Five snowboarders were killed Saturday when they were swept away in an avalanche in the Rocky mountains near the western city of Denver, local officials said.
In the early afternoon a group of six snowboarders ventured into a backcountry skiing area known as Loveland Pass, some 100 kilometers (60 miles) west of Denver outside the boundaries of the Loveland Ski Area, where they were struck by a wall of snow.
"I can confirm that five snowboarders have been found dead at Loveland Pass," an official at the Clear Creek County's sheriff's office told AFP.
The sixth snowboarder was rescued after calling for help.
The site of the accident is some 3,600 meters above sea level.
Another snowboarder was killed Thursday in an avalanche in the same region.
The Colorado Avalanche Information Center warned Saturday that there was a considerable risk of an avalanche in the area the snowboarders visited, urging extreme caution.
