It is a hole in the ground that became a tomb. For decades, the Nutty Putty Cave was a rite of passage for Utah scouts and college students from BYU. It was slippery. It was warm. It felt safe because it was so well-traveled. But since 2009, the nutty putty cave sealed entrance has sat under a thick slab of concrete, serving as a grim headstone for John Edward Jones.
John didn't just get stuck; he became part of the mountain.
If you hike up the hillside near Utah Lake today, you won’t see the entrance. You’ll see a plaque. You'll see a flat, grey patch of cement. It looks mundane, almost like a utility cover, but beneath that seal lies one of the most claustrophobic tragedies in modern exploration history. People still ask why they couldn't just "pull him out" or why the cave had to be destroyed for everyone else. The reality is much more haunting than a simple accident.
The night the Nutty Putty Cave sealed its fate
John Jones wasn't an amateur. He was a medical student, a father, and a former explorer who knew how to move his body. But on November 24, 2009, he made a fatal mistake in a section of the cave known as "Ed’s Push." He thought he was entering the "Birth Canal," a tight but manageable squeeze. He wasn't. He was in an unmapped, vertical fissure that narrowed into a literal dead end.
Imagine a finger sliding into a ring that is two sizes too small. That was John. He was upside down at a 70-degree angle. Every time he breathed out, gravity pulled him a fraction of an inch deeper into the "V" shape of the rock. When he breathed in, his chest expanded against the limestone, pinning him tighter.

Rescue workers didn't just stand around. They spent 27 hours fighting. They used a system of 15 pulleys and high-tech ropes. They actually managed to lift him a few feet at one point, but then a pulley failed. A natural anchor point in the rock shattered. John dropped back into the crevice. He died shortly after from cardiac arrest and the sheer physical toll of being inverted for over a day.
Why the recovery was abandoned
Most people assume that when someone dies in a cave, you just go get the body. Usually, that's true. But with the nutty putty cave sealed today, you have to understand the geometry of the "Bob's Push" and "Ed's Push" areas.
The rescuers were literally standing on John's legs to try and reach him. To get a deceased body out of a space that a living, breathing person couldn't navigate would have required breaking John's legs or worse. The risk to the recovery team was massive. The rock was "putty-like" and unstable—hence the name. After a consultation between the Jones family, the Utah County Sheriff’s Office, and the School and Institutional Trust Lands Administration (SITLA), the decision was made: the risk was too high.
John would stay there.
The logistical nightmare of the concrete plug
Deciding to close a cave isn't like locking a door. It's a permanent geographical alteration. The decision to keep the nutty putty cave sealed wasn't just about respect for the dead; it was about public safety and preventing "disaster tourism."

When the cave was open, it saw nearly 5,000 visitors a year. It was a zoo. People were getting stuck constantly. In fact, just a few years before the 2009 tragedy, two different people had to be rescued from the exact same spot. The cave was a known hazard that had been closed and reopened before. This time, the state wasn't taking chances.
The sealing process involved:
- Explosives used to collapse the ceiling around the area where John was located.
- Filling the entrance hole with a massive amount of concrete.
- A permanent memorial plaque placed on top to discourage people from trying to dig their way back in.
Honestly, it’s a bit weird to think that a popular hiking destination is now a graveyard. But for the caving community, it was a polarizing move. Some felt the cave should have remained open, arguing that one man's mistake shouldn't ruin the resource for everyone. Others saw it as the only moral choice.
What it’s like at the site now
If you visit the hills west of Utah Lake, the vibe is heavy. You can't hear the wind whistling through the cave anymore. The nutty putty cave sealed status has turned the area into a place of quiet reflection rather than adrenaline.

The terrain is desert-like. Scrub brush, dust, and heat. The "hole" is gone. In its place is a slab that looks remarkably small. It’s hard to believe a miles-long labyrinth sits right under your boots. There are no tours. There are no "secret entrances." Some local legends claim there are other ways in, but cave experts and the Sheriff’s department have been incredibly thorough in ensuring no one can pull a "stunt" exploration.
The legacy of Nutty Putty in the caving world
The closure changed how caves are managed in the West. Before 2009, Nutty Putty was basically a free-for-all. Now, caves on state lands are under much tighter permit systems.
The story of the nutty putty cave sealed is taught to every search and rescue trainee in the country. It’s a textbook case of "suspension syndrome" and the limits of technical rope rescue. It also serves as a reminder that "easy" caves are often the most dangerous because they lure in people who aren't prepared for the physical reality of tight spaces.
Actionable steps for modern explorers
If you're fascinated by the Nutty Putty story, don't go looking for a way in. It's over. Instead, use that curiosity to explore the underground world safely and legally.
Join a local Grotto
Don't be a "spelunker"—that's a term for amateurs. Be a caver. Join the National Speleological Society (NSS). They have local chapters (grottos) that will teach you how to move, what gear to wear, and how to respect the cave environment.
Understand your limits
The Nutty Putty tragedy happened because of a navigation error. If you are exploring, never go alone and always have three independent light sources. If a squeeze looks too tight, it is. Your ego is the most dangerous piece of equipment you carry.
Visit managed caves first
If you want the thrill of the squeeze without the risk of a permanent concrete seal, visit places like Timpanogos Cave National Monument nearby. They offer "Introduction to Caving" tours where rangers actually teach you the proper way to belly-crawl through limestone without getting stuck.
Respect the silence
If you do hike to the Nutty Putty site, remember it is a grave. The Jones family still lives with this loss. Treat the concrete seal with the same respect you would show at a cemetery. Leave no trace, take your photos, and understand that some places are better left to the earth.
The mountain has claimed its own, and the cement slab is there to make sure it doesn't happen again.
