the director of a climbing equipment firm tells AP.
