# Where Are Alien Bases Reportedly Located? Underground Facilities & Dulce Base Claims

Reports of alien bases on Earth represent some of the most extraordinary claims in Unidentified Flying vehicle literature. Witnesses, whistleblowers, and researchers describe vast underground facilities, underwater installations, and mountain bases where extraterrestrials allegedly conduct operations hidden from surface humanity. While physical data remains elusive, the consistency of certain location reports and the detail of bystander descriptions warrant serious examination of these claims.

## Underground Facilities

### Dulce, New Mexico

The most infamous reported underground base exists beneath Archuleta Mesa near Dulce, New Mexico. Witnesses describe a multi-level facility extending miles underground, allegedly operated jointly by aliens (primarily Greys and Reptilians) and elements of the U.S. defense personnel-industrial complex. Former security officer Thomas Castello's controversial testimony details seven levels, with alien housing, genetic laboratories, and mind control experimentation areas. The lowest levels reportedly house thousands of humans in various states of captivity or genetic alteration.

### Area 51 Adjacent Regions

While Area 51 itself focuses on sensitive aircraft, witnesses report extensive alien facilities in the surrounding Nevada desert, particularly beneath Papoose Lake (S-4) and the Groom Mountains. These installations allegedly house recovered craft and facilitate technology transfer between aliens and human scientists. Bob Lazar's claims of working on extraterrestrial propulsion systems at S-4 brought widespread attention to these locations.

### Mount Shasta, California

This volcanic peak hosts numerous reports of underground alien bases, often associated with more benevolent beings. Witnesses describe encounters with tall, Nordic-type beings emerging from hidden entrances on the mountain. Local legends merge with modern Unidentified Flying Object accounts, describing vast cities within the mountain inhabited by advanced beings. The area experiences frequent Unidentified Flying Object sightings and anomalous phenomena reports.

### Pine Gap, Australia

This joint U.S.-Australian facility allegedly extends far beyond its acknowledged signals intelligence role. Witnesses report massive underground extensions housing alien technology and serving as a southern hemisphere hub for extraterrestrial operations. The extreme security and remote location fuel speculation about activities beyond conventional intelligence gathering.

## Underwater Bases

### Puerto Rico Trench

The Caribbean, particularly around Puerto Rico, generates numerous reports of Unidentified Submerged Objects (USOs) and underwater alien bases. Witnesses describe craft entering and exiting the ocean without splash or disturbance. The extreme depth of the Puerto Rico Trench (28,000+ feet) could hide extensive installations. Local fishermen report equipment malfunctions and mysterious lights from ocean depths.

### Catalina Channel, California

The deep waters between Los Angeles and Catalina Island reportedly conceal underwater alien facilities. Witnesses describe illuminated structures visible from aircraft and USOs traveling at impossible underwater speeds. The 1992 Malibu underwater anomaly, detected by sonar, shows artificial-looking structures that some interpret as base evidence.

### Lake Baikal, Russia

The world's deepest freshwater lake hosts numerous USO reports and allegations of underwater bases. Russian military divers reportedly encountered humanoid beings in silver suits at extreme depths. The lake's unique ecosystem and geological characteristics make it an intriguing location for hypothetical alien interest. state restrictions on certain areas fuel ongoing speculation.

### Bermuda Triangle

Beyond disappearance mysteries, witnesses report extensive underwater activity suggesting alien bases. Pilots describe USOs emerging from ocean depths at coordinates within the Triangle. Some theorists propose underwater installations exploit natural dimensional anomalies in the region. Electromagnetic anomalies and equipment failures correlate with areas of highest USO activity.

## Mountain Installations

### Mount Hayes, Alaska

Remote Alaskan mountains allegedly host alien bases, with Mount Hayes frequently mentioned by witnesses. The extreme isolation and harsh climate provide perfect cover for secret operations. Local pilots report structured craft entering the mountain through what appear to be camouflaged openings. Native Alaskan traditions include stories of star people inhabiting sacred mountains.

### Andes Mountains

The Andes range, particularly in Chile and Peru, features numerous reported alien base locations. Witnesses describe installations near ancient sites like Nazca and Machu Picchu, suggesting long-term alien presence. High-altitude plateaus provide isolation while proximity to archaeological mysteries implies historical connections. Chilean military personnel have reported encounters near suspected base locations.

### Himalayas

Tibet and surrounding Himalayan regions feature in both ancient texts and modern reports as hosting underground alien facilities. Chinese and Indian military forces allegedly monitor known entrance points. The extreme altitude and political sensitivity of border regions prevent civilian research. Some reports connect these bases to preservation of ancient knowledge and spiritual traditions.

### European Alps

Several Alpine locations, particularly in Switzerland and Austria, allegedly conceal alien bases within mountain tunnel systems. Witnesses report craft entering mountains through hidden portals and unusual military activity around certain peaks. The extensive natural cave systems and existing military installations provide cover for potential alien facilities.

## Dimensional Portals

### Sedona, Arizona

The famous vortex sites around Sedona reportedly serve as dimensional gateways rather than physical bases. Witnesses describe alien craft materializing from thin air at specific coordinates. Some experiencers report being taken through these portals to facilities existing in parallel dimensions rather than physical underground locations. The area's unique geology allegedly creates conditions favorable for dimensional interface.

### Skinwalker Ranch, Utah

This extensively studied location exhibits phenomena suggesting dimensional rather than purely physical alien presence. Witnesses report portals opening to reveal other landscapes, with beings and craft emerging before vanishing. The transient nature of phenomena suggests a dimensional access point rather than permanent physical installation.

### Mount Adams, Washington

ECETI Ranch near Mount Adams documents extensive aerial phenomena and reports of underground bases accessed through dimensional doorways. Witnesses describe beings materializing on the property and inviting selected individuals to facilities that seem to exist partially in another dimension. The consistent activity makes this one of the most active reported locations.

## Desert Installations

### Mojave Desert

The vast Mojave hosts numerous reported bases beyond Area 51. Witnesses describe installations beneath dry lakes, within mountain ranges, and accessed through abandoned mines. The desert's military presence provides cover while its geology offers stable underground construction conditions. Multiple independent witnesses report similar locations, suggesting either coordinated mythology or actual facilities.

### Australian Outback

Australia's remote interior allegedly conceals several alien bases, with Pine Gap being the most famous. Aboriginal traditions speak of sky beings and sacred sites that correlate with modern Unidentified Flying Object hotspots. The extreme remoteness and harsh conditions limit probe while providing perfect operational security for hypothetical bases.

### Sahara Desert

Less publicized but persistently reported, Saharan locations in Egypt, Libya, and Algeria allegedly host ancient alien facilities reactivated in modern times. Witnesses describe connections to ancient Egyptian mysteries and suggest certain archaeological sites serve as entrances to vast underground networks. Political instability in the region prevents systematic investigation.

## Urban Underground

### Los Angeles

Beneath Los Angeles, witnesses report extensive tunnel systems connecting to alien facilities. These accounts often merge with stories of military underground bases and ancient civilizations. Some experiencers claim abduction events beginning in LA homes end in underground facilities accessible through the city's infrastructure. The geological instability from fault lines supposedly doesn't affect these installations.

### Denver International Airport

Conspiracy theories about DIA include allegations of underground alien facilities connected to the airport's unusual underground tunnel system. Witnesses report non-human entities in restricted areas and connections to other underground installations via high-speed transport systems. The airport's peculiar artwork and massive underground space fuel ongoing speculation.

### London

Ancient tunnels beneath London allegedly connect to alien bases, with reports dating back centuries. Modern witnesses describe beings in the deep Underground system and connections to government facilities. The Thames River reportedly conceals underwater entrances to these networks. Historical accounts of spring-heeled Jack and other entities correlate with modern alien descriptions.

## Polar Regions

### Antarctica

Perhaps the most persistent reports involve extensive alien bases beneath Antarctic ice. Witnesses include military personnel from various nations' Antarctic programs describing discovery of ancient installations and ongoing alien activity. The extreme security, international treaties, and logistical challenges of Antarctic exploration make verification impossible while fueling intense speculation.

### Arctic Ocean

Beneath Arctic ice, witnesses report underwater and under-ice alien facilities. Russian and American military sources allegedly track USO activity around these bases. Climate change and ice melt reportedly concern aliens due to potential base exposure. The strategic military importance of Arctic regions provides cover for any anomalous activity.

## Verification Challenges

### documentation Limitations

Physical verification of reported bases faces insurmountable challenges. Government classification, remote locations, and advanced camouflage technology prevent civilian investigation. Witnesses providing specific coordinates often find heavy security or natural barriers preventing access. The absence of physical evidence doesn't disprove claims but frustrates serious research efforts.

### Disinformation Possibilities

Some researchers propose base location reports serve as disinformation, directing attention from actual sites or conventional classified facilities. The mixture of genuine observer experiences with deliberate false information creates an investigative maze. Discerning authentic reports from cover stories or delusions requires sophisticated analysis.

### Pattern Analysis

Despite individual account variations, certain patterns emerge: preference for geologically stable areas, proximity to water sources, correlation with ancient sacred sites, and clustering near military installations. These patterns suggest either consistent mythological construction or operational requirements for actual bases.

## Research Implications

### study Priorities

Limited resources force researchers to prioritize locations with multiple independent witnesses, physical anomalies, and historical consistency. Locations like Dulce, Mount Shasta, and Puerto Rico receive more attention due to persistent reports spanning decades. This prioritization may miss equally significant but less publicized locations.

### Technology Requirements

Proper base inquiry would require ground-penetrating monitoring system, underwater exploration vehicles, and access to restricted areas. The technology exists but remains unavailable to civilian researchers. Military and intelligence agencies possessing such capabilities show no interest in public disclosure of findings.

### Cooperation Needs

Serious investigation of reported base locations requires unprecedented cooperation between civilian researchers, government agencies, and international bodies. Current classification levels and national security concerns make such cooperation unlikely, leaving researchers dependent on eyewitness testimony and circumstantial evidence.

The global distribution of reported alien bases suggests either widespread mythological patterns or extensive extraterrestrial presence on Earth. Whether these locations represent physical installations, dimensional access points, or psychological phenomena, their persistence in human experience demands explanation. As technology advances and disclosure pressure mounts, some reported locations may eventually yield concrete evidence. Until then, researchers must carefully document reporter accounts while maintaining healthy skepticism about extraordinary claims lacking extraordinary evidence. The truth about alien bases remains hidden, whether in underground facilities, beneath ocean depths, or within the human psyche's depths.

The witness testimony and evidence from this incident provide crucial insights for contemporary Aerial Anomaly investigation.
