Skier killed in British Columbia avalanche: report Fri Feb 22, 2013 9:13pm EST (Reuters) - At least one person has been killed in British Columbia after a group of back-country skiers was caught in an avalanche on Friday in an out-of-bounds area near a mountain ski resort, Canadian media reported. Canada's CTV news said on its website that the skier was in a group of five or six men skiing on the back side of the Revelstoke Mountain Resort, and that three of the men were caught in the slide. Rescue officials were near the scene, according to CBC News, which had earlier said that three to five people may have been buried by the avalanche. The Canadian Avalanche Center had upgraded the risk of slides to "high" in alpine and treeline mountain regions throughout most of British Columbia on Friday, CBC reported.
