NPS Seeks Public Help Locating More Than 20 People After Grand Canyon Flash Flood

# What happened On August 29 a flash flood moved through Bright Angel Canyon in Grand Canyon National Park. The flooding affected sections of backcountry that connect popular trails, Phantom Ranch, Bright Angel Campground and Cottonwood Campground. Narrow canyon corridors such as the Box channel floodwaters quickly, creating hazardous and rapidly changing conditions.

# Who's missing and where officials are focused Park officials say more than 20 people may still be missing or unaccounted for after the flood. The request for public help targets anyone who was in the Bright Angel Creek corridor on August 29. Specific areas of concern include:

• Box (a narrow section north of Phantom Ranch)
• The stretch of the North Kaibab Trail between the North Kaibab Trailhead and Phantom Ranch
• Bright Angel Campground and Cottonwood Campground

These are high-traffic backcountry routes that connect trailheads, Phantom Ranch, and campgrounds.

# What information the NPS needs

• Person's name and approximate location during the flood
• Planned travel route and group size
• Clothing and backpack descriptions
• When the person was last known to be in the area

You do not have to identify yourself when providing information.

# How to report a tip Contact the NPS Investigative Services Branch by phone or email:

• Tip line: 888-653-0009
• Email: nps_isb@nps.gov

Provide as many of the requested details as you can. Even small pieces of information may help rangers and search teams narrow their efforts.

# Why flash floods are dangerous in the Grand Canyon Heavy rainfall, even miles away, can funnel suddenly through steep drainages and confined canyon reaches. That rapid movement of water can reach hikers or campers who are not near the storm itself. The canyon's geography concentrates runoff into narrow channels, so conditions can change fast and without much warning.

# Current situation Park officials continue efforts to account for people who may have been affected. The public appeal is an active part of that effort because friends, family or other hikers may have information about travel plans, last known locations, or gear that could help locate individuals.

If you or someone you know was in the Bright Angel Creek corridor on August 29, provide the requested details to NPS Investigative Services Branch as soon as possible.
