Human Remains Found in Grand Canyon Near Site of Intense Flash Floods - Newsweek

Human remains were recovered Monday in Grand Canyon National Park, near Crystal Rapid on the Colorado River, according to the National Park Service (NPS).

The discovery comes as officials continue searching for hikers swept away during last month’s catastrophic flash flooding.

Park rangers responded to the report on September 14 and recovered the remains from the inner gorge, roughly 10 miles downstream from Phantom Ranch, according to NPS. The remains have not yet been identified, and investigators say more information may emerge as the Coconino County Medical Examiner’s Office conducts its assessment.

The remains were transferred to the medical examiner’s office in Flagstaff, which has not released additional details.

“The person's identity, as well as their cause and manner of death, were not immediately known,” NPS told Newsweek.

The remains were discovered near Crystal Rapid, a turbulent stretch of the Colorado River that has been central to recent search‑and‑rescue operations.

According to NPS, law enforcement rangers responded to the scene Monday and recovered the remains before transferring them to the Coconino County Medical Examiner’s Office. Officials have not disclosed the condition of the remains, the estimated postmortem interval, or whether any personal effects were found.

The discovery occurred in the same corridor where search teams have been looking for Timothy Allen Smith, a 53‑year‑old hiker swept away during the August 29 flash flood.

While officials have not confirmed whether the remains belong to Smith, his wife acknowledged the development in a Facebook post, writing, “We are aware that the Grand Canyon found remains yesterday.”

The medical examiner has not responded to multiple media inquiries, and NPS says it has no additional information.

The discovery's location deep in the inner canyon has complicated recovery efforts. The area is accessible primarily by river or strenuous backcountry routes, many of which remain damaged or closed.

Drone teams from the Coconino County Sheriff’s Office assisted in earlier search phases, and it referred Newsweek to the National Park Service when approached via email.

Last month’s flash flooding in Bright Angel Canyon unleashed a destructive torrent that killed two hikers—John Giusti, 46, and Brent Rosenkranz, 42, both of Granbury, Texas—and left their companion, Timothy Allen Smith, missing.

The flood struck around 2:30 p.m. on August 29, destroying footbridges, ripping metal structures into the Colorado River, and severely damaging trails, campgrounds, and critical infrastructure.

Emergency crews rescued roughly 80 people from the canyon during the flooding. The deluge also knocked out the Transcanyon Waterline, forcing Stage 4 water restrictions on the South Rim and prompting closures of Phantom Ranch, Bright Angel Campground, and the North Kaibab Trail.

Images released by NPS show bridges swept away, debris lodged in the river, and inundated trails rendered impassable.

The flooding triggered an ongoing series of evacuations coordinated by NPS and the Arizona Department of Public Safety, with the American Red Cross helping evacuate residents to the South Rim.

Officials warned that additional thunderstorms could cause more flash flooding, debris flows, and rockfall—conditions that continue to complicate search efforts and infrastructure repairs.

The Grand Canyon consistently records one of the highest numbers of missing‑person reports among U.S. national parks. The park receives an estimated 200 to 220 missing‑person reports each year, according to a report from the New York Post.

Records from 2018 through early 2023 show more than 1,100 reports, though most are resolved quickly as search‑and‑rescue teams locate hikers who became disoriented, injured, or delayed.

The Department of Interior told Newsweek that it does not track a reliable historical average for unresolved disappearances in Grand Canyon National Park. It did confirm that one person reported missing in July 2025 has still not been found. Thomas Daniel Gibbs, 35, of Freehold, New Jersey, vanished after heading into the Grandview Trail and Horseshoe Mesa area.

Gibbs was last heard from on July 22, 2025, and authorities later found his Tesla Cybertruck parked at Grandview Point on the South Rim. Despite extensive search efforts and public appeals for information, authorities have not located him.

As of now, there are two open missing‑person cases at the park, a number that could change once the medical examiner completes the review of the individual recovered Monday night.

Only a small fraction of cases result in long‑term disappearances or fatalities, often tied to the canyon’s extreme environmental hazards. Summer temperatures in the inner canyon can exceed 120°F, creating dangerous conditions for dehydration and heat stroke.

Rugged terrain, steep elevation changes, and strenuous return hikes challenge even experienced hikers. Sudden monsoon storms can transform normally manageable creeks into deadly flood channels, as seen in the August 29 event.
