Devin Stratton accidentally skied off of a 150 unmarked cliff. His GoPro camera was filming the entire way down. He walked away without a bruise but his gear didn’t have the same luck. From the video description:
Turns out I am afraid of heights... Miraculously I didn't even have a bruise! I did break a lot of gear including my helmet. Thanks to Matt for helping me dig for nearly 5 hours I found my lost ski and skied down.
On the other hand some people ski off cliffs on purpose. Meet Jamie Pierre, who thought it was a good idea to drop off a 255 foot cliff to set a world record at Grand Targhee, Wyoming.
