Flash FloodingFlash flooding occurs from time to time in the canyon. In 2008 a powerful flash flood carved out two new waterfalls and left an old one completely dry. Flash floods happen some summers during the monsoon season - July through September.
Warning systems are in place and during the last flood, all visitors were safely evacuated. Before the flood arrived, all campers were advised during the night to move to higher ground - this action was taken by the rangers in coordination with the tribe to ensure everyone's safety.
