Back in 2010, Teton Gravity Research were filming a new segment with Callum Pettit when he decided to drop in on a seemingly innocent looking run.
At the bottom of the run was a crevasse in the shape of a single hole. Callum knew he had to miss it and was confident he could do so.
However, he didn’t factor in the possibility that he could fall down the mountain, which he did. He tumbled and tumbled then ended up falling down the hole and into a crevasse.
How deep was it though? Take a look for yourself.
