Rescuers found the bodies of two men after a flash flood swept through the Grand Canyon on Saturday.

A third man remains missing.

Officials said about 80 other people were rescued over the weekend.

The flood badly damaged the park's only water pipeline.

Officials barred tourists from staying at lodges inside the park.

They also issued emergency water restrictions for year-round residents.

The flood hit the Bright Angel Creek area, which hosts 4.4 million visitors a year.

Incident Cmdr. Dave Black said searchers used night vision and other equipment.

By sunset Saturday, 45 people were rescued.

Another 37 were evacuated Sunday.

Rangers used the park's permit system and checked vehicle license plates to track missing people.

Black said there is no reason to believe anyone else is missing besides the one person unaccounted for.

The two dead men were identified as John Giusti, a Texas chiropractor, and Brent Rosenkranz, 42, a martial arts studio owner.

The missing man is Timothy Smith, 53, a Wyoming pilot.

The three men had ties to Granbury, Texas, and planned several days of hiking and camping together.

Their families said they last heard from them Thursday.
