A video of two extreme athletes completing a dangerous ice climb on Helmcken Falls in British Columbia has gone viral online.

Adventurer Tim Emmett and his friend Klemen Premrl successfully completed a route called the Wolverine, which is considered the most challenging climb in the world.

Just-released video of the pair climbing and dangling upside down from the frozen waterfall has garnered approximately 60,000 views in a week on Vimeo.

Emmett and Premrl wanted to be the first to conquer the route and made the climb in 2012.

“It’s the most impressive, natural place I’ve ever seen, and I’ve been to a lot of different places,” Emmett said.

The British daredevil is well-known for his extreme stunts and scrambling up the sides of mountains. He raced a car on the BBC’s “Top Gear” program.

Few have seen anything like the Wolverine in the ice climbing world, Emmett said.

“Normally when you go ice climbing, water falls vertically,” he said. “Think about this: it’s made out of spray ice, it can form on really overhanging cave walls.”

The pair essentially climbed an ice-covered cliff equivalent to the height of a 70-storey building -- much of it at a 45-degree angle.

The feat didn’t come without several failed attempts. But with fatigue setting in and ice forming on their clothing, Emmett and Premrl persevered, eventually completing the climb.

Emmett showed off the video at the kick-off to the Vancouver International Mountain Film Festival on Friday, and uses it at public appearances to promote outdoor activities and a message of living life to the fullest.

The Brit plans to climb Helmcken Falls again but wants to base jump his way down next time.
