NIAGARA FALLS-- A CH-47 Chinook assigned to the New York Army National Guards Bravo Company 3rd Battalion 126th Aviation removes a 3900-pound steel pontoon from the Niagara River just above the American side of Niagara Falls in Niagara Falls New York on May 4 2022. The pontoon which washed away from an ice dam in 2019 was removed because of concerns that it could go over the falls and damage the Cave of the Winds.
