11 visitors trapped as dangerous flash flooding tears through iconic national park

While none of the hikers was swept away, conditions left the groups unable to continue safely, the outlet reported.

About 15 to 20 members of the county's search and rescue team, emergency medical services and the National Park Service responded to help the stranded visitors.

The rescuers had to wait for conditions to improve in order to move people out safely.  

The rescuers then helped the groups make their way out of the affected areas, according to FOX 13.

Following medical evaluations, two hikers showed signs of hypothermia and were taken to a hospital. 

The other nine were released, the outlet reported.

The incident came during the Southwest's monsoon season, a period Bryce Canyon officials had warned visitors about earlier this month.

"Weather in the park can shift quickly," the National Park Service warned in the news release, urging visitors to remain aware of conditions both where they are and upstream.

"We want to help visitors enjoy their experience and take home memories that last a lifetime," Bryce Canyon National Park Superintendent Allana Olbrich said in the news release.

"We also want to help them do so safely, and having good information and awareness of the conditions they may encounter in these natural environments can make all the difference in creating those lasting memories," Olbrich added.

Fox News Digital reached out to Bryce Canyon National Park and the Garfield's County Sheriff's Office for further comment and details.
