Kola Superdeep Borehole: The Deepest Hole on Earth and the Myths It Created
The Kola Superdeep Borehole is more than just a record-breaking scientific achievement—it’s the foundation of one of the most chilling urban legends ever told.
A hole so deep it pushed the limits of human technology. A place where scientists made discoveries they never expected. And, if you believe the myths, the very spot where Soviet researchers accidentally drilled into Hell itself.
But how much of this legend is real? And what exactly did scientists find when they ventured into the deepest artificial hole on Earth?
Let’s dig in.
What is the Kola Superdeep Borehole?
The Kola Superdeep Borehole is a scientific drilling project in Russia's Kola Peninsula, near the Arctic Circle. It was part of a Soviet research effort to explore the Earth's crust by drilling as deep as possible.
What makes it so remarkable?
-
Location: Pechengsky District, Murmansk Oblast, Russia
-
Depth: 12,262 meters (40,230 feet)
-
Drilling Started: 1970
- Purpose: To study the Earth's crust and learn about its geological composition
At 7.6 miles deep, the Kola Superdeep Borehole remains the deepest artificial point on Earth—a record that has yet to be broken.
But while the project was a scientific triumph, it was also a journey into the unknown—one that sparked fear, speculation, and one of the most famous supernatural myths of all time.
How Deep is Too Deep? The Science Behind the Borehole
The goal of the Kola Superdeep Borehole was to reach the Mohorovičić Discontinuity—the boundary between the Earth's crust and mantle.
However, at just 40,230 feet, scientists encountered unexpected obstacles that forced them to stop.
The Extreme Heat
As they drilled deeper, temperatures soared beyond 356°F (180°C)—far hotter than predicted. This heat:
- Melted equipment and made drilling impossible
- Softened the rock, making it behave more like plastic
- Destroyed electronic sensors, preventing accurate readings
Unexpected Discoveries
While scientists didn't reach the mantle, they did uncover several strange findings:
-
Ancient Fossils at Extreme Depths – Microscopic plankton fossils were found six miles deep, proving that parts of the crust were once an ancient ocean floor.
-
Water in Solid Rock – Scientists expected deep layers to be dry, yet they found unexpected reservoirs of trapped water.
- Unknown Rock Formations – The layers were far less predictable than expected, challenging existing geological models.
The Borehole is Sealed Off
In 1994, the project was abandoned due to rising costs and extreme drilling conditions. Today, the borehole is sealed with a thick metal cap—which only adds to its eerie mystique.
This scientific closure might have been the end of the project, but for conspiracy theorists, storytellers, and horror fans, it was just the beginning of something much darker.
The Well to Hell: How the Kola Superdeep Borehole Became a Horror Legend
Sometime in the 1990s, rumors began circulating that Soviet scientists had heard something horrifying at the bottom of the borehole.
According to legend, when researchers lowered a microphone into the hole, they captured something no one expected—screams.
Not just one scream—thousands of tormented voices wailing in agony, echoing from deep within the Earth.
Terrified, the scientists supposedly abandoned the project and fled. The borehole was then sealed off permanently, preventing whatever lay beneath from escaping.
The Internet's Role in Spreading the Well to Hell Myth
Early Christian Radio & Email Chains
In 1995, a religious radio show picked up the story, claiming it was proof of Hell’s existence. The chilling “recording” of the screams was circulated in chain emails—spreading the legend across the world.
The Rise of YouTube and Creepypastas
By the 2000s, YouTube and internet forums revived the legend, mixing it with other creepypasta horror stories. Some content creators even altered the original “screams” audio, making it even more disturbing.
Other Viral Horror Myths That Followed
The Well to Hell legend paved the way for modern horror myths like:
-
Slender Man – A photoshopped horror figure that became real to some.
-
The Backrooms – A viral “creepy architecture” concept that spawned an entire horror franchise.
- Momo Challenge – A distorted WhatsApp avatar that caused mass panic.
Each of these stories follows the same pattern as the Well to Hell—an eerie blend of reality and fiction that people can’t stop believing.
Why Do People Believe in Stories Like the Well to Hell?
Even though the screams recording has been debunked, the legend refuses to die.
The Fear of the Unknown
Humanity has always been afraid of what lies beneath. From Greek mythology’s Underworld to Dante’s Inferno, the idea of a hidden realm of suffering beneath us is deeply ingrained in our psyche.
The Mystery of Abandoned Places
The Kola Superdeep Borehole is now an abandoned relic, sealed with a metal plate. The fact that it was left untouched only fuels speculation.
The Line Between Science and Horror is Thin
A hole deeper than Everest is tall?
Extreme heat destroying equipment?
Unexplainable rock formations?
The truth is already terrifying. The Well to Hell just gives it a supernatural twist.
Other “Gateways to Hell” Around the World
The Kola Superdeep Borehole isn’t the only place rumored to be a portal to another realm.
-
Darvaza Gas Crater (Turkmenistan) – A giant flaming pit, literally called “The Door to Hell.”
-
Aokigahara Forest (Japan) – A haunted forest at the base of Mount Fuji.
- Seven Gates of Hell (Pennsylvania, USA) – A mysterious series of abandoned tunnels where people claim to hear screams.
Every culture has places they believe connect to the supernatural. The Kola Superdeep Borehole is simply one of the most famous.

What Lies Beneath?
The Kola Superdeep Borehole remains one of the most fascinating places on Earth—a site where science and legend collide.
It is a place of groundbreaking discoveries, where scientists pushed deeper into the planet than ever before. But it is also a place where mystery thrives, where abandoned research and eerie myths have blurred the line between fact and fiction.
Even though the Well to Hell legend has been debunked, the fear of what lies beneath lingers. The borehole remains sealed, its depths unexplored beyond 12,262 meters. Could something truly strange be waiting down there? Or is the real horror simply how little we know about what lies beneath our feet?
One thing is certain—the deeper we dig, the more questions arise.
The Kola Superdeep Borehole is more than just the deepest hole on Earth—it is a symbol of human curiosity, scientific ambition, and the power of myth.
For decades, this forgotten Soviet project has captivated imaginations, serving as both a geological wonder and a modern horror legend.
Whether it is remembered as a scientific marvel or the infamous Well to Hell, one thing is certain—some places are best left unexplored.
