In the spring of 1894, a man who had lost his right arm at the Battle of Shiloh sat down with the elders of the Hopi people and wrote down what they told him about what lay beneath the Grand Canyon. His name was John Wesley Powell, and he had already done what no white American had done before: he had led the first boat expedition through the canyon’s uncharted rapids in 1869. He had returned from that journey with questions, and now, as director of the U. S.

Geological Survey and the Bureau of American Ethnology, he was asking them formally. The elders told him that a great system of chambers, tunnels, and passages existed under the canyon. They said it had been there before human memory. They said it was inhabited.

They said there were entrances that only certain people knew how to find. When Powell asked how deep it went, they gave an answer he recorded in his official notes: it extended to the center of the earth. The Hopi are the oldest continuously inhabited civilization in North America. Their village of Oraibi, on the high mesas of northeastern Arizona, has been occupied since around 1100 A.

D. But their traditions say their history did not begin there. It began underground. The Hopi describe a cosmos organized around what they call the Four Worlds, each ending in catastrophe and each followed by another.

What happened between those worlds matters more than the metaphysics. Survivors of each destruction went underground, not symbolically but physically, entering the earth and living there until the surface was safe again. The beings who helped them were called the Ant People. They were described as small, with large eyes that could see in the dark, skilled at growing food in underground chambers lit by something other than sunlight.

They were described as older than the Hopi, already settled underground long before the Hopi ancestors descended to join them. They were not metaphor. They were reported as existing. Mainstream anthropology classified this as myth and moved on.

But in 1894, Powell made a decision to take it seriously enough to document it, and the records he left, along with other institutional documents, trace a pattern that the standard accounts have never fully explained. Fifteen years after Powell’s interviews, on April 5, 1909, the Arizona Gazette published a story that would become one of the most contested documents in American alternative history. It described the discovery of a massive underground citadel in the Grand Canyon by a team of Smithsonian Institution explorers led by a man named Professor S. A.

Jordan. According to the article, the team found a series of tunnels carved into the canyon walls, hundreds of feet above the river, reachable only by rope. Inside, they found a network of chambers extending more than a mile into the rock. They found mummified human remains.

They found stone tablets covered in hieroglyphic-like writing that matched no known Native American script. They found artifacts of copper and gold of unusual design. They found something stored in the deepest inner chambers, something the article described only vaguely, something the team chose not to describe fully in the public report. The Smithsonian has denied knowledge of this expedition in every era since the article appeared.

They say Professor Jordan never existed. They say no such discovery was made. They say the article was a hoax. But the Smithsonian’s archives from 1909 are not complete.

Specifically, the records of the Bureau of American Ethnology for the years 1908 to 1912 contain gaps that archivists have noticed but cannot explain. The missing records pertain to field expeditions in the American Southwest. When asked about the gaps, Smithsonian archivists have given various explanations: fire, flood, routine disposal of documents. What they have not provided is a full explanation of where those specific records went.

The Hopi word for the place under the canyon is sipu, or more precisely, sipapuni. It means the place of emergence, the place where people climbed from the underworld into this, the Fourth World. The Hopi do not describe it as a mythological location. They describe it as a real place with a physical entrance, a place that exists within the canyon itself.

In Hopi ceremonial life, smaller sipu symbols appear in the kiva, the underground ceremonial chambers central to their rituals. In every kiva, a small hole in the floor represents the original sipu, the gateway between worlds, the passage through which ancestors came. The fact that the Hopi perform their most sacred rituals underground in chambers that mimic the structure of the original underworld is not accidental. It is deliberate architecture of memory.

They built kivas to remember what they came from. Alexander Stephen, a Scottish trader who settled among the Hopi in 1880 and spent fourteen years documenting their life in extraordinary detail, attended ceremonies no outside researcher before or since was permitted to attend. He learned the Hopi language fluently and recorded things that later professional ethnologists, arriving as institutional outsiders, never accessed. He died in 1894, the same year the Hopi made their clearest statements about what lay beneath the canyon.

His journals were not published until 1936, edited by Elsie Clews Parsons. The published journals are roughly half the length of the original manuscript, held at the Museum of Northern Arizona in Flagstaff. Researchers who compared the two noticed categories of material Parsons chose to omit. Some was ritual detail considered too sensitive to publish.

But some involved Stephen’s record of conversations with an elder who told him things that were never published. The full contents of those unpublished portions are not known, because access to them is restricted by an agreement between the museum and the Hopi Cultural Preservation Office. The Hopi have the right to control access to their sacred knowledge. That right is not in question.

But it means the most complete record of what a close observer of Hopi life documented about the underground world in the 1880s and 1890s, the period immediately before the official documentation began, is not currently available to outside researchers. In 1935, a geologist named Edwin McKee was surveying a limestone layer in the inner gorge of the Grand Canyon when he and his team encountered something anomalous. At a depth of roughly 4,200 feet below the South Rim, in a section of the canyon wall inaccessible by any known trail, they identified a section of limestone face that showed signs of what McKee described in his field notes as artificial modification. The rock face showed evidence of having been worked and smoothed in a pattern consistent with deliberate shaping rather than natural erosion.

Behind the modified section, the team identified an opening approximately four feet wide and six feet high. They did not explore it. McKee reported the discovery to the U. S.

Geological Survey. The response, documented in the agency’s administrative correspondence from that year, was notably lukewarm. He was thanked for his report. The location was recorded.

No follow-up expedition was sent. McKee’s 1938 study of the Redwall limestone, which remains a foundational text in Grand Canyon geology, contains no mention of the worked rock face or the opening behind it. His field notes exist. The location exists.

The USGS correspondence exists. The omission from his published work exists. What does not exist is any explanation for why a geologist of McKee’s stature would document something anomalous and then decline to include it in his final study of the same rock layer in which he found it. The Grand Canyon receives about six million visitors a year.

They stand at the rim, take photographs, walk down the Bright Angel Trail, and marvel at the geological time. Hardly any of them know what the Hopi say is at the bottom. Hardly any know about the 1909 expedition, or McKee’s 1935 field notes, or the anomalous observation from 1894. The canyon has been there for five million years, the time it took the Colorado River to cut through the Kaibab Plateau.

But the rocks it cuts through are two billion years old. The formations beneath the Redwall limestone are older still. What the Hopi say lives in those formations has been there longer than the canyon itself, longer than the river, longer than the limestone it carved. What was there before the Grand Canyon became a canyon is a question the Hopi answered in 1894.

Powell wrote it down. The records exist. The gaps exist.

The question remains open.
