Event narrative (NOAA)
A Flash Flood on Phantom Creek killed two people and injured a third person. Runoff from the heavy rain associated with a thunderstorm several miles north of the flash flood site caught the three people as they were crossing Phantom Creek. All three attempted to save themselves by crouching behind a large boulder, but chest-deep water carried them downstream. The bodies of the two who were killed were found several weeks later, miles downstream in the Colorado River. The survivor was carried one quarter mile down Phantom Creek then another quarter mile down Bright Angel Creek before he was able to escape and hike out of the canyon.
