I've tried my hand at ice climbing a few times before (on East Vail's frozen waterfalls and Rainier's Emmons Glacier, most notably), and On The Edge's Candace Horgan practically has ice tools for hands.
That said, Will Gadd has us way beat: Tired of "regular" ice climbs, the Crazy Canuck took to climbing icebergs floating off the coast of Labrador. That sounds nuts enough, but consider the fact these brittle hulks regularly shatter completely, sending their occupants into a hypothermic ocean. I'd say that throws Gadd into a whole new realm of wackypants.
Thank God he filmed it (above): That's just an excerpt -- look out for the rest of Aweburg to hit adventure film fests later this year.
