First person to climb the ice at Niagara Falls

Recently released footage shows professional climber Will Gadd becoming the first person ever to to ascend frozen sections of the world's largest flowing waterfall, Niagara Falls. With 150,000 tons of water flowing over the crest every minute at speeds of nearly 70 miles per hour, the water impact is equivalent to roughly 4,000 eighteen-wheel trucks hitting the ground at the same time. The official climb distance is 140 feet and the route ran almost exactly along the United States and Canadian border. Over the past year, Gadd also climbed the rapidly melting ice glaciers of Kilimanjaro and won the prestigious Ouray Ice Festival climbing competition in Colorado.
