Will Gadd, Canmore Adventurer, Is First Person To Climb Niagara Falls (VIDEO)

People have survived going over Niagara Falls, but an Alberta man has become the first to make the ascent up them.

Will Gadd, a (very brave) adventurer from Canmore, became the first person to climb a wall of spray ice at the edge of Niagara's Horseshoe Falls.

Gadd, 47, was followed up the falls on Jan. 27 by climbing companion Sarah Hueniken, 34.

"The power of the falls is staggering," Gadd told National Geographic. "It vibrates your intestines and makes you feel very, very small. I've never experienced anything like it."

According to the magazine, Gadd and Hueniken made the 150-foot ascent along a 30-foot-wide strip of rotten spray ice that formed along the left edge of Horseshoe Falls — the most powerful waterfall in the world.

Gadd told the climb would not have been possible if not for this year's cold winter.

"I checked out the spot we were thinking of climbing in the summer," says Gadd. "You'd be swept away by the torrential downpour then."

"On a warm winter, there's no climb here."

Gadd, considered one of the world's best ice climbers, was named one of National Geographic's 2015 "Adventurers of the Year."

Last year, he scaled B.C.'s Helmcken Falls, a 141-metre ice and rock climb that is considered one of the most difficult in the world.

He also took a 35-day trip from B.C.'s Robson Valley to the United States border — not by road, but by paragliding mountain to mountain.
