(FLAGSTAFF, Ariz.) — Torrents of water rushed Thursday through an Arizona canyon famous for its towering blue-green waterfalls, sending tourists scrambling to benches, trees and caves as they sought higher ground. Rescue workers evacuated most of the 200 tourists after two rounds of flooding hit the Havasupai reservation, deep in a gorge off the Grand Canyon. All the tourists were accounted for and no one was seriously injured when heavy rain began falling Wednesday evening and before dawn Thursday, swelling a shallow creek that runs through a reservation campground, said tribal spokeswoman Abbie Fink. Tourist Benji Xie said people were swimming at the base of waterfalls when the flash flooding struck.
