The surging waters in Utah's Zion National Park were captured on video and posted to social media after the July 29 rescue.
A terrified boy clung to an adult as a steady hand guidedboth to safety in the video as they went across ankle deep rushing water which quickly rose to their knees.
The human chain was made up of about a dozen hikers, most of them relatives. Jarrod Finkenthal was one of the people who helped.
“It was really cool seeing my nephew and brothers, everyone lined up together, and helping them,” he said. “We all noticed that they were struggling at the same time and we all went in at the same time. We all helped out as best as we could.”
