Southeastern Utahs Corona Arch, a towering geological feature glorified last year on YouTube as the Worlds largest Rope Swing, has claimed the life of a 22-year-old thrill seeker. Kyle Lee Stocking died Sunday while trying to swing from the 140-foot-high arch, which has experienced a surge in popularity during the past year because of YouTube videos and sharing of videos on social media.
