Nine people died and a 13-year-old boy was still missing on Sunday after a furious flash flood tore through a group of family and friends cooling off in a creek in the Tonto National Forest in Arizona.

Gila County Sheriff's Detective David Hornung told The Associated Press that the group from the Phoenix and Flagstaff areas had met up for a day trip along the popular Cold Springs swimming hole near Payson in central Arizona and were playing in the water Saturday afternoon when muddy flood waters came roaring down the canyon.

The group had set out chairs to lounge on a warm summer day when miles upstream an intense thunderstorm dumped heavy rainfall on the mountain.

Search and rescue crews, including 40 people on foot and others in a helicopter, recovered the bodies of five children and four adults, some as far as two miles down the river. The victims ranged in age from a 60-year-old woman to a 2-year-old girl. Authorities did not identify them. Four others were rescued Saturday and taken to Banner hospital in nearby Payson for treatment for hypothermia.

Rescuers got to the four victims quickly after the crew heard their cries while they were nearby helping an injured hiker.
