When I climb a fourteener, a 14,000-foot/4,260-meter peak, in the winter by myself, I leave an itinerary and information about where my vehicle will be parked and the name of the county sheriff to contact in case I don't get home.

I was able to first snap the radius and then within another few minutes snap the ulna at the wrist and from there, I had the knife out and applied the tourniquet and went to task. It was a process that took about an hour.

What you're looking at there is my arm, going into the rock... and there it is, stuck. It's been without circulation for twenty-four hours. It's pretty well gone.

I was accustomed to being in far, far riskier environments. So I thought going into that canyon was a walk in the park - there were no avalanches, it was a beautiful day and I was essentially just walking.

I'd fallen in love with a woman but she broke up with me and I was devastated. Six months later, I went into a suicidal depression from the break-up of the relationship, but I resolved to not do what my friends had done. And so I reached out for help

How would I behave in a situation that caused me to summon the essence of my character? The tragedy inspired me to test myself. I wanted to reveal to myself who I was: the kind of person who died, or the kind of person who overcame circumstances to help himself and others

I kind of entered a flow state. I've been there before while climbing. You are not thinking ahead. You are just thinking about what is in front of you each second.
