Rescue crews had to evacuate nine hikers by helicopter Tuesday after a rockfall forced Zion National Park to close its Hidden Canyon trail.
The rockfall marked the third time since the start of July that the park has had to close the trail, which winds between red rock cliff sides just a few miles from the park's main roadway.
A park statement said that none of the nine was injured.
The trail will be closed for at least a week while staff checks the area for more potential rock falls.
Weeping Rock, East Rim Trail, Observation Point Trail, Cable Mountain Trail and Deer Trap are still open.
