About 200 tourists were being evacuated Thursday from a campground on tribal land near famous waterfalls deep in a gorge off the Grand Canyon.
The evacuations came after the Havasupai Tribe reservation was hit with two rounds of flooding Wednesday and early Thursday, officials said.
An emergency response team was moving tourists from the campground below the tribal village to a school.
All the tourists have been accounted for and no one was seriously injured, tribal spokeswoman Abbie Fink said.
Posts on social media showed water roaring through a canyon and people saying the area was a mess.
People slept in a community building and will be helicoptered out Thursday. The tribe also provided food and supplies.
The reservation is known for its blue-green waterfalls. Spots in the campgrounds sell out quickly every year.
Fink says the reservation will be closed to visitors for more than a week as damage is accessed.
