More than 250 residents and tourists have evacuated an American Indian village in a remote, scenic offshoot of the Grand Canyon after weekend flooding that wrecked trails and nearly washed away some river rafters in the rugged gorge. Helicopters on Aug. 18, 2008, ferried 85 people out of the Havasupai tribal village of Supai, about 2,300 feet below the canyon rim, said Gerry Blair, a spokesman for the Coconino County Sheriff's Department.
