Authorities have recovered the bodies of five snowboarders who were killed in a backcountry avalanche on Colorado’s Loveland Pass.

Clear Creek County Sheriff Don Krueger said multiple search and rescue crews located the bodies Saturday. A sixth snowboarder was caught in the slide. That person’s condition was unknown.

Krueger said authorities are pretty certain the snowboarders triggered the avalanche, which he said was about 600 yards wide and eight feet deep.
