Severe thunderstorms in Utah on Friday night left 20 people stranded in a popular canyon due to flash flooding, prompting a six-hour rescue mission.
According to a Facebook post by Grand County Sheriff's Search and Rescue, the agency initially responded to a call for three people who had been trapped by rising waters in Grandstaff Canyon near Moab. Rescue crews hiked up the canyon until they were stopped by water and were able to establish voice contact with the group.
