(KUTV) - Zion National Park announced it has closed several trails indefinitely.
Recent rockfalls and flash floods have caused substantial damage to the trails, which have made them unusable.
Angels Landing, Upper Emerald Pools and the Kayenta trail have been closed.
On July 11, rainfall produced the largest flood since 2011. This increased the flow volume of the river by nearly 200 times, according to Zion National Park.
As of now, the park warns visitors to not enter any narrow canyon when there is a chance of rain or a possibility of a flood.
Even low chances of rain have caused damage and dangerous conditions in the canyons.
When a flash flood warning is issued, all slot canyons and the Narrows are closed. Zion National Park warned visitors in a Facebook post to have a backup plan if they want to hike the Narrows.
