You might be familiar with the whole mystery monolith thing now, given the recent discovery in Utah. But now, it seems some equally-as-strange scenes have just occurred in Romania...

The mystery of the monolith in Utah that you may have heard of started last Monday during a routine wildlife check...

Something that quickly took an extraterrestrial turn.

Officers spotted a mysterious monolith right in the middle of rural Utah.

The Utah Department of Public Safety took a helicopter over the desert when the strange sighting took place earlier this week.

They were helping the Division of Wildlife Resources do a routine count bighorn sheep...

When they suddenly noticed a strange-looking object on the ground.

The object appeared to come straight out of 2001: A Space Odyssey.

"One of the biologists spotted it, and we just happened to fly directly over the top of it," pilot Bret Hutchings said.

"He was like, 'Whoa, whoa, whoa, turn around, turn around!' And I was like, 'What.' And he's like, 'There's this thing back there, we've got to go look at it!'"

And there it was.

Right in the middle of a clearing in the rock stood the strange object.

Hutchings said it was easily "between ten and twelve feet high."

Although he admitted it didn't look like it had fallen to the ground...

But instead, placed there on purpose.

"We were kind of joking around that if one of us suddenly disappears, then the rest of us make a run for it."

Still, Hutchings thought the object was more than likely placed there by a human, rather than an extraterrestrial.

"I'm assuming it's some new wave artist or something or, you know, somebody that was a big 2001: A Space Odyssey fan," he said...

In reference to the 1968 film where a large black monolith appears to study early civilization.

Although it was all pretty exciting, the DPS quickly confirmed that it is illegal for any forms of artwork to be placed without permission...

"No matter what planet you're from," they said in a statement released Monday.

Well, this didn't stop people from visiting the eerie monument.

Tourists were quick to track down the monolith to investigate themselves and, of course, some wild theories were born as a result.

Speculation was rife as to what the monolith could be...

Or where it even came from in the first place. Let's take a look at some of the best theories born on the internet...

Firstly, it could be an art structure.

One of the more popular theories - and one supported by officials themselves - is that the monolith could have been made and placed by an artist.

Which artist though?

A gallery owner recently claimed the work may be a tribute to the art of the late artist John McCracken, who created similar-looking objects before he died in 2011.

A second theory was that it could be alien evolutionary device.

Thanks to its resemblance to the famous object from Stanley Kubrick's 2001: A Space Odyssey, many can't help but jump to a science-fiction conclusion.

Thirdly, it could be an alien probe.

Besides having some specific impact on the inhabitants of planet Earth, the monolith could "just" be an extraterrestrial probe, sent here to learn about our ways. But would placing it in the middle of the Utah desert be the best place to probe humanity?

However, others believe that it could be a Kubrick fan installation.

The visionary director left a profound legacy, garnering millions of fans around the world. As the monolith he devised for 2001: A Space Odyssey is one of the most famous objects in movie history, it's not out of the question that one of the director's followers decided to recreate it.

And, lastly, some believed that it could be a government "control device."

Because of course, they did. The American Southwest is rife with government military installations and mysterious bases like Area 51. Having the monolith be a part of some government experiment is a connection that's easy to make for any conspiracy-minded Internet dweller.

Of course, the actual government hasn't confirmed any of this.

But the DPS has warned people against trying to find it: "It is in a very remote area and if individuals were to attempt to visit the area, there is a significant possibility they may become stranded and require rescue."

But then, just to make this story even more mysterious...

The monolith suddenly vanished!

According to the New York Times, the monolith disappeared into thin air.

The Times reported over the weekend that the monolith had been removed - however, Utah authorities say they had no idea who removed it.

Utah's Bureau of Land Management confirmed the news.

In a statement, they revealed that the structure was removed on Friday evening by "an unknown party."


Posting to Facebook, the Bureau of Land Management wrote: "We have received credible reports that the illegally installed structure, referred to as the “monolith" has been removed from Bureau of Land Management (BLM) public lands by an unknown party. The BLM did not remove the structure which is considered private property. We do not investigate crimes involving private property which are handled by the local sheriff’s office."

One word. Aliens.

The post continued: "The structure has received international and national attention and we received reports that a person or group removed it on the evening of Nov. 27." It was definitely aliens, wasn't it? Maybe...

And then, to make things even weirder...

The monolith suddenly showed up at the Petrodava Dacian Fortress in Romania. "We have started looking into the strange appearance of the monolith," said Neamt Culture and Heritage official Rocsana Josanu.

"It is on private property, but we still don't know who the monolith's owner is yet. It is in a protected area on an archaeological site."

What does it all mean?

And then, just when you thought there couldn't be more twists in the tale, a couple came forward claiming that they witnessed the monolith being escorted away.

In a lengthy Instagram post, monolith-hunter, Riccardo Marino, wrote: "All that was left in its place was a message written in the dirt that said 'bye b***h' with a fresh pee stain right next to it."

"Someone had just stolen the statue, and we were the first to arrive at the scene."

"We arrived at the location to see nothing but the foul markings left and we realized we must have been the first people to see it removed."

And even weirder?

"At about 10:45pm roughly 4 miles into Lockhart Basin we passed a truck that was hauling a large object strapped down In the bed with the hatch open. I thought for a second that it was the monolith but after driving 8 hours to get here we ignored it and convinced ourselves they were hauling off-road vehicles. We continued 30 minutes down the bumpy dirt road and arrived at 11:11 pm to the pinpoint I selected for us to start hiking from."

"Unsurprisingly there were other campers in the area that all seemed to be asleep. Right before leaving the car we heard voices in the distance, they were coming from the trucks we had just passed."

"We didn’t acknowledge them and continued minding our own business. Our short hike under the moonlight was easy to navigate by just using google maps."

"We made the best of the situation and created a more fitting exit for this otherworldly piece of artwork. Our rendition of the monolith returning back to space. Sadly some rando’s now posses it instead of our alien friends."

"On our way out we discovered fresh tire tracks that were made by a dolly, clearly left by someone not to long before us. When we got back to the car we drove back the way we came from and noticed the trucks where the noise was coming from were all gone. We figured it was the rest of the posse of monolith thieves exiting later than the first truck. Transporting the monolith without a posse in the dark had to have been a group effort. Not to mention it was 20 degrees Fahrenheit. We wanted to be the first to report this so we drove 2 hours back to service to get a post out. I’ll be posting more so be sure to follow and check back in."

And if you thought you'd seen the last of mystery monoliths...

Think again!

A shiny metal monolith was discovered near an ancient site in Romania recently.

And it has disappeared once again.

Many think thought that it could be the same monolith from Utah reappearing in Romania.

But the metal object has vanished for a second time.

A Romanian journalist called Robert Iosub confirmed that the monolith was missing.

"The 2.8 metre (9ft) tall structure disappeared overnight as quietly as it was erected last week," he told Reuters.

There were, however, some notable differences between the Romanian structure and the one that was discovered in Utah.

One being that the craftmanship seems less slick and seamless compared to the one in Utah.

Iosub went on to explain that there is apparently a local theory behind the monolith.

Explaining that local reporters had said: "An unidentified person, apparently a bad local welder, made it... Now all that remains is just a small hole covered by rocky soil." So, there you have it. Either way, it's certainly weird!
