He had ventured out alone before, and in any case, most of the ski ranges around his mountain littered with forest rangers whose job was to help stranded hikers. So a solo trip by an experienced skier wasn't the most dangerous of adventures, Every seasoned skier is aware of both the risks and the joys involved with skiing off-piste It's a different experience from the snow that's been pa down into ice by the who have already crossed over it. Movements occur almost in slow motion as the skier glides in and out of powder. It's an exhausting challenge that requires effort from the skier's whole body, but a unique one that hooks a skier after just one run.

And if you ski on top of the giants mouth, it's likely to swallow you whole. As Thomas sank beneath powder, through his acute panic he managed t pull the cord on his airba The roar of the giant fell silent seconds later, and from beneath the snow it was as if morning had turned to night. Thomas tried to reach his phone, but his arm might as well have been cas concrete. Lying still his panic slowly shifting to an eerie peacefulness, he did his best to keep his chin up.
