What is that?

THE PATOMSKIY CRATER

The mysterious crater - also known as the 'eagle's nest' - was discovered 65 years ago in Irkutsk, Siberia, by a Russian geologist.

The cone is 80 metres tall from the lowest point of its base and measures 150 metres wide.

It is thought to be just 250 years old, although estimates differ widely.

Scientists previously suggested it was a slagheap, but now think there were not enough people living in the area to create it.

Some people believe it was made by aliens.

Scientists threw out the idea that the mound was made as the result of a uranium ore explosion as the site has low background radiation.

They have floated the idea that it could have been made by a volcano, but none have been found nearby.

An impact made by a meteorite is the favourite theory but no evidence of fragments has been found.

It is thought there is something with a high iron content over 100metres below the crater, which could be a meteorite.

The crater is 'alive' and changes shape - by rising and falling - constantly.

Trees nearby the site are reported to grow abnormally fast.

I dunno... but somehow it reminds me of quite a number of so called "craters" on the moon, who look quite similar to my eyes and have reportedly also changed shapes throughout a fairly short period of time.

The last two points (bolded above) are also quite interesting.

Re: Scientists baffled.What created Siberia's 'Eagle's Nest'? A meteorite, vulcano?

Yowza! I would've assumed that it was a meteorite impact too, but I really don't know. A lack of fragments is significant (I'm always going to think "cover-up") for the meteor theory, & maybe something happened to them over time that lent itself to the rapid tree growth, which in turn, accounts for the changes of the "breathing" (rising & falling) effect? My first thought was "they removed the fragments (because the material was important & could leave big cosmological clues) to prevent independent research at a time when it'll most be needed - and left behind the mystery".

That is very, very big though & although I don't know enough of the sciences that could shed light on this, what I do know is that if it is 250 years old or so, then that date is already compromised; the recent developments in the Julius Caesar thread will attest to that. Imagine, we might have to re-revise all that anthropological, geological data & more...

This has been on another thread here or was it an article, don't remember...
But anyways the most significant thing to spot IMO is that it is a mound not a "dent" in the ground which an ordinary impact, of sorts, would produce.

Edit;
article on sott found here:

Looks to me like a pile that is made by an ant lion, almost. As if what is seen is the dump from digging underground.

Added: Read the article on sott where they finally propose a "gas volcano". Yeah, that would make sense.

 

[clerck de bonk]

I know this sounds silly, but IMO it looks like it is "bubbling" up from under the ground... Like a slowly oozing mud or asphalt volcano (only lithic!?) in this case.

Edit; @Laura, thats even better

Look at the close-up shots and you see a bunch of broken rock. That says "explosive force" to me.

This site also suggests a gas purge as being the most likely explanation. The English on the site doesn't all make sense. It has a couple of photos showing, (if they are authentic), that the site is not all just loose rock, but has some interesting formations in it.

In the first article, a possible connection to the tunguska event is mentioned:

Scientists thought the crater was only between 100 and 500 years old and could be the result of the Tunguska meteorite, which fell in the Krasnoyarsk region in 1908, but whose crater has never been discovered.

It is thought the meteorite was sighted just 70km away from the ‘eagle’s nest’ and that distance is a mere 10 to 15 seconds of flight.
As the Tunguska event occurred in 1908, the age coincides, but modern tests have shown that the crater is actually 250 years old – so it could have been formed by a previous meteorite that fell when the area was virtually unpopulated.

So if we can trust the age dating, then this"crater" was created well before the tunguska event.

If I remember correctly the Thunderbolts team proposed that some of the "double craters" on the moon, earth and other planets could have been created by rapid electrical discharge machining.

But that still makes the undgoing apparent rising and falling of that crater a bit difficult to explain.
Maybe it is really some kind of movement that is coming from the earth itself?

I dunno...

I agree,

if those are really authentic pictures from that "crater", it really looks like a mud or gas purge that is still ongoing in the underground, could be the explanation.

 

[clerck de bonk]

Yup, but it still doesn't completely explain the hole process to me.
Gas would release through cracks in the rock as soon as they emerged => IMO, no "lithic oozing" process possible.
If, on the other hand, the pressure would be higher than the cracks in the rock could let through, there would be an "explosive force" (which, evidently there have been) and a singular deep crater with widespread debris around would be the result.

They may not be authentic. The following 7 minute Russian video has a montage of shots of the "crater". Although they don't show every angle, it looks much more like a pile of loose rock, and I don't see that spherical formation anywhere in them. The section from 2:37 to 2:51 has some good close-up shots.

The fact that it's constantly rising and falling seems to point to volcanic type activity, but just for fun I looked for pictures of electrical discharge scarring and found these Thunderbolts articles:

Scroll down halfway on the last one to see the domed craters.

I suppose it could be possible...
