"A canyon renown for its narrow, twisting limestone walls became a trap for 12 hikers on Tuesday when a flash flood filled it with a wall of water 11 feet high. The guide for several of the hikers survived, battered and his clothes ripped off by the force of the water, and the body of one woman was found yesterday. The other 10 are missing and presumed dead. The storm came without warning. A cloudburst 15 miles away sent heavy runoff down a normally dry wash in Antelope Canyon toward the unsuspecting sightseers. Rain had not fallen where they were hiking, said Benson Nez, a ranger on the Navajo reservation which the canyon runs through."
