Six things you can verify yourself

Before you read another word — open Google Maps and confirm these are real.

  1. Isis Temple, Osiris Temple, Horus Temple, Tower of Ra, Tower of Set, Cheops Pyramid — all named on official USGS Grand Canyon maps. Plus Shiva Temple, Vishnu Temple, Krishna Shrine, Buddha Temple. Roughly 33 formations named after Egyptian, Hindu, and Buddhist deities. They are clustered.
  2. Hopi Salt Mines · river mile 62 to 62.5 · southeast side of the Colorado River. Officially closed to public per the National Park Service's published Compendium of Closures. Sits inside the same region as the named formations.
  3. The Sipapuni — the Hopi emergence point. A real travertine dome at the confluence of the Little Colorado and Colorado Rivers, four miles upstream. The Hopi have said for nine hundred years that their ancestors emerged from an underground world at this exact location. Access restricted.
  4. Public Law 100-91 · August 18, 1987. A federal Act of Congress restricted overflight of three U.S. National Parks. The Grand Canyon is one of them.
  5. The 1909 Phoenix Gazette article exists. Front page, April 5, 1909. Public domain. The reporter quotes G. E. Kinkaid stating the cavern is on government land and "no visitor will be allowed there under penalty of trespass."
  6. No archaeological survey of the named-formation cluster has ever been published. Not by the Smithsonian. Not by the National Park Service. Not by any university. In one hundred and sixteen years.

Now the case file.

I · The Geography On The Map

Pick up any United States Geological Survey topographic map of the Grand Canyon, currently in print and available at the visitor center. On the north side of the canyon, in a tight cluster around Ninety-four Mile Creek, Trinity Creek, and the area known as Haunted Canyon, you will find roughly thirty-three natural rock formations named after Egyptian, Hindu, Buddhist, and other ancient religious figures.

The cluster on the official USGS map

The formations were named by Clarence Dutton in his 1882 USGS publication Tertiary History of the Grand Cañon District. Dutton was a colleague of John Wesley Powell — the man who led the first Euro-American descent of the Colorado River in 1869 and went on to become the first director of the Smithsonian's Bureau of Ethnology. The official explanation given today is that Dutton just liked Egyptian mythology. The names are real. The cluster is real. The reader can verify it from any tourist map.

II · The Forbidden Zone

The Grand Canyon National Park's published Compendium of Closures and Restrictions identifies specific geographic areas closed to public access. Several of them sit in the same river-mile range as the named-formation cluster.

Officially restricted areas — NPS published document
  • Hopi Salt Mines — river mile 62 to 62.5, southeast side of the Colorado. Closed.
  • Hance Mine — south of Hance Rapid. Closed.
  • Anasazi Bridge — Furnace Flats area. Closed.
  • All natural caves within the park — closed without research permit.
  • Confluence of Little Colorado and Colorado Rivers — area of the Hopi emergence point. Access tightly restricted.

Each restriction has a defensible administrative rationale — endangered species, fragile cultural sites, indigenous sacred lands. The Codex records, without comment, that the clustering exists. The Egyptian-named formations, the indigenous emergence point, the closed mine zones, and the area described in the 1909 article all sit within a relatively small region. Almost all of it is closed to public investigation.

And then there's the air. In 1987, Congress passed Public Law 100-91 — an Act restricting overflight of three United States National Parks. Yosemite. Haleakala. The Grand Canyon. The stated rationale was preservation of natural quiet. The Grand Canyon is the only one of the three where the restricted airspace correlates directly with the geographic cluster described in this case file.

III · The 1909 Report

On April 5, 1909, the Phoenix Gazette ran a front-page story under the headline "EXPLORATIONS IN GRAND CANYON · Mysteries of Immense Rich Cavern Being Brought to Light · JORDAN IS ENTHUSED · Remarkable Finds Indicate Ancient People Migrated From Orient."

The article identified its source as G. E. Kinkaid — a thirty-year veteran of the Smithsonian, the first white child born in Idaho, and an explorer who had completed the Colorado River alone in a wooden boat from Green River, Wyoming to Yuma, Arizona. He had been looking for mineral deposits. Forty-two miles up the Colorado from El Tovar Crystal Canyon, he saw staining in the sedimentary formation about two thousand feet above the river bed on the east wall. The entrance, he said, was fourteen hundred and eighty-six feet down the sheer canyon wall.

"First, I would impress that the cavern is nearly inaccessible. The entrance is 1,486 feet down the sheer canyon wall. It is located on government land and no visitor will be allowed there under penalty of trespass." — G. E. Kinkaid, Phoenix Gazette, April 5, 1909

Inside, the article describes a hewn-rock chamber over five hundred feet long with cross-tunnels leading to large chambers. Copper instruments. Tablets covered in unidentified hieroglyphics. Rows of mummies in linen and rude cloth. Statues whose iconography resembled Egyptian and Hindu religious figures. "The great underground citadel of the Grand Canyon." The investigation, the article said, was led by a Professor S. A. Jordan of the Smithsonian.

IV · The Indigenous Record

The Hopi people have lived in northern Arizona for at least nine centuries. The village of Oraibi has been continuously inhabited since approximately 1100 CE. Their oral tradition — recorded systematically by Western ethnographers beginning in the late nineteenth century — places the origin of the Hopi people at a specific, mapped location in the Grand Canyon called the Sipapuni.

The Sipapuni is a real travertine dome on the Little Colorado River, about four miles upstream from its confluence with the main Colorado — within Grand Canyon National Park, in the same general region as the cluster of Egyptian-named formations. Hopi initiates undergo years of spiritual preparation before they are permitted to approach it. Outsiders are not granted access.

The Hopi cosmology describes the Sipapuni as the emergence point through which the ancestors of the Hopi rose from a previous world — the Third World — into the present Fourth World. The Zuni, Navajo, and other Puebloan peoples carry parallel emergence narratives placing the origin of humans at the same general site.

The narrative is, in its details, a creation tradition. It is also a thousand-year-old indigenous testimony that there is an underground passage beneath the Grand Canyon, that the entrance to it is at a specific location, and that the location is sacred and not to be approached by the uninitiated.

The official record acknowledges the Hopi belief and protects the site. It does not investigate the claim. The Codex records that the indigenous testimony pre-dates the 1909 article by approximately eight centuries — and identifies the same region.

V · The Official Position & Its Gaps

The Smithsonian Institution has been asked about the 1909 article continuously since at least the 1960s. The institutional answer is consistent. A 1999 letter from the Smithsonian's Office of Public Affairs states: "Neither G.E. Kincaid nor S. A. Jordan were ever employed by the Smithsonian… Please note, however, that this story is untrue." The article does use the term "Smithsonian Institute" rather than "Smithsonian Institution" — a name the Institution itself has never used. This is the principal documentary tell cited by those who consider the article fabricated.

"Please note, however, that this story is untrue"

Contemporary refutation arrived eleven days after the original story. The Coconino Sun in Flagstaff — the newspaper of record for the Grand Canyon's home county — ran a response titled "Looks Like a Mulhatton Story," referencing the prolific 19th-century journalistic hoaxer Joseph Mulhattan. In 2009, the Grand Canyon Historical Society concluded the article was likely a delayed April Fools' Day prank by an anonymous correspondent.

That is the institutional and journalistic record on the article itself. What the record does not address is everything else.

What the official position does not explain
  • The thirty-three Egyptian, Hindu, and Buddhist place-names on the official USGS map — and their clustering in one region of the canyon.
  • Why that exact region is, by official NPS document, closed to public access.
  • Why an Act of Congress was passed in 1987 to restrict the airspace above that same region.
  • The Hopi indigenous testimony — predating the 1909 article by eight centuries — that there is an underground passage at the same general site.
  • The absence, in 116 years, of any published archaeological survey of the named-formation cluster.
  • The absence, in 116 years, of any public expedition authorized to verify or disprove the 1909 article's central claim.

The Smithsonian's response is that "no Egyptian artifacts of any kind have ever been found in North or South America" — a statement that does not address whether any archaeological survey has been conducted in the area where they would, by the article's account, be located.

VI · What Is Not In The Record

The following observations are matters of documentary absence. None of them prove the 1909 article was true. All of them are unanswered.

The unfilled file
  • No published archaeological survey of the cluster of Egyptian-named formations exists, despite their being on the official USGS map for one hundred and forty-three years.
  • No FOIA-produced list of geological and archaeological surveys conducted in the restricted zones since the National Park was established in 1919.
  • No expedition publicly authorized in the intervening century to locate the cavern entrance the 1909 article describes — despite Kinkaid having given specific coordinates.
  • No institutional response addresses the geographic correspondence between the 1909 article, the USGS formations, the indigenous emergence point, and the restricted zones.
  • No explanation has been published for why the airspace above this specific area was placed under federal restriction in 1987.

The geography is admitted. The closure is official. The indigenous record is documented. The 1909 article exists. The institutional denial is on file. The investigation does not appear to have been conducted.

The Codex's editorial standard is that all of this belongs in the record together. We have surfaced what we can find. The reader is invited to consult the primary sources at the bottom of this page and to draw their own conclusions.
