Monument Valley, the iconic stretch of sandstone buttes on the Utah-Arizona border, has been described as the "scariest" national park in the United States in a recent feature recounting claims of UFOs, apparitions and other unexplained events in a former Navajo ranger’s memoir.

Stanley Milford Jr., who says he served more than 20 years as a ranger in Monument Valley and spent 11 of those years on a covert team that investigated UFOs and other paranormal reports on the Navajo Reservation, recounts numerous incidents in his book The Paranormal Ranger. "There’s much more to this world than we can imagine," Milford wrote, adding, "I quickly learned to shut my mouth and open my ears."

In the memoir and in interviews summarized by the feature, Milford describes episodes that he and colleagues interpreted as supernatural or extraterrestrial. He said he once felt an "invisible finger" move across his upper lip and heard two male voices nearby where there were no people. He described a chair flying across a room, a laptop battery slamming into a wall, coins falling and all landing heads-up, and an investigator finding a dollar bill with the word "die" written on it before a butcher's knife flew across the same room. Milford also recounts reports from administrative workers in Window Rock, Arizona, who said they heard disembodied voices and felt unseen hands touch them.

The accounts are presented as Milford's personal recollections and the reports he said he investigated while working on Navajo tribal land. Monument Valley is widely known for its dramatic sandstone formations and desert vistas and is a frequent subject of photography and film; Milford's memoir frames that landscape as the setting for the episodes he describes.

The feature places the valley's stories within a broader regional pattern of reported sightings. The desert town of Sedona, roughly 210 miles from Monument Valley, was reported to have 484 UFO sightings between 2000 and 2023, according to an Axios analysis cited in the piece, a rate well above the national average. A Sedona tour guide and self-described psychic quoted in the feature said he sees what he believes to be extraterrestrial activity nightly from his home and attributed some sightings to local geological "vortexes" and quartz-bearing ley lines; those explanations reflect local beliefs but are presented as the guide's views.

Federal incidents have also drawn attention to Arizona airspace. In January 2023, the Federal Aviation Administration reported that an F-16 fighter jet was struck in restricted airspace near Gila Bend by an "orange-white UAS," an uncrewed aerial system often described as a drone. The pilot was not injured and the jet was grounded for repairs; the FAA's report noted additional unidentified aircraft sightings over the Air Force's Barry Goldwater Range in the days following the collision.

Milford's accounts and related regional anecdotes have drawn attention because they combine long-standing Indigenous oral traditions, contemporary reports of unidentified aerial phenomena and individual claims of unexplained physical events. Milford, who identifies as part Cherokee and Navajo, describes having grown up on the reservation and says cultural knowledge aided his investigations, according to the memoir excerpts.

The feature that detailed Milford's experiences said Daily Mail reached out to him for further comment. The accounts in The Paranormal Ranger are presented as claimed experiences and investigations rather than as independently verified events. Monument Valley remains a major cultural and photographic landmark on Navajo land, and the memoir situates the valley's striking landscape as the backdrop for the episodes Milford recounts.
