There's not much that needs to be said about the 200m high Helmcken Falls other than this: it is currently the hardest mixed-route ice and rock climb in the known world.

The fourth-highest waterfall in Canada is backdropped by a massive, upside-down amphitheatre of overhanging rock. Spray from the waterfalls hit the wall, covering it in a thick (and sometimes thin) layer of ice. But despite freezing ice spray from the waterfall, British climber Tim Emmett, and Klemen Premrl, from Slovenia, conquered the notorious ice climb through a new route, Interstellar Spice.
