In August 2015, Spencer Seabrooke broke a slacklining world record by making his way across a 305-metre deep gully at the Stawamus Chief in Squamish, British Columbia

It was a “free solo” walk, meaning Seabrooke wasn’t wearing safety ropes of any kind.

A drone video, shot by Whistler videographer Zachary Moxley, shows the daredevil stumbling not once, but twice during the pass, before clutching the rope for dear life.

“Without a doubt, it’s the fear of falling that keeps you alive,” Seabrooke told The Huffington Post B.C. in an interview.

“There’s no lines at all, so if I hadn’t caught the line in those moments, I would’ve been mashed potatoes after a seven-second free fall.”
