I don't know what caused the hole.
But I'm sure the British Police can be trusted to uncover the truth about this mystery.
The British Police have been informed and are now on the case.
At present they're looking into it 🤣
Sorry!
That would be my guess... ongoing smoke billowing... sounds like the story about a new volcano in Mexico which started with smoke coming out of a cornfield hole. Over the next months or so... a full blown volcano pushed up and erupted.
@purplepoppy it could be a Wormhole, as predicted by Einstein.
It could connect distant points in time and space.
Wales one side of the hill, and who knows where on the other side of the hill. 🤣
Has anyone ever sampled the composition of the smoke? I'm sure that would clear up the mystery. Is it from burning coal or methane?
I'm guessing it is a collapsed mine. But it could be a natural geological phenomenon.
Oh, come on. Everyone knows the ole "Hole-in-the-hill Pub-n-Grill" . All the Hobbits drink there!
It's a sinkhole, perhaps cause by natural erosion.
The mysterious "Devil's Bumhole" has captured imaginations, and theories abound. The most plausible explanation is that it may be a collapsed mine or natural geological feature. The smoke-like effect could be mist or dust caught by the wind. While the missile and Mordor theories are entertaining, they lack evidence. It's always fascinating to see how legends and nature intertwine to create such an intriguing spot! 🏔️🔍
lol! But I just don't understand how the Mordor theory could lack evidence, Amy?

This is the Old Man of the Mountain. He also has a butt hole/

He does not! And it also collapsed in 2003. I never got to see it but my oldest sister did 'cuz she's a little goody-two-shoes, suck up , daddy's girl and got to go on a trip with him when none of the rest of us did and the rest of us still resent her to this day for it.
@RandomGirl42 I saw it on my honeymoon. I was it thorough the telescope tht was set up there. I was sad when his face fell off. I thought it was funny when New Hampshire wanted to make a fiberglass replica there so they would not lose the tourism dollars.
Definitely not the ass end of the UK. If you want to see one of those, visit any US "Southern State" to see our national anus.
It's the vagina of the world. Tie a rope around my waist, I'm going in
Looks like a medieval stone quarry to me, but I really hope is a dragon's lair. 🦖
Or maybe it's Nessie's home. Too many tourists at Loch Ness, she had to move.
I would guess a natural sinkhole even though I voted for a mine. It looks huge. Perhaps some smaller caves within it.
Clearly it is an underground mine fire much like exist in Pennsylvania, USA.
Eventually it will burn the entire country and sink it into the ocean.
I'm sure that be where the dragons hide. It's obvious from the smoke.
Must be a dragon nest, someone should call Daenerys.
I would say its just a photo with a hole in it. Whats the correct answer?
Looks like a shadow to me.
That's how the Earth farts
Is this even real, i think that it's A. I
No it's actually real
It's a natural formation i guess, a cave or something like a sink hole, nothing supernatural about it...
I think it's an old mine that collapsed
Cave entrance or collapsed mine?
Volcanic activity?
Ok - NO. That big black “hole” high above Abergynolwyn is essentially a natural (or partly modified) depression in the hillside which looks dramatically dark thanks to the sun’s angle and the bowl shape of the land. The “smoke” is not real smoke but either mist/low cloud drifting in the hollow or simply the shifting of shadowed terrain giving the illusion of smoke.
