Author’s Note: You’ll notice a number of articles like this on the site in which we use AI or LLMs to perform some in-depth analysis. When we do this, we usually work with the machine to write the report. Sometimes we go back and add color, but lately I try not to do that.
When I use the machine to write I prefer to write a long author’s note like this and keep the report clearly the report. It’s not right to say it’s all AI. This report took me about 8 hours or so…granted…just two years ago it would have taken two days and two people…
I don’t mind the machine writing down the results. It’s a calculator, we don’t rewrite our calculator’s results, but it’s not so good at adding the color. So, let me add the color.
This report is really exploring the Cryptoterrestrial hypothesis. Which we at Fortean Winds feel strongly is one component of a larger, complex phenomenon.
Within the Cryptoterrestrial hypothesis, the subterranean connection to UAP is often discussed, and we wondered if we could find a data-driven connection….we did.
What I find interesting about these studies we do is that we try to use the most solid source data available, and in this case, we have great publicly available data. Thus, the results feel pretty solid to us.
This study shows there is a correlation between ancient tunnel systems (such as Cahokia) and UAP sightings (NUFORC data). The correlation looks even stronger when we compare it to the analysis we ran at the end of the report which showed weak to no correlations.
The other correlation we found approaching statistical significance is that there are a higher amount of UAP sightings during full and new moon phases, and higher frequency in Spring and Summer.
The accomanying negative results are interesting.
There is often a curiousity (I know we were curious) about a connection between fault lines and sightings, but this dataset showed little.
That’s interesting. Tells us where to look…and where to not look.
Also, while we still suspect a strong correlation to magnetism. This particular study showed little.
Analysis: This correlation is supportive of the Cryptoterrestrial hypothesis as we ran the same tests against cave systems in general and there wasn’t a correlation.
Meaning there IS a correlation around tunnels systems ancient people made but not caves in general.
So, if it were an underground species one would think the correlation would exist in all subterranean spaces. Not just the ones around ancient sites.
I think we should look into some ancient tunnels…but you decide.
Objective
This report examines the hypothesis of a connection between Unidentified Aerial Phenomena (UAP) sightings and underground systems, particularly tunnel networks. Through a data-driven approach, we explore whether UAP sightings correlate with subterranean structures, geophysical features, and celestial timing.
Uncovering Patterns in UAP Activity
Our research aimed to answer a fundamental question: Are UAP sightings correlated with underground features and specific geographic patterns?
Data and Methodology
Our analysis relied on publicly available datasets and geospatial tools:
- UAP Sightings: The National UFO Reporting Center (NUFORC) dataset, containing over 80,000 reported sightings globally, formed the foundation of this study.
- Geophysical Features:
- Tunnels: We compiled data on historical and modern tunnel systems, focusing on known sites in the continental United States (CONUS).
- Karst Regions and Mining Sites: Geospatial data on caves and mining operations were sourced from the US Geological Survey (USGS).
- Fault Lines and Magnetic Anomalies: Data from USGS and the World Magnetic Model.
- Celestial Timing:
- Lunar phases from NASA SKYCAL.
- Meteor shower peaks from TimeandDate.com.
- Tools and Techniques:
- Geographic Information System (GIS) analysis for spatial correlations.
- Statistical testing (chi-square, correlation analysis).
- Machine learning models (Random Forest) to identify predictive patterns.
Key Findings
1. Tunnels: The Strongest Correlation
- UAP sightings consistently showed tight clustering near tunnels, with an average proximity of ~4 km in hotspot regions like the Midwest and Southeast.
- Spatial clustering metrics (mean neighbor distance ~4.31 km) further validated tunnels as a significant feature associated with sightings.
- Interpretation: Tunnels may act as conduits for electromagnetic phenomena, attractors for natural or cryptoterrestrial activity, or simply regions with heightened environmental sensitivity.
2. Karst Regions and Mining Sites: Weak Correlation
- Despite initial interest, UAP sightings showed no significant clustering near karst regions or mining sites.
- The average distance (~25 km) was comparable to other geophysical features like fault lines and magnetic anomalies.
- Interpretation: While these regions may host environmental anomalies, their role in UAP activity appears secondary.
3. Fault Lines and Magnetic Anomalies: No Correlation
- Statistical testing ruled out significant relationships:
- Fault lines: Pearson correlation coefficient of 0.05.
- Magnetic anomalies: Chi-square p-value of 0.80.
- Interpretation: While these features have been hypothesized to generate electromagnetic activity, their influence on UAP sightings was unsupported in this study.
4. Temporal and Celestial Patterns
- Lunar Phases: Moderate clustering during Full Moon and New Moon phases, with a chi-square p-value of 0.145 (approaching significance).
- Meteor Showers: Limited alignment, with no statistically significant clustering.
- Seasonality: Sightings peaked during Spring and Summer, likely influenced by environmental conditions or observational factors.
- Interpretation: Gravitational or atmospheric factors may play a secondary role, amplifying subterranean activity during key celestial events.
5. Latitude as a Predictor
- Latitude emerged as the strongest geographic predictor in Random Forest modeling, suggesting UAP activity clusters within specific latitudinal bands, particularly in the CONUS region.
- Interpretation: Latitude could correlate with environmental or observational factors, or even ancient migration routes of potential cryptoterrestrial entities.
Discussion
Tunnels and the Cryptoterrestrial Hypothesis
The strongest insight from our analysis is the clustering of UAP sightings near tunnels. This aligns with theories that underground systems might serve as:
- Shelters or Bases: Hidden zones for cryptoterrestrial beings or advanced technologies.
- Electromagnetic Conduits: Natural pathways for phenomena related to UAP activity.
- Cultural or Historical Markers: Sites with ancient significance that may draw attention.
Negative Results Narrow the Focus
Negative findings for fault lines, magnetic anomalies, and mining sites help refine our understanding, allowing us to focus on tunnels and latitude as primary factors.
Latitude and Celestial Timing
Latitude’s predictive power suggests geographic clustering that could reflect environmental or observational factors. Celestial timing, particularly lunar phases, offers intriguing leads that may amplify or coincide with subterranean phenomena.
Conclusion
This study provides compelling evidence that UAP sightings cluster near tunnel systems and exhibit patterns tied to latitude and celestial timing. While negative results for other geophysical features refine the scope, tunnels remain the most promising feature for further investigation. Future research should focus on:
- High-resolution mapping of tunnel systems in UAP hotspots.
- Field studies during predicted celestial events.
- Integration of additional geophysical and temporal data to test the cryptoterrestrial hypothesis.
We had to focus on CONUS as those are the locations we had the best data to prove the strongest correlations. Yet, it would be interesting to see these exercises repeated in other countries. Please let us know what you find.
We’ve previously discussed the importance of latitude to UAP sightings and we found a very interesting connection and a specific latitude band with unusually high frequency. As you can see by the distribution chart above (the blue and red dots) there are certain bands of latitude with higher frequency.
AND it has an unusual amount of incidents of Ancient Tunnel plus UAP sightings.
That latitude band is between 35 and 45 degrees.
Clustering in Specific Latitude Bands:
- Sightings are not uniformly distributed across all latitude bands. There are noticeable peaks in specific bands, suggesting geographical preferences or clustering of UAP activity.
- These bands often encompass regions with significant human activity, infrastructure, or unique geophysical features (e.g., karst regions, fault lines).
Possible Environmental or Human Factors:
- The clustering of sightings in certain latitude bands may be influenced by proximity to tunnels or other infrastructure that acts as attractors or observation points. It could also correlate with population density or areas with higher sky visibility (e.g., rural areas free from light pollution).
- Geophysical anomalies, such as fault lines or karst regions, might also contribute to heightened activity in these bands.
Proximity to Tunnels and Other Features:
- When combined with the data on proximity to tunnels (from earlier charts), there may be overlap between latitude bands with high sightings and areas near tunnels. This could indicate a deeper connection between geophysical features and UAP activity.
Furthermore, when we analyze the entire dataset for higher frequency latitude bands (all NUFORC sightings through time in CONUS) we do see the same pattern and the same distribution. Below is a summary of a latitude analyis of all NUFORC sightings in CONUS.
Latitude Band Analysis of UAP Sightings
Analysis of the enhanced UAP dataset reveals significant clustering of sightings across specific latitude bands. Notably, the 40–45° latitude band exhibits the highest frequency of sightings, accounting for approximately 23% of all reported UAP incidents. This region covers key areas of the continental United States, including parts of the northern Midwest and Northeast, which are characterized by high population density, transportation infrastructure, and potentially relevant geophysical features.
Further, the latitude bands spanning 35–45° collectively represent nearly half of all sightings, reinforcing the hypothesis that these regions exhibit a disproportionate amount of UAP activity. Factors such as environmental anomalies, tunnel proximity, and observational conditions in these areas may contribute to the clustering.
This finding aligns with patterns observed in historical datasets and underscores the need for further geospatial and temporal analysis within these prominent latitude zones.
