Surviving an avalanche Surviving an avalanche was no on Thomasslist of things to do seeker of epic propo on he had jumped from a helicopter to ski remote mountain slopes and traversed half of Antarctica his f doing in packs hadn't failed him on the day of his accident. 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. Thomas even had special equipment for this particular type of skiing His well worn pair oftraditional skis wouldn't be sufficient, so he'd expended an extra two hundred pounds on a wider set ofblades especially made for sking in powder And it wasn't as ifsafety was he last thing on hismind. He'd brought his avalanchekitincase of emergencies He wore an airbag that would help to keep him near the surface if he pulled the cord in time and another device which would assist him with breathing under snow The rescue services number was programmed into his mobile one, and his avalanche tra which emits an emergency signal was equipped ph with fully charged batteries. sin familiar territory. He had always skied with a trusted ski buddy, with never Thomas's run that day an incident to report. Perhaps he had been ed into a false sense of security In fact, he had intended to ski with a friend that morning When his friend couldn't make it, Thomas considered not going himself, but the snow on the mountain had fallen just the night before. and the lure was too intense. His run was a wide, bare track of slope nestled between two pine forests a real skier's delight, and quite popular with the locals as well They say an avalanche is like a sleeping giant, waiting to be woken up by even the slightest of nudges. Thomas gave this giant more than a nudge-he skied right and before he knew it, he was skiing on top of it as it slid down the mountain a with him. 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. He the dark solitude, even though he knew he might never be found. Luckily for him, the giant had caught the a on of others, and the transceiver was doing the iob it was designed to do.
