Deep beneath the earth, where sunlight never reaches and silence reigns, miners throughout history have heard something they can’t explain—a faint tapping on the tunnel walls, echoing through the dark. Was it the rock shifting? The sound of another miner’s pickaxe? Or… was it something else?
Welcome to the world of the Tommyknockers—cryptid miners of legend, whispered about in the flickering light of lanterns, said to haunt tunnels from Cornwall to California.
Who (or What) Are the Tommyknockers?
Tommyknockers are small, humanoid creatures from Cornish and Welsh folklore, believed to dwell in underground mines. When Cornish tin miners immigrated to the United States in the 1800s, they brought their superstitions with them—and soon, stories of Tommyknockers began to spread across the gold and silver mines of the American West.
Physical Description:
2–3 feet tall
Dressed like miners: boots, hats, tiny tools
Often unseen, but heard knocking on rock walls
But what do they want? That depends who you ask. Some say the Tommyknockers are the ghosts of dead miners, warning the living of danger. Others say they’re trickster spirits or ancient creatures guarding treasure.
Knocking Before Disaster: Real-Life Encounters
The most famous stories of Tommyknockers aren’t just strange—they’re eerie premonitions of disaster.
The Knockers of Central City, Colorado
In the 1850s, miners in Central City claimed to hear rhythmic tapping in the deep shafts—often just minutes before a collapse. Some dismissed it as coincidence, but others swore it was a warning. In one chilling case, a crew left their post after hearing the knocking, only for the tunnel to cave in just an hour later.
“The little men banged on the walls and saved our lives. I don’t care what the foreman says. I’ll leave every time I hear it.”
—An anonymous miner, 1883
The Calico Mine Warning
In California's Calico mines, a foreman in the early 1900s reported knocking sounds that moved through the tunnels like footsteps. He assumed it was a prank until the mine collapsed the next morning, killing three workers. Survivors insisted they had heard the knockers trying to warn them.
Helpers or Harbingers?
Not all Tommyknocker tales are grim.
Miners also told stories of being guided to rich ore after hearing knocks. Others left offerings of food—especially crusts of bread—in hopes of gaining the creatures' favor. Some old miners refused to enter a tunnel without first saying a prayer or tossing a coin to “the little folk.”
One 1921 report from a Nevada silver mine describes a worker being led by a series of knocks that led him straight to a new vein of ore—one that made him rich.
Are They Real?
Skeptics say Tommyknockers are a psychological effect—a way for miners to explain the strange noises of the underground world. But even modern-day workers in abandoned mines report phantom knocking where no one should be.
In 1956, the U.S. Bureau of Mines attempted to dissuade belief in Tommyknockers, calling it “dangerous superstition.” Miners protested so strongly that some companies officially recognized the spirits as part of mine culture.
Pop Culture: Stephen King & Beyond
You may know the name from Stephen King’s 1987 novel The Tommyknockers, which imagined them as alien beings. But King borrowed the name from real miner folklore. While his version is science fiction, the legends of the knockers are far older—and much more rooted in true accounts.
Have You Heard the Knock?
Whether they are ghosts, elementals, or something else entirely, Tommyknockers occupy a unique space in the world of cryptids: part protector, part poltergeist, always watching from the shadows of the earth.
Have you ever worked underground? Heard the tapping of something that wasn’t there? The next time you enter a dark tunnel and hear a knock—you might not be alone.
