AFter reading the article I thought he was not very well prepared.
He didn't seem to know how to find his way back to his "track" on his GPS device and he was wearing Levis. If he was in snow then why could he not follow his own tracks back the way he came? I doubt he had the ten essentials as it would apply to hiking in the winter alone in those conditions. I'm glad he survived, but I bet he would do things differently if there is a next time.

If you are traveling in difficult conditions in winter by yourself take a sleeping bag and a tent or at minimum, very warm clothing and an emergency bivvy bag. Since my friend died while climbing alone my wife won't let me go out by myself any more...and I agree.
