Authorities have come to the aid of a skier trapped on an icy slope alongside Mount Washington.

The New Hampshire Fish and Game Department said 20-year-old Sean Bagdon of Colchester, Vermont, had been skiing down Burt Ravine on the western side of the mountain Wednesday when he encountered icy conditions. Fearing a fall further into the ravine, he asked his skiing companion to call 911.

Rescuers used a snowmobile to ride up along the Cog Railway, then hiked up approximately a quarter mile before encountering Bagdon’s skiing companion, who had waited alongside the tracks to direct them to him.

A rescuer secured Bagdon with a safety harness and rope and guided him up and out of the ravine.
