The bodies of five snowboarders were found Saturday in Colorado's White River National Forest.
The snowboarders were trapped by an avalanche on a high mountain pass at an elevation of 11,990 feet, according to officials.
A sixth member of the backcountry snowboarder group was able to escape the snow. Sheriff Don Kruge said the man survived by digging himself out and then hiked until he was able to flag workers with the Colorado Department of Transportation.
The snowboarders' names weren't immediately released. All of the snowboarders were wearing avalanche beacons and proper equipment, according to the sheriff's office.
The Colorado Alpine Rescue Team said it was the state's deadliest avalanche-related accident since 1962.
