A rockfall, mainly consisting of sand and small rocks, came down on Hidden Canyon Trail late Friday afternoon, Zion National Park officials said in a news release on Facebook.
No one was injured, the news release said. Two similar rockfalls occurred in the same area on July 2 and July 4, covering approximately 45 feet of trail in one-and-a-half feet of sand.
Hidden Canyon Trail will remain closed until a hazard geologist examines the situation and the trail can be safely cleared.
Angels Landing, Kayenta Trail, Upper Emerald Pools Trail, West Rim Trail from the Grotto trailhead to Cabin Spring, and the terminus of Lower Emerald Pools Trail also remain closed due to major rockfalls that occurred on July 11. Park staff and engineers continue to identify strategies to fix or re-route the trails safely, the news release said.
It is not advised to enter any narrow canyon when there is a chance of rain or a possibility of a flood, officials said.
Weeping Rock, East Rim Trail, Observation Point Trail, Cable Mountain Trail and Deer Trap are still open.
