Quick Info
Deep beneath Archuleta Mesa near the small town of Dulce, New Mexico, lies one of the most persistent and controversial legends in UFO lore: a vast multi-level underground base where humans and extraterrestrials allegedly work together on genetic experiments, mind control, and other secret projects. Stories of grey aliens, reptilian beings, horrific underground chambers, and a violent 1979 confrontation have circulated for decades, fueled by alleged whistleblowers and leaked documents.
While no concrete physical proof has ever been publicly verified, the Dulce Base story has fascinated researchers since the 1980s and remains one of the most detailed and chilling underground base narratives in modern UFO history.
The Land and the Legends
Dulce sits on the Jicarilla Apache Reservation in northern New Mexico, a remote and sparsely populated area. Local Native American traditions have long spoken of strange lights, underground tunnels, and mysterious beings in the region. These older legends gained new life in the late 1970s when cattle mutilations and unusual aerial activity were reported across the basin.
Paul Bennewitz and the Birth of the Story
The modern Dulce Base legend began with Paul Bennewitz, a physicist and businessman in Albuquerque. In the late 1970s he became convinced he was intercepting alien communications and observing UFO activity near Dulce. He shared his findings with ufologists and even the U.S. Air Force. What Bennewitz didn’t know at the time was that elements within the Air Force Office of Special Investigations (AFOSI) allegedly fed him disinformation to discredit him and divert attention from other classified projects. His claims of a joint human-alien underground base spread rapidly through the UFO community.
Thomas Castello’s Alleged Testimony
One of the most detailed accounts came from a man claiming to be Thomas Castello, a former security technician at the base. In interviews and leaked documents (known as the “Dulce Papers”), he described a seven-level underground facility. Levels 1–3 were supposedly human-operated, while lower levels housed alien labs, genetic experiments, and holding areas for abducted humans and hybrids. He claimed to have seen horrific scenes, including vats containing human body parts and live experiments on captives.
“The lower levels were the worst. What I saw there still haunts me to this day.”

Castello said he eventually stole documents, photos, and video before going into hiding. His identity and the authenticity of his claims have never been independently verified.
Phil Schneider and the 1979 Shootout
Another dramatic claim came from Phil Schneider, a self-described government geologist and explosives expert. In the 1990s he publicly stated that he had helped construct Dulce Base and was present during a violent confrontation in 1979. According to Schneider, a team of human workers accidentally broke into an alien section, triggering a firefight that killed dozens of humans and aliens. He claimed to have lost fingers in the battle and showed scars he attributed to alien weaponry.
“They came at us with blue plasma bolts. It was a slaughter.”

Schneider gave lectures and interviews until his death in 1996, which some claim was suspicious. Many researchers later questioned his story due to inconsistencies and his personal background.
Alleged Base Layout and Activities
According to the various claims, Dulce Base is said to extend several miles underground with at least seven levels. Upper levels handle administration and human operations, while deeper levels supposedly house alien living quarters, genetic labs, and storage for abducted humans. Stories describe advanced technology, telepathic communication with greys and reptilians, and experiments involving human-alien hybridization.
Skepticism and Lack of Evidence
Despite decades of rumors, no verifiable physical evidence of Dulce Base has ever been presented. Investigations by independent researchers, journalists, and even some government insiders have found no concrete proof of an underground facility matching the descriptions. Many elements of the story have been traced back to disinformation campaigns aimed at Paul Bennewitz. While the legend remains popular in UFO circles, most mainstream analysts consider it an elaborate hoax or mixture of myth and exaggeration.
Timeline of the Dulce Base Legend
- Late 1970s – Paul Bennewitz begins reporting strange activity near Dulce.
- 1979 – Alleged violent confrontation between humans and aliens (per Phil Schneider).
- 1980s – Thomas Castello allegedly leaks documents and photos.
- 1990s – Phil Schneider goes public with lectures and claims.
- 2000s–present – The story continues to circulate online and in books, with no new hard evidence emerging.
Why the Dulce Base Story Still Fascinates Us
The Dulce Base legend endures because it combines almost every element of classic UFO conspiracy lore: secret government facilities, alien-human collaboration, genetic experiments, whistleblowers, and violent conflict. Whether it is entirely fictional, partially based on real classified projects, or something more, it remains one of the most detailed and chilling underground base narratives in modern UFO history. It raises big questions about secrecy, power, and what might truly be hidden beneath the surface of our world.

What Do You Think?
After reading the claims about Dulce Base, and watching the video above, what’s your gut reaction? I know this one is VERY controversial to a lot of people, but it's a great story I enjoyed reading up on. Do you think there could be any truth to the stories of underground alien-human collaboration, or is it all an elaborate hoax or disinformation? Why do you think this particular legend has lasted so long? At the end of the day this is still one of the most detailed, and controversial, underground base stories in UFO lore. I’d love to hear your thoughts on it.
