In 1962, a family exploring the Hot Springs area of Big Bend National Park fitted together fragile mud fragments covered with unfamiliar marks. The find became a decades-long mystery, and the park’s own records preserve a careful lesson in how strange evidence should be handled.

The discovery began with a small movement in a very big landscape. During the winter of 1962, Donald Uzzell was climbing along a cliff above Tornillo Creek, opposite the Hot Springs Post Office and Motel. In an L-shaped cleft, he found a stack of pieces that looked like parts of a clay tablet. He passed the fragments down to the rest of his group—his mother and stepfather, Bernice and Charles Nickles, and his wife, Reva Uzzell—and they assembled the pieces like a jigsaw puzzle.
The assembled object carried more than 70 marks. Family members photographed it, then brought the pieces to Big Bend National Park headquarters at Panther Junction. That handoff placed an ordinary family outing at the center of a question that would travel through park files, university correspondence and magazine pages for years.
A park naturalist saw a different clue
Douglas Evans, the park’s chief naturalist in 1962, examined the fragments. In a letter preserved by the National Park Service, Evans described material made from sun-baked mud peeled from a recently soaked flat along Tornillo Creek after a flood. He recalled that the surface looked fresh, showed very little weathering and crumbled with handling. The pieces eventually broke down into dust while they were stored at the park.

Those physical observations form the strongest evidence in the surviving record. A fragile sheet of river mud with a fresh-looking surface fits a recent mark-making episode. The park’s account says people who saw the object in the office found no archaeological or historical significance in it. Ross Maxwell, Big Bend’s first superintendent, later wrote that conversations with people who had been children around Hot Springs before 1964 supported the possibility of a child making marks in the mud with a stick.
Why the mystery kept moving
The family who found the pieces kept asking questions. Bernice and Charles Nickles contacted Lewis R. Church, who shared photographs with a classical-languages scholar at Brigham Young University. That early exchange produced a cautious comparison with an old Greek alphabet. In 1969, the Nickles connected with Jack and Bernice McGee, writers who had taken an interest in reports of unusual inscriptions and objects around the United States.
From 1969 through 1977, the McGees corresponded with Big Bend staff and academics. In October 1970, they returned to the discovery area with the Nickles, the Uzzells and Miriam Lowrance of Sul Ross University. They collected dust and fragments from the crevice and sent samples to researchers. The expedition shows the human side of the story: people followed a puzzling object across years because its marks seemed to promise a larger history.

Some observers continued to read the marks as evidence of an ancient language. The NPS account records suggestions involving Greek, Hebrew, Phoenician and other scripts. In 1977, a translation attributed to Barry Fell described the writing with a mixture of ancient-language names. The park’s historian also records that Fell’s background was marine biology and that his language work was a personal interest.
What can be said with confidence
The Big Bend Tablet is a verified historical episode: a named family found fragments in a specific place, photographed them, delivered them to park staff and pursued an explanation. The object itself no longer survives. Its material, its rapid disintegration and the observations of park personnel are documented in the National Park Service record.
The ancient-inscription reading belongs to the story’s interpretation layer. It appears in correspondence and later claims, while the park’s material observations and local recollections point toward a recent drawing in dried river mud. The evidence invites curiosity and rewards restraint. A family found something genuinely odd; the surviving record helps explain why the oddity became a legend.
Today, Hot Springs remains a historic district at the confluence of Tornillo Creek and the Rio Grande. Visitors can see preserved structures, ancient pictographs and the spring that shaped the area’s human history. The tablet’s story adds one more human-scale detail to that landscape: a brief set of marks that turned a walk along a creek into a long investigation.
