In 1945, in Irkutsk Siberia, a geological discovery was made that still baffles scientists today: te Potamsky Crater, also sometimes called The Eagles Nest because of it's convex shape and round mound in the center
The current theory of the crater's strange shape is a meteorite strike, but if so, it's shape is unlike any other meteorite strike and no evidence has been found to otherwise support the theory.The crater's edge stands 80 meters tall and 150 meters wide. The depth around the mound in the center is 10 meters.
The crater was discovered by Vadim Kolpaknov and since then many expeditions have been made to sample the site, including one in 2013 but because of the remoteness of the area, there weren't enough people living in the area to remember how the crater could have come about.
Some other theories include that the crater was a gulag (though there were never any in the area) or that it was a slag heap (though, again, not enough people living nearby to create one.)
Which pretty much just leaves two thoughts: meteorite strike or volcano.
But the area is not a volcanic region which pretty much rules that out. Plus, scientists think the crater is relatively young: formed between 100 and 500 years ago.
It's possible the crater could have been a result of the Tunguska meteorite, which fell in the region in 1908 and whose crater was never found. But of all the numerous samples collected, none have been meteoric.
On top of that, scientists suspect there is something buried with a high iron content and ferromagnetic materials about 100-150 meters below the surface. Possibly a meteorite or another dense object.
And if all that isn't weird enough, let's put the cherry on top. The crater is considered to be "alive". That is, it's shape constantly changes by rising and falling. And, apparently nearby trees tend to grow abnormally fast.
Thoughts or theories?
