Will Gadd and Sarah Hueniken, Canadian ice climbers, have become the first in the world to complete historic ascent of frozen Niagara Falls, parts of which have frozen over winter. They climbed about 45 metres up on the Horseshoe section of the famous falls, which borders the US and Canada.
In his interview (watch below), Gadd described how spray from the part of the waterfall that had not frozen made his ice climb slippery 🙂
