Catastrophism & GGG Ping.
Why would a comet suddenly “explode” just before impact?
further, why would a comet choose to “explode” and leave a layer of soot across N America like one would expect with a full eruption of Yellowstone?
just asking, LOL
Causing genetic bottleneck?
Hmmm, comet debris over Eastern Canada...space microbes evolve into...Quebec?
Did comet start deadly cold snap?

I knew you would post this. Look forward to the comments. Can you put me on your C&GGG pinglist?
I always associated the iridium layer with the punctuated equilibrium theory (Alvarez?) that stated the earth goes through some sort of asteroid complex about every 90 million years (relax, we are in the middle of a cycle) which leads to a catastrophic extinction of a lot of species.
People advocating a celestial origin for the Carolina Bays still need to answer two questions: 1) If the bays were formed in an impact event, why is there no deformation or fracturing of the soil layers below the bottom of the bays? The geology underlying the indentations shows no deformation at all, suggesting that the bays were deposited, dug, or eroded through some mechanism. 2) Why do core samples of the bays indicate wildly different ages for the indentations? According the sedimentary core samples taken from the bays, they were formed over a span of at least 30,000 years, and possibly more.
No celestial explanation can satisfy those issues. Personally, I’ve always thought they looked like thaw-basin ponds myself. Open Google Earth and look at the lakes south of Barrow Alaska. They are NOT hexagonal. Extremely wet marshland will form a hexagonal pattern because the “ponds” all durectly contact each other and it’s an efficient pattern for sharing stress as the ice expands in each. In the flatter and slightly drier plains, the result is an oriented series of shallow oval shaped ponds, with their direction selected by the prevailing wind. Warm these ponds up, cover them in a swampy forest, and you end up with a spitting image of the Carolina Bays.

It would be fascinating to see the location of these 26 sites, and the possibility of a "pattern".
Having read extensively about the Sudbury crater, Ontario Canada, made me wonder if it is only one of hundreds of impacts and/or explosions that occurred over a very brief period of time, spraying North America with evidence.
So many theories, so little proof. So this is why the flash-frozen mammoths have fresh grass in their stomachs?
I have been watching a 5 part series called ~North American Comet Catastrophe 10,900 BC over on youtube this morning. Firestone and West are on the panel, really interesting viewing.
