Hikers struggle to stay upright as a flash flood hits Zion National Park in Utah. One man tries to rescue a woman, but ends up falling into the raging river. Another tourist finds himself submerged in the wild waters as he tries to escape. The woman who shot the video said that she got out just in time. She was shocked at how quickly the water rose around her and other hikers. “All of this was not flooded just a few minutes ago,” she said.
