Nathan Campbell was last seen on June 13, 2020, near Carey Lake, Alaska. He told his bush pilot that he was searching for the lost pyramid of Alaska. In May 2020, a small floatplane flew 41-year-old Campbell deep into a remote part of Alaska. During the flight, he told the pilot he was searching for Alaska’s lost pyramid. No one has seen Campbell since.
The National Park Service wasn’t told he was missing until mid-September, 2020. They began searching a remote area in Denali National Park and found supplies he had left at Carey Lake, where the plane had dropped him off. They also found a collapsed tent some miles away. Inside the tent was a damaged diary, likely chewed on by animals. (Source)
The diary didn’t offer many clues about what happened to him. It mostly described his daily camp activities. The last entry said Campbell had left the tent to “get water.” After finding the diary, Alaska State Troopers added Campbell to their missing persons list, but the notice didn’t give much more information.
On May 27, 2020, Campbell hired a small plane in Talkeetna, Alaska, to take him to a remote lake in Denali National Park. He brought basic camping gear, a lot of food stored in plastic tubs, and a satellite communicator to stay in touch with his wife and kids. His plan was to spend four months alone in the wilds of Interior Alaska.
Campbell chose a very isolated spot for his summer trip. The plane dropped him off at Carey Lake, a small blue lake surrounded by hundreds of miles of untouched wilderness. The area was tough to navigate, filled with dense bushes and deep beaver ponds. If he wanted to get to the nearest town, Lake Minchumina (which only has 13 residents), he would need to walk for a week through difficult terrain. If he was looking for solitude, he definitely found it.
However, Campbell wasn’t there just for a vacation; he had a specific purpose. During the long flight to Carey Lake, as they flew over the vast green forests below, Campbell opened up to his pilot, Jason Sturgis, about his plans for the summer.
“He was a pretty quiet individual,” said Jason Sturgis, the charter pilot who flew Campbell to Carey Lake, but Campbell revealed his interest in the rumored pyramid as the plane approached its landing after a long flight across the Alaska Range from near Talkeetna.
“His ‘Indiana Jones adventure’ is what he called it,” Sturgis said.
Campbell went to Carey Lake because he was searching for something very mysterious: the Black Pyramid. This huge underground structure is said to be four times bigger than the famous Great Pyramid of Giza in Egypt and is believed to be thousands or even millions of years old. Some conspiracy theorists think the pyramid is so important for national security that any evidence of it—and the military base that supposedly protects it—has been erased from satellite images.
For many years, bush pilots, trappers, and local people have traveled around Carey Lake, but a quick look through old newspapers from Fairbanks shows few mentions of a giant alien pyramid or a secret base in central Alaska. However, before Nathan Campbell arrived, nobody had really been searching for it. His reasons for looking in this remote part of Alaska, if you consider the strange logic of conspiracy theories, seem to make sense.
If you have not yet heard of the lost pyramid of Alaska, it is understandable. News of the structure has not crept into the mainstream media, but if you type “Alaska pyramid” into Bing’s search engine you will find the fictional structure has attracted plenty of attention from alternative and fringe media.
“World’s oldest pyramids found in Alaska shocks the scientific community,” New Earth Media headlined in 2017. “An underground pyramid giving out giant amounts of energy is being ‘covered up’ by the U.S. government, a documentary has revealed,” Daily Star reported in 2019.
“Traces of GIANT PYRAMID Beneath Alaska Uncovered by Journalist,” Russia’s, state-owned Sputnik News disclosed before going on to claim that “a nuclear blast that occurred in China nearly 30 years ago apparently led to a surprising discovery hundreds of kilometers away, in Alaska, where US government seismometers detected some peculiar geological anomalies, which in turn led a number of dedicated enthusiasts to pursue claims of a massive pyramid located far below the surface of the frozen peninsula.”
Sputnik cited as its source “the History Channel’s Ancient Aliens TV show journalist Linda Moulton Howe (who) was contacted by an ex-naval worker who told her on condition of anonymity that his father, an engineer, was able to see the pyramid while he was working on a top-secret government project.”

According to, Craig Medred, an independent Alaska journalist, There are no government projects, either secret or otherwise, within 50 miles of Carey Lake. If there were any, people would notice them because these types of projects need access, such as roads, airports, or even a landing spot for a helicopter. At the very least, there would need to be a clearing by a lake to bring in supplies by a floatplane.
All these things would be easy to spot in the wild and remote areas of Alaska. The story from Sputnik mentioned a Naval officer who supposedly said there was a large pyramid and that they “would go down to the base of a huge pyramid using the elevators.”
However, building elevators that go hundreds of feet underground would be a major construction project. This would be something that small planes flying over the area could easily see. Small, single-engine aircraft are as common in Alaska as cars are in the lower 48 states. Planes fly almost everywhere, all the time.
While Alaska has grown, and fewer people now own planes, the state still has six times as many private pilots and 16 times more planes per capita than the rest of the U.S., according to the Alaska Department of Transportation. The wild, undeveloped land of the state makes it easier, not harder, for planes to spot large construction projects from above. But those who believe in the idea of a hidden pyramid (or pyramids) in Alaska don’t see it that way.
As writer Anthony Tyler said in an article for The Last American Vagabond, “good parts of Alaska are ‘totally uninhabitable under their current climate conditions…and the government presence overall in the state is pretty overwhelming, with an Air-Force/Army joint base nearly the size of Anchorage right outside of the city itself.’”
He argued that it would actually make sense for the government to hide secret facilities in such remote areas. Tyler writes, “It would almost seem silly for the government to not utilize these tactical advantages.” He then raises the question, “Why can’t people see this from the sky?” The answer, according to him, is because “the pyramid is supposedly located underground.” And, even more surprisingly, he claims that it’s said to be “four times the size of Giza.”
Tyler even speculated on how the pyramid could have ended up hidden, saying that “the ability for an earthquake to subsequently collapse the pyramid in a sort of catacomb underneath the Earth’s surface would be theoretically possible if one took into account Charles Hapgood’s Earth crust Displacement Theory.” He admits, though, that “even this is a wild and unlikely truth.” Instead, the legend suggests that the pyramid is thousands of years old and “was not built by humans.” (Source)
In June, Campbell, who had just turned 41, decided to go on a solo adventure in the Carey Lake area, looking for pyramids. It’s unclear why he chose to do this alone. Sturgis, the pilot who dropped him off, said he felt uneasy about leaving Campbell without a set pickup date, but Campbell reassured him.
He told the pilot that he had a Garmin InReach device, which could help him communicate and share his location via GPS. Campbell explained that if he needed an early pickup, his wife would contact the pilot. Otherwise, he planned to stay until late August or early September.

Campbell was well-prepared, bringing along some large containers of food and a big backpack. Sturgis recalled that Campbell took fishing gear with him too, which was later found by park officials at Carey Lake. Campbell stayed in touch with his wife through the InReach device until mid-June.
After that, his wife stopped hearing from him. “It was a Friday she called me,” Sturgis said, explaining that she reached out in June, concerned because there had been no contact. Sturgis asked her for Campbell’s last known GPS coordinates, which showed that he was about five miles away from the lake. Unfortunately, Sturgis couldn’t land his floatplane in that area to check on Campbell. He advised Campbell’s wife to call a helicopter company to go and check the location.
Sturgis assumed the helicopter search would happen, but after a while, he forgot about the situation. “I just figured they did that,” he said, until September, when he got a call asking him to go and pick up Campbell. By that time, the man had been reported missing, and both the state authorities and the park service had begun searching for him.
Another pilot, David Lee, said the situation was strange. He had considered starting his own search mission for Campbell before the park service began theirs. “It’s pretty bizarre,” Lee said, adding that someone should have started looking for Campbell sooner, given that he’d been out of contact for nearly three months. However, he admitted, “I don’t know if it would have made any difference.”
Campbell is not the first to disappear into the wilderness on the north side of the park. About 50 miles to the east, a young man named Chris McCandless moved into an abandoned and deserted bus along an abandoned and overgrown road in April 1992.
The 24-year-old son of a comfortably well off East Coast family, McCandless fled into the wild for reasons that will never be known. Some have suggested he was struggling with mental illness. Whatever the case, McCandless was found dead of starvation in the bus in the fall of the year, and four years later writer John Krakauer authored a book portraying McCandless as a young man on a search for the meaning of life who died tragically after accidentally eating poisoned seeds.
The book became a bestseller that turned the dead McCandless into a mythical figure. The idea McCandless accidentally poisoned himself was eventually debunked, but it didn’t matter.
