Hundreds of tourists, along with members of the Havasupai Native American tribe, were rescued from the Grand Canyon today after a dam broke causing serious flooding. About 300 people were rescued by helicopter over a 10-hour period after the Redlands Dam, south of the village of Supai, and 220 miles northwest of Phoenix, was breached, the Arizona Republic reports.
A river near the village swelled by as much as 8 feet. "We've had two days of very heavy rains from thunderstorms [that] dropped significant moisture over that area," said a forecaster with the National Weather Service in Flagstaff. "That's what caused the dam to become overtopped and breached."
