A possible impact crater for the 1908 Tunguska Event

Looking at the picture I'm surprised that this was not hypothesized sooner.

Coooool.

” Lake Cheko may have formed due to a secondary impact onto alluvial swampy ground “

Aha! Now we know where the Golgafrinchians landed.

It has, one of the science channels did a show on it, they hypothesized about that lake and took samples from it years ago. I think the majority consensus was a comet made up of smaller stones and ice that exploded, causing a huge bang but not a lot of large debris laying around.

Catastrophism ping?

There was a Russian geologist who theorized something very close, believing that the remains of the asteroid or meteor broke up into several pieces, drove into the earth, and that permafrost etc melted enough to create swamps in an already swampy land. He was researching for several years, but volunteered when Germany invaded, and was captured and died in a prison camp.
Learned that on History channel, but i forget his name.

Oh well, I guess it has been there for almost 100 years. It'll still be there later.

Not so sure I’d recommend eating it, tho.

Thanks BJClinton for the ping.

There is growing evidence that electrical activity in the cosmos is more important than gravity in defining how bodies in space interact. The Tsunguska meteor/comet may well have accumulated enough charge in its route to Siberia to cause an electrical discharge (lightning bolt) immense enough to nearly vaporize the puppy, knock down a lot of trees and create a crater with discharge rilles, probably much closer to the ground than the 10 or so kilometers high that is usually quoted.

Why astronomers still refer to comets as “dirty snowballs” is beyond reason. It has been definitively shown via satellite photographs and impact experiments, that comets are very solid with almost zero water content. Orthodox astronomers invented the snowball canard in order to explain comet tails as the evaporation of ice, basically a steam trail.

Now that it is known that comets are in fact meteors, a new theory of comet tail propagation is necessary, one that includes electrical arcing and cratering of the meteor’s surface as its charge potential is changed while moving closer to the Sun’s and through the Sun’s electro-magnetic field.

First time I’ve hear this, and it may solve a long-time mystery. This should get more geological studies to the area funded.

"Cheko, a small lake located 8 km from the alleged epicentre of the 1908 Tunguska Event, has an unusual funnel-like bottom morphology, with ~50 m maximum water-depth near the center and a 0.16 depth-to-diameter ratio.

...A prominent reflector observed in seismic reflection profiles ~10 m below the bottom at the center of the lake indicates a sharp density/velocity contrast, compatible with either the presence of a fragment of the body, or of material compacted by the impact. Drilling could solve this dilemma."

Nice summary.
