PNAS: Very High Temperature Impact Melt Products: Evidence for Cosmic Airbursts/Impacts at Younger Dryas

Well, well. A cat just leapt from the bag.

I don’t have an “as published” copy yet (despite being a co-author). But I will post one just as soon as I do.

See here for UCSB Press Release:  Study Jointly Led by UCSB Researcher Finds New Evidence Supporting Theory of Extraterrestrial Impact 

These scientists have identified three contemporaneous levels more than 12,000 years ago, on two continents yielding siliceous scoria-like objects (SLO’s),” said H. Richard Lane, program director of National Science Foundation’s Division of Earth Sciences, which funded the research.

“SLO’s are indicative of high-energy cosmic airbursts/impacts, bolstering the contention that these events induced the beginning of the Younger Dryas. That time was a major departure in biotic, human and climate history.

Cool video on the story from Slate:

LA Times Story

The cause of the Younger Dryas cooling period has been very controversial. Some researchers have proposed an extraterrestrial impact and have produced evidence of the event, but others claim that the results have not been replicated. The new findings, reported this week in the Proceedings of the National Academy of Sciences, appear to provide that needed replication. — Thomas H. Maugh II, LA Times

  • Congratulations George! Very respected journal; great paper & results. The evidence is growing that an event of coherent catastrophisim occurred at the YDB event. It seems clear that the CBs were not associated, but so what!

  • George Howard

    Not so fast, Mike. The South Carolina site was indeed a bay. I was surprised it produced the evidence it did, frankly. But it is what it is! I will send you a copy of a draft by email.

  • Any idea when we’ll be able to read the full paper?

  • George Howard

    Checking on that. It is kinda confusing — and there is no way i am posting anything that is a draft in any fashion.

  • George Howard

    Having read it, the paper lends a lot credence to Dennis Cox’ musings regarding a rock-based, molten, hell wind.

  • Hello George

    Yes, it’s nice to see the ideas and experiences converging to face facts that add up, and the various aspects of meteoritic phenomena. I learn something every day. Very good. Congratulations to all.

  • Thanks George,

    As an amateur who’s been working full time on an a new, and extremely radical theory of airburst geomorphology for more than three years now, I have to confess to intense satisfaction, and feeling extremely validated by the new papers coming out of the peer review pipeline that are almost perfectly consistent with my “crazy” thinking about cluster airbursts, and multiple impact zones.

    But if by some strange twist of fate it turns out that this amateur is right about the planetary scarring of very large cluster airburst storms in north America sometime around the end of the last ice age, I’m thinkin’ these new papers are only the cusp of a paradigm shift in the Earth sciences (especially in impact geomorphology) as profound as the realization that the world isn’t flat.

    Because in the geophysical world according to me, in the primary impact zones, and after only 12,900 years, most of the planetary scarring, and blast-effected materials of the single most violent impact related natural disaster in 65 million years is still in almost perfectly pristine condition on the surface. But those materials have long been assumed without question to be volcanogenic by uniformitarian geologists of the past who could never have imagined such heat, and violence coming out of the sky without making a crater.

  • What’s Up With That is running New evidence of extra-terrestrial impact too. With their wide readership, the article’s getting a lot of comments over there. Ya’ll might want to drop in, and have a say in it.
