Advanced skiers like Norm Follett hope to communicate their message of prevention for anyone getting on the slopes in the wet and cold conditions.

“There’s a lot of guys a lot of really good skiers really appreciate solitude or have opportunity to go out by themselves for a couple hours—that’s the time when you have to invest in additional gear,” he said.

“For most of us who ski, part of the thrill is going out there with the minimum that you need,” said Karen Seaward.

“Four days is a long time no matter what and in these conditions it’s hard to imagine the person is wet and cold and then it’s usually hypothermia pretty soon,” she said.
