Four experienced backcountry snowboarders and a skier who died in an avalanche north of Loveland Pass on April 20 were buried four hours before a rescue was attempted, according to an investigation by the Colorado Avalanche Information Center.
Officials originally estimated that the avalanche happened at 1 p.m., and rescuers arrived at 2 p.m. However, the avalanche actually occurred about 10:30 a.m.
