One man is dead after he was buried by an avalanche on a western Canadian mountain, bringing to 19 the number of snowmobilers who have died in Canadian slides this winter, AP reported. Royal Canadian Mounted Police spokesman Constable Rob Roffel said Saturday that a number of snowmobilers were taking turns riding up British Columbia's Monashee Mountains, near Valemount, when the 24-year-old man triggered the avalanche. Roffel says the man was buried near the bottom of the hill. Other snowmobilers were able to locate and dig him out, but efforts to revive him were unsuccessful.
