Underground Base: Anatomy of an Underground Base — Real, Speculative and Mythic

An underground base can be the Cheyenne Mountain Complex — real, documented, visitable. It can be Dulce Base — claimed by a single unverified informant, without physical evidence. Or it can be the sacred chamber of a spiritual tradition. All three versions coexist in the cultural imagination and deserve separate — and careful — treatment.

Definition and Typology: Not All Underground Bases Are the Same

The term 'underground base' groups very different realities that deserve careful distinction. Type 1: documented military and government installations — NORAD's Cheyenne Mountain Complex in Colorado, continuity-of-government bunkers across the US, the Soviet Metro-2 beneath Moscow, Cold War underground nuclear weapons complexes in multiple countries. These exist, are partially documented, and some are even visitable.

Type 2: classified military installations whose existence is inferred or partially confirmed, but whose details are secret — what occurs at sites like Indian Springs (today Creech Air Force Base) in Nevada, the underground facilities of the Nevada National Security Site, and various facilities whose names appear in declassified documents but whose contents remain classified. These probably exist in scale and nature beyond what is public.

Type 3: installations claimed by unverified informants, without independent documentary or physical evidence — Dulce (New Mexico), Montauk (Long Island), and the multiple 'bases' described in SSP (Secret Space Program) movement narratives. In this category, the evidence chain is weak and informants are typically unverifiable. Type 4: sacred underground chambers from spiritual traditions — Agartha, Shambhala, Edgar Cayce's Hall of Records — which exist as spiritual and cultural narratives with centuries of history, without necessarily claiming a specific and verifiable physical location.

The Real Engineering of Underground Military Bases

Building a large-scale underground installation is an engineering undertaking of extreme complexity and enormous cost. The Cheyenne Mountain Complex, built between 1959 and 1966, required the removal of 700,000 tons of granite. The structural solution for nuclear pressure wave absorption — 15 buildings mounted on 1,319 steel springs, each spring 45 cm in diameter with 15 cm deflection capacity — is a work of exceptional precision engineering. Total cost was 142 million dollars at the time (equivalent to more than 1.3 billion in 2024 values).

The Raven Rock Mountain Complex (Site R) on the Pennsylvania-Maryland border is another example of a real and documented installation: an alternate command base for the American government, excavated between 1950 and 1953, with approximately 716,000 m² of underground space. It includes three four-story buildings suspended by steel springs, air ventilation and filtration systems, water reservoirs, and its own power generation. It was partially documented in investigative journalism books like Garrett Graff's Raven Rock (2017).

The USSR built similar systems on an even larger scale. The Yamantau Mountain complex in the Urals was identified by American satellite imagery in the 1990s as an underground construction project of enormous scale — estimates suggest capacity for tens of thousands of people. When the US Congress questioned the State Department about Yamantau, the Russian government refused to reveal the complex's function. This is documented fact — but what is inside Yamantau is, as far as is publicly known, unknown.

Dulce Base: Anatomy of a Narrative Without Evidence

Dulce, New Mexico, deserves detailed analysis as an archetypal case of underground base narrative without verifiable evidence. The story began with Paul Bennewitz, an Albuquerque businessman who, in the early 1980s, claimed to have picked up enigmatic radio transmissions from a secret air base near Dulce. The story gained elaboration when Thomas Castello — described only as a former base security guard — provided accounts of seven underground levels, genetic experiments and collaboration with alien entities.

There is a documented and disturbing layer to this story that is frequently obscured by speculative elaboration: Paul Bennewitz was effectively 'worked' by AFOSI (Air Force Office of Special Investigations) operatives. Richard Doty, an AFOSI agent, confirmed in interviews that he and others fed Bennewitz deliberate disinformation to steer him away from investigations into real classified technology at Kirtland Air Force Base. This episode, documented in books like Mark Pilkington's Mirage Men (2010), is a real case of government disinformation that enormously complicates evaluation of Dulce claims.

The question this raises is important: in an environment where deliberate government disinformation is documented, how do we distinguish narratives that are pure fabrication from narratives that are fabrications created deliberately to conceal something different? This is exactly the type of ambiguity that makes narratives like Dulce persistent and difficult to evaluate — and that is exploited by communities that use the impossibility of falsification as evidence of active cover-up.

D.U.M.B.s: Deep Underground Military Bases

In the vocabulary of underground base narratives, the acronym DUMB (Deep Underground Military Bases) designates a hypothetical network of interconnected underground installations in the United States — and potentially other countries — that goes far beyond what is publicly recognized. In more elaborate versions, this network would include hundreds of facilities connected by high-speed magnetic train systems, built at depths of several kilometers, capable of housing large populations for years.

Evidence for the DUMB network as described in more elaborate narratives is consistently weak: unverified informant testimony, interpretations of government construction contracts that could have multiple explanations, and inferences from industrial accidents whose conventional explanation is questioned. FOIA documents about existing military underground facilities reveal significant installations — but consistent with conventional military purposes, not the scale and nature of the DUMB network described.

What is documented: the American government maintains a Continuity of Government (COG) Program with underground facilities at multiple locations, some public (Greenbrier, Raven Rock) and others classified. The scale of this program is unknown in its details. This is distinct from the complete DUMB network of SSP narratives, which includes joint facilities with alien entities and technology far beyond conventional.

High-Speed Tunneling: The Real Technology

A recurring element in underground base narratives is the existence of high-speed train systems (sometimes called underground Vactrain or MagLev) connecting installations around the country through tunnels bored by nuclear tunneling machines — a technology that was in fact developed and patented in the 1970s by Los Alamos National Laboratory. US Patent 3693731, filed in 1972, describes a 'nuclear subterrene' that would melt rock ahead of it using a compact nuclear reactor.

This technology was developed but there is limited evidence it was deployed at scale. The Los Alamos nuclear tunneling program produced prototypes and technical publications, but there is no evidence that long-distance tunnels were built with this technology. The cost, radioactive logistics, and cooling challenges would be enormous even with available technology.

What actually exists at impressive scale: CERN's Large Hadron Collider (LHC) in Geneva has a circular tunnel of 27 km at 100 meters depth. The Gotthard Base Tunnel, inaugurated in 2016 in Switzerland, is 57 km long and is the world's longest railway tunnel. Norway maintains extensive underground storage infrastructure for weapons and fuel in mountain-tunneled facilities. Large-scale underground engineering is real and reaches impressive dimensions — but within known parameters, not the transcontinental scale of the most elaborate narratives.

Underground Bases Around the World: Documented Cases

Beyond American examples, multiple countries maintain or have maintained significant military underground installations. Israel maintains the Kirya Subterranean Complex in Tel Aviv, described in reports as Israel's largest underground military installation, with multiple floors beneath the Ministry of Defense headquarters. The country also maintains classified underground installations at undisclosed locations related to its nuclear program.

Sweden, during the Cold War, built one of the world's most extensive networks of military bunkers and underground installations proportional to its population. The Linköping Aeronautical Museum includes sections inside an underground complex that was a military aircraft hangar. The Swedish Air Force operated aircraft from runways built on normal roads, with aircraft stored in rock-excavated hangars — a documented and public survival strategy.

China has built vast underground installations for its nuclear arsenal — the 'Underground Great Wall', estimated by Georgetown's Center for Strategic and International Studies in 2011 as possibly 4,800 km of tunnels. Satellite imagery and leaked Chinese documents confirm the existence of an extensive system, though its exact scale and contents are unknown. The Chinese case is perhaps closest to a real DUMB network — not because it involves alien technology, but because its scale and purpose are not fully publicly known.

The Psychology of Belief in Secret Bases

Why does the idea of secret underground bases with extraordinary purposes persist with such force in contemporary culture? A psychological analysis reveals multiple layers. First, anchoring in verified reality: underground military bases do in fact exist, governments do conceal information about them (documented), and some revelations have confirmed what was previously denied (Area 51, Greenbrier). The gap between what is documented and what is claimed is real, but the fact that some 'conspiracy theories' proved true creates an 'if X then maybe Y' logic.

Second, the narrative appeal of the underground: as explored in the Inner Earth node, the underground is a universal archetype of mystery, hidden power and forbidden knowledge. Secret underground bases are the technological and modern version of this archetype — substituting wizards and dragons with scientists and alien entities, but maintaining the narrative structure of hidden power below the surface that is beyond the reach of the ordinary citizen.

Third, justified and amplified distrust: real cases like MKUltra, Tuskegee, COINTELPRO, and the suppression of Area 51's existence for decades demonstrate that governments can maintain secrets about activities that violate rights and exceed legal mandates. This legitimate distrust, when amplified without proportionality criteria, can lead to accepting extraordinary claims with ordinary evidence.

Underground Bases in Fiction and Their Cultural Impact

The representation of underground bases in science fiction and entertainment has profoundly shaped how the public imagines them — and, by extension, what they expect to find in non-fictional narratives. From Spectre in James Bond films' underground control rooms to Marvel's S.H.I.E.L.D. facilities, from The X-Files to Independence Day's military bases, fiction has established a powerful visual iconography that precedes and influences expectations about real secret facilities.

Stranger Things, as mentioned, explicitly based parts of its narrative on Project Montauk and underground base narratives with secret experiments. When the series becomes cultural mainstream, what was niche conspiratorial becomes a widely shared cultural reference — creating a familiarity that can make narratives seem more plausible through their cultural ubiquity.

The fictional series Dark, a German Netflix production, explores underground facilities and time travel in a way that resonates with Montauk narratives explicitly for those familiar with the source material. The artistic quality of these productions creates a halo of narrative plausibility that spills into non-fictional contexts. This phenomenon — where high-quality fiction normalizes speculative premises — is an aspect of the contemporary cultural environment that deserves critical attention.

Critical Reading: How to Evaluate Base Claims

An evaluation methodology for underground base claims should consider multiple criteria. First, source verifiability: can the informant be identified by name, professional background, and independent confirmation of their identity and experience? Thomas Castello and many other Dulce informants do not pass this basic test. Second, internal consistency and consistency with available data: are the claims internally consistent? Do they conflict with verifiable public data such as deck logs, satellite records, or geological documentation?

Third, proportionality of evidence to claims: the magnitude of the claim requires corresponding evidence. Claims about classified military installations with advanced technology require more evidence than claims about conventional military installations. Claims about collaboration with alien entities or massive-scale human experiments require extraordinary evidence — and no evidence at that level has been publicly presented for any specific installation.

Fourth, more parsimonious alternatives: before accepting an extraordinary explanation, consider whether simpler explanations are sufficient. Seismic anomalies in Nevada are better explained by tests at the Nevada National Security Site than by alien bases. Sightings of unidentified objects over military facilities are better explained by classified experimental aircraft tests — which are real and documented — than by alien aircraft.

Connections in the AwakenMap

The Underground Base node is one of the most centrally connected in the AwakenMap precisely because it represents the hypothetical physical infrastructure of multiple narratives. With Dulce Base, through the most cited specific installation in human-alien collaboration narratives. With DUMBs and Deep Underground Military Bases, through the concept of installation networks. With the ICC, through the role of bases as terrestrial operational centers of the Interplanetary Corporate Conglomerate.

With the Separatist Nazi Group, through speculation that underground Nazi bases built at the war's end — in Argentina, Antarctica, or other locations — provided the infrastructure or knowledge for subsequent American installations. With the Secret Space Program, through the role of bases as departure and arrival points for missions that would bypass the public space program.

The specific contribution of the Underground Base node in the AwakenMap lies in its capacity to be simultaneously documented (Type 1) and completely speculative (Types 3 and 4), maintaining the productive tension between verified and imagined that characterizes the map's best nodes. Exploring this node rigorously is an exercise in distinguishing fact from myth in an area where the two coexist in uncommonly close proximity.

Critical reading

This theme should be read in layers: documented facts, historical hypothesis, spiritual narrative, UFO culture and speculation. The goal here is to expand inquiry without turning lack of proof into certainty.

FAQ

Is Cheyenne Mountain still operational?

Yes, but with a reduced role. The complex was placed in standby mode in 2006, when NORAD transferred most of its operations to Peterson Space Force Base (formerly Peterson Air Force Base), a few kilometers away. Cheyenne Mountain was reactivated for backup operations in 2015, when General Gortney declared that its electromagnetic pulse (EMP) resistance capabilities made it preferable to Peterson for survival in cyberattack and EMP attack scenarios.

What is Raven Rock and what is its function?

The Raven Rock Mountain Complex (Site R) on the Pennsylvania-Maryland border is one of the US's most significant Continuity of Government installations. It was designated as an alternate bunker for the Secretary of Defense and other military leaders in case of Washington's destruction. It is real, documented in Garrett Graff's Raven Rock (2017), and is still operational as part of the COG (Continuity of Government) program. Its existence has been acknowledged by the American government.

Did Project Montauk really happen?

There is no verifiable evidence of mind control, teleportation or time travel experiments at the Montauk base (Camp Hero) on Long Island. The base did exist as an Air Force installation and was decommissioned — today it is a state park. Preston Nichols and Peter Moon's claims about secret experiments are based on 'recovered memories' without corroborating documentation. Stranger Things was narratively inspired by Montauk, but is declared fiction.

Could governments keep bases with alien technology secret?

Maintaining secrecy about conventional advanced technology is documented (Area 51, F-117, B-2). Maintaining secrecy about technology radically different from the known — including collaboration with non-human entities — would require compartmentalization and scale of concealment without historical precedent. The difficulty grows with the number of people involved. This does not make it impossible, but requires extraordinary evidence proportional to the extraordinary claim — evidence that does not exist in the verifiable public record.
