Russian daredevil Valery Rozov has made a record-breaking base jump in a region even colder than his homeland. Rozov and his team endured temperatures below -22F to scale Antarctica's 9,613-foot Ulvetanna mountain, the Telegraph reports. He then leaped from the peak wearing a wing suit and flew for 45 seconds down a sheer face of rock before opening his parachute and landing. Following the stunt, the highest base jump ever attempted in Antarctica, Rozov and his team scaled two nearby peaks while waiting for their transport plane.
