I've been trying to find some studies or reports about this mysterious crater. As Armap posted, it was discovered by V.V. Kolpakov, a
with a secondary interest in
, the accurate dating of rocks and sediments etc. The Patom Crater is named after
the Patom Plateau where it's located rather taking Kolpakov's name.
The story gets more interesting here. Many ATSers will be familiar with the Tunguska
but here's a brief outline...
In 1908 a meteor or possibly a NEO (Near Earth Object)
exploded in mid-air above the Tunguska forest area of
Siberia. The blast zone levelled an estimated 800 square miles and would have devastated any population center. The light from the explosion was
visible for hundreds of miles. An eyewitness from 40 miles away described how...
The split in the sky grew larger, and the entire Northern side was covered with fire. At that moment I became so hot that I couldn't bear it, as
if my shirt was on fire; from the northern side, where the fire was, came strong heat. I wanted to tear off my shirt and throw it down, but then the
sky shut closed, and a strong thump sounded, and I was thrown a few yards. I lost my senses for a moment, but then my wife ran out and led me to the
house. After that such noise came, as if rocks were falling or cannons were firing, the earth shook, and when I was on the ground, I pressed my head
down, fearing rocks would smash it. When the sky opened up, hot wind raced between the houses, like from cannons, which left traces in the ground like
pathways, and it damaged some crops. Later we saw that many windows were shattered, and in the barn a part of the iron lock snapped."
The devastation that the Tunguska impact caused can be compared on this map of London...
Until recently, it was thought that the Tunguska meteor was obliterated in mid-air and didn't create a crater. The epicenter of the flattened forest
doesn't feature a crater. An unusual lake near the blast is possibly a crater
still shows the damage from a hundred years ago...
This brings us back to Patom Crater. It has no comparisons to other craters on Earth and only shares similarities with some on Venus (see previous
posts) and the Moon. It's anomalous.
The Patom crater, in contrast to similar forms of relief known to science, is strikingly peculiar because it looks very much like a volcano but
contains no trace of erupted in-depth rock. It all consists of fragments and boulders (sometimes several meters thick) of local sedimentary rocks,
i.e. Precambrian limestone. The entire mountain is composed of the same limestone, and both inside and outside the crater the limestone contains no
trace of a change induced by hydrothermal or any other processes. Nor does the shape of that relief feature look like a classic blast-made meteorite
crater. It does not resemble a crater from which the rock was ejected by force of explosion.
The lack of forestation and established plant life on the Patom crater implies a date much earlier than 300 years. The article suggests that it may be
a secondary impactor from the Tunguska event. The date would be 1908.
Instead of one object exploding above Earth and leaving the flattened forest, it may be an object that broke up and made several impacts. The Patom
Crater is so extraordinary it needs an extraordinary explanation.
The writers speculate that it was a multiple body impact or a single body that broke up in the atmosphere on a low trajectory...

...the celestial body in question was made the mounted boulders of solid methane rather than solid hard iron or olivinite and they scattered loose
when it passed through the dense layers of the atmosphere flying 30 km high and some fragments dispensed as flying cassette elements fell out upon the
ground within the “zone” extended in the northern direction. If a meteorite flying at a space velocity penetrates the earth, thus creating a rock
grinding zone around itself (without a blast discharge) of about one million cubic meters, and if we apply the soil loosening factor for normal
explosion processes (1, 2), an increase in the volume of rock mass will amount to 200,000 cubic meters. Calculations have indicated that the depth of
such a zone should be over 200 m.
Instead of a material body colliding, it could be a more gaseous conglomeration traveling at vast speed (15-20 km.p.s) and striking the limestone
plateau. The result is the anomalous Patom Crater, distinct from all other meteor craters
. The gaseous body explodes beneath the limestone and leaves the indicative signs of a volcanic eruption without any of the evidence.
The limestone is shattered and displaced upwards. Lake Cheko
and the Patom Plateau should
be explored further to gain a better understanding of what happened at Tunguska and how the intriguingly formed Patom Crater came to be.
It's certainly mysterious and if it was located anywhere other than the middle of Russia (beyond my means), I'd be looking to travel there just to
