Skip to comments.A possible impact crater for the 1908 Tunguska Event
Posted on 06/22/2007 11:46:00 AM PDT by Mike Darancette
The so-called Tunguska Event refers to a major explosion that occurred on 30 June 1908 in the Tunguska region of Siberia, causing the destruction of over 2000 km2 of taiga, globally detected pressure and seismic waves, and bright luminescence in the night skies of Europe and Central Asia, combined with other unusual phenomena. The Tunguska Event may be related to the impact with the Earth of a cosmic body that exploded about 510 km above ground, releasing in the atmosphere 1015 Mton of energy. Fragments of the impacting body have never been found, and its nature (comet or asteroid) is still a matter of debate. We report results from the investigation of Lake Cheko, located 8 km NNW of the inferred explosion epicenter. Its funnel-like bottom morphology and the structure of its sedimentary deposits, revealed by acoustic imagery and direct sampling, all suggest that the lake fills an impact crater. Lake Cheko may have formed due to a secondary impact onto alluvial swampy ground; the size and shape of the crater may have been affected by the nature of the ground and by impact-related melting and degassing of a permafrost layer. -snip-

Aha! Now we know where the Golgafrinchians landed.
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.

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.
a huge kinetic bomb of explosive adiposity..
...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."
Not a lot of progress in that discipline. If they can link it to Global Warming they might electrically attract Algore.
now that is sicko
This is just a layman’s notion, but if the Tunguska projectile were a comet consisting mainly of frozen water, could the explosion that occurred be the result of air friction bringing that mass of water to a sudden, violent boil?
Actually scientific belief at the moment is it was a stony asteroid that exploded in midair, not a comet.
Beautiful, once you realize you’re zooming in on ice, not cloud cover...but about 20 degrees too far north for my tastes.
And also about 180 degrees wrong both politically & longitudinally.
