Two climbers approaching Pinnacle Gully reported that they were swept down 70 to 100 meters from the start of the first ice pitch in Pinnacle Gully. In waist to chest deep snow the lead individual triggered the avalanche as he approached the ice from the north. The fracture occurred above the climber and was approximately 5 meters below the transition to steep ice. Neither climber was buried in the incident and no injuries were sustained.
