Firehouse has the following report, "About 50 tourists and Havasupai Tribe members spent the night in a shelter after being rescued by helicopter from flash flooding that tore out of a gorge off the side of the Grand Canyon.
Some people who were believed to be in the side canyon along Supai Creek were unaccounted for after the flood struck during the weekend. No injuries had been reported.
Rescuers planned to evaluate weather conditions and the level of flooding Monday morning before deciding when they could safely resume air evacuations, said Grand Canyon National Park spokeswoman Maureen Oltrogge."
