When it comes to mysterious military installations shrouded in conspiracy, Area 51 often takes center stage in public imagination. However, for decades, another secretive location has attracted intense speculation and intrigue—Dulce Base, rumored to lie deep beneath a mountain in Northern New Mexico near the small town of Dulce. The claims surrounding this clandestine underground facility suggest that what happens there far surpasses anything attributed to Area 51, even involving alleged alien-human conflicts on multiple subterranean levels.

Origins of the Dulce Base Mythos

Talk about Dulce began to take shape in the 1970s, sparked by reports from Paul Bennewitz, a tech entrepreneur and UFO researcher. Bennewitz claimed to witness strange lights in the skies above New Mexico, which he believed were linked to secret activities at nearby military installations, especially Kirtland Air Force Base, some 180 miles away. Kirtland itself has a long history of classified projects, including its use during the Manhattan Project in the 1940s as a transport hub connected to Los Alamos National Laboratory.

Bennewitz’s theories took a darker turn after he met a woman who claimed she had been hypnotized, abducted, and taken to an underground lab where she was injected with a substance that allowed aliens to access her consciousness. Fascinated and determined to uncover the truth, he set up radio receivers to intercept strange signals, which he interpreted as communications from UFOs.

Despite his warnings of a potential extraterrestrial threat communicated to authorities in the late 1980s, Bennewitz’s claims were mostly dismissed skeptically. However, his work attracted the attention of UFO researcher William Moore, who expanded on Bennewitz’s ideas, suggesting that two alien groups—the benevolent Whites and the sinister Grays—had already made contact with Earth.

The Alleged Alien-Human Partnership Under Dulce

According to the lore, the Grays inhabit a sprawling underground complex beneath Archuleta Mesa Mountain near Dulce. The conspiracy goes further to assert that these extraterrestrials have struck a pact with the U.S. government, enabling them to carry out joint experiments on both humans and animals. This secret program is said to involve the testing and manipulation of consciousness, advanced biotechnology, and cutting-edge technologies far beyond contemporary human capabilities.

Reports refer to a multi-level underground facility where levels 5 through 7 house the alien inhabitants and sophisticated laboratories. This expansive base supposedly includes an underground subway system linking Dulce with other secret military and alien sites, including the infamous Area 51, stretching across a vast network of tunnels beneath the western United States—and allegedly connecting worldwide subterranean cities.

First-Hand Accounts: The Dulce Papers and Thomas Costello

Ex-security guard Thomas Edwin Costello’s detailed accounts, shared in the book The Dulce War: The Costello Confession, provide one of the most compelling insider narratives supporting the existence of this mysterious base. He recounts witnessing horrifying experiments and describes the strict security measures beneath the mountain—from biometric weight checks and magnetic-controlled elevators to alien signage blending human and extraterrestrial symbolism.

Costello claims to have secretly gathered photographic and video evidence inside the base before fleeing in 1979, materials now known in UFO research circles as the "Dulce Papers." Although these documents circulate widely among enthusiasts, their authenticity remains unconfirmed, shadowed by copyright and verification challenges.

According to Costello, the base conducts advanced biological experimentation, blending alien technology with human science on living beings. This includes using alien communication systems, technologies for mind control, and maintenance of strict medical surveillance protocols. The base itself is a labyrinthine structure, with controlled access moving passengers vertically through security checkpoints and elaborately guarded subterranean corridors.

The Continuing Mystery and Skepticism

Despite decades of testimony and conspiracy theories, no conclusive evidence has surfaced to definitively prove the existence of Dulce Base or its purported alien occupants. Many dismiss these stories as imaginative works fueled by paranoia, science fiction, or the natural human desire to explain mysteries beyond current scientific understanding.

Nonetheless, these accounts have persisted in popular culture and UFO research communities, blending folklore, alleged whistleblower testimony, and shadowy government secrets into a tantalizing narrative of a hidden war beneath our feet—one that might involve extraterrestrials, secret alliances, and the fate of humanity at stake.

The truth behind Dulce Base remains elusive, enmeshed in a complex web of conflicting reports, unverified claims, and a deep human fascination with the unknown. As with all extraordinary assertions, critical examination, skepticism, and open inquiry remain our best tools to unravel what may lie beneath the quiet mountains of New Mexico.
