1The daredevil duo who was the first to scale a nearly frozen Niagara Falls
Niagara Falls, the collective term for the three waterfalls that dominate the border between New York State and Ontario, Canada, flows at a rate of up to two million liters per second. Because of that enormous volume, the falls almost never stop moving. In fact, other than a 30-hour dry spell on March 29, 1848, when an ice jam in the upper river blocked the regular flow of water, the Falls didn't come to a standstill until 2014 during an extreme wave of cold weather.
Even in those instances, the Falls never completely froze over, and any attempts to climb them is perilous. The water, albeit in smaller volumes, continues to flow, forming unstable layers of snow, slush, and ice. Still, for Gadd and Hueniken, being the first climbers to travel up Niagara Falls is a good way to go down in history. (Source)
2The aerialist who performed a record-breaking feat by hanging over Niagara Falls by her teeth
The stunt comes five years after her daredevil husband became the first person to walk across Niagara Falls on a high wire in 2012.
Wallenda was just high enough to avoid the mist and pesky wind currents that come with the Falls as she performed an elegant acrobatic routine, weaving in and out of a hula hoop. She dangled from her knees, her hands, her toes and, just like Nik did in 2011, only her teeth.

The approval came after nearly two years of lobbying governments in both the United States and Canada. Wallenda's walk also brought in $3.3 million of revenue to the city of Niagara Falls, New York. 38,000 people gathered in that state to watch the action.

5The first person to conquer the Horseshoe Falls in a barrel
The Pan American Exposition was taking place in Buffalo, New York, and Taylor felt she would be able to attract a huge crowd. A small boat towed the barrel containing Taylor and her cat into the main stream of the Niagara River where it was cut loose.
At approximately 4:30 p.m., the barrel was seen edging over the brink, only to reappear less than a minute later floating at the base of the Falls. Fifteen minutes later, the barrel appeared close to the Canadian shore, where it was dragged to a rock and its lid removed.
To everyone's amazement, Annie Taylor emerged from her barrel, dazed but triumphant. Her only injury was a cut on her forehead that she received while being extracted from her barrel. (Source)
6The man who set the record for being the first person to take the plunge down the Falls with no protection and later died repeating the stunt
Kirk Jones tried the stunt again on 2017—this time in a 10-foot inflatable ball—but was killed the second time around. The 53-year-old's body was recovered 12 miles away at the mouth of Lake Ontario, and his ball was picked up by the Maid of the Mist tour boat.
Jones survived the Falls on Oct. 20, 2003, when he went over wearing only his clothes. The man's family said Jones had planned his unprotected plunge as a daredevil stunt, but he initially said he was trying to kill himself. He broke his ribs and bruised his spine in the 180-foot fall and Canadian authorities banned him for life after he pleaded guilty to unlawfully performing a stunt and mischief. He was fined nearly $3,000. (Source)
7The daredevil who plunged to death while riding jet ski over Niagara Falls
Overacker planned to jet ski over the Falls on the Canadian side, deploy a parachute, and land safely. Strapped to his back was a specially designed parachute with thrusters. These thrusters were supposed to deploy before the chute to ensure that he was far enough away from the falling jet ski. Somewhere along the line, however, there was a malfunction. The parachute did not open, and Overacker fell to his death. His body was found by the Maid of the Mist, a Niagara Falls tour boat. Crew members brought him on board and tried to resuscitate him, but it was already too late. (Source)
