Video: Ice Climbing Helmcken Falls in Canada

At 140 meters (459 feet) in height, Helmcken Falls is the fourth tallest waterfall in Canada. During the winter, it doesn't freeze solid, but it creates enough of a spray to freeze the cliffs that surround it. In this video, we follow climber Klemen Premrl as he attempts to go up the ice walls along a route known as "Interstellar Spice." Along the way, he'll find out why this is considered one of the toughest mixed routes in the entire world.
