Two people snowshoeing in the mountains of Colorado were killed in an avalanche over the weekend, authorities said, writes ABC NEWS.

Their bodies and the body of their dog were found buried near Hoosier Pass in central Colorado by searchers using an avalanche rescue dog, the Colorado Avalanche Information Center said Sunday. Summit County Coroner Regan Wood identified the victims Monday as Hannah Nash, 25, and Drake Oversen, 35, both of Colorado Springs.

The cause of death was listed as blunt force trauma and asphyxiation.

The search started after Nash and Oversen did not to return from an outing on Saturday. Using information about their plans from family and friends, searchers found a recent avalanche and a faint track on a flank of North Star Mountain before the dog located the bodies, the avalanche center said in its preliminary report on the slide.

The avalanche was the second fatal slide this winter in Colorado.
