Now, a sobering simulation has been created which shows exactly what happened to John Edward Jones, who suffered what many people labeled as the ‘worst death imaginable’ inside the Nutty Putty cave, in Utah.

YouTuber Zack D. Films created the animation detailing the gruesome death of the American, and how it came to be.

“A man was exploring the Nutty Putty cave in 2009 and he wanted to go through one of the tightest stretches called the birth canal,” the content creator explains.

“As he was going through it he noticed it was extremely tight but he had researched this part of the cave and he knew that if he just kept squeezing in he would safely make it through.

“However, he didn’t realize that earlier on he made a wrong turn and was actually in a different uncharted part of the cave. This stretch was so tight that the man became stuck upside down.

“They tried to rescue him for 27 hours but he eventually passed away and the cave was permanently sealed as his tomb.”

The cave was situated southwest of Utah Lake and 55 miles from Salt Lake City, the hydrothermal cave is known for being extremely tight, with narrow twists and tunnels throughout.Jones, who was 26 at the time of his death, decided to explore the cave with three of his relatives just days before Thanksgiving, but sadly never made it out.

He attempted to travel the ‘birth canal’ passageway before taking the wrong route and entering a tunnel that measured just 10 inches by 18 inches.

Jones had been squeezing through the tight space, believing that he would eventually make it through the other side, but he had no idea he had actually gone the wrong way.

Sharing an account of the rescue mission, Brandon Kowalis – who tried to free Jones – explained how a radio had been sent down so that the explorer’s family could speak to him.

“There was a request to take the radio down to John so that his family could say some words to him,” he wrote.

“I think it was his father, mother, and wife who spoke to him, telling him that they loved him and were praying for him and that his father had given him a blessing.

“His wife mentioned a feeling of peace, that everything would be OK. She talked to him about 5 to 10 minutes before I told her that we needed to get back to working at getting him out.”

Sadly, despite the team’s best efforts, Jones passed away after 27 hours of being stuck upside down, with many calling it the ‘worst death imaginable’.

It was deemed far too dangerous to try and retrieve his body, prompting the Jones family and the landowner to come to an agreement to permanently close the cave with the explorer still inside.
