Authorities in a US ski resort have praised rescue efforts to evacuate 140 skiers trapped on a ski lift due to a mechanical failure.
The incident happened during blizzard conditions at the Whitefish Mountain Resort in Montana.
It took more than two hours to rescue skiers, most of whom had to be lowered to the ground by winch and cables. None was injured.
An investigation is underway.
Here is a video of part of the rescue operation, taken by local resident Billy Marcial, which shows one person virtually abseiling down a rock-face.
