The world has been obsessed with a small metal monolith that seems to be popping up everywhere.
A new structure has now been uncovered on top of a hill in California.
A local newspaper in the small town of Atascadero has taken images of the mysterious monolith that has appeared overnight on Pine Mountain.
The Atascadero News wrote: "The three-sided obelisk appeared to be made of stainless steel, 10-feet tall and 18 inches wide. The object was welded together at each corner, with rivets attaching the side panels to a likely steel frame inside."
It's unclear whether this is a copy of the Utah monolith or whether it's the real deal.
Four men were seen removing the now infamous Utah monolith in the dead of night last week, according to an eyewitness.
Ross Bernards, a photographer and drone operator, says he has the real story on the mysterious metal pillar that appeared in the desert, before vanishing.
Writing on Instagram, he said: "If you're interested in what exactly happened to the monolith keep reading because I was literally there.
"On Friday, three friends and myself drove the six hours down to the middle of nowhere in Utah and got to the 'trailhead' around 7pm after passing a sea of cars on our way in."
After taking photos, they were about to leave at about 8.40pm, when they spotted another group arrive.
He went on: "Four guys rounded the corner and two of them walked forward. They gave a couple of pushes on the monolith and one of them said 'You better have got your pictures'.
"He then gave it a big push, and it went over, leaning to one side. He yelled back to his other friends that they didn't need the tools."
They carried it off and it hasn't been seen since...until now? They certainly appear to be the same structure, however it's unclear if they're the same height and metal.
Another monolith, which was clearly a copy, was discovered in Romania earlier, which thickened the plot considerably.
However, it didn't take long for the Romanian monolith to be removed.
A Romanian journalist called Robert Iosub confirmed that the monolith was missing, telling Reuters: "The 2.8 metre (9ft) tall structure disappeared overnight as quietly as it was erected last week."
There were some notable differences between the Romanian structure and the one that was thrown up in Utah.
For a start, the workmanship seems to have been a little slipshod on this European version, rather than the slick and seemingly seamless design of the first obelisk.
Now, the police are having a look into what has happened. To be fair, they've probably got as much chance as any of us have of finding out what has actually been going on this whole time.
