Will Gadd ice climbs Niagara Falls
Extreme athlete Will Gadd ice climbs the first ever ascent of Niagara Falls in Niagara Falls, New York, Jan. 27, 2015.
The idea of ice climbing Niagara Falls took root in 2014 when the "polar vortex" froze large parts of the Falls. Working in collaboration with Red Bull the permit for the climb came through three days before the ascent after Gadd submitted a very exhaustive safety plan.
