    12,800 Years Ago, Earth Was Struck by a Disintegrating Comet, Setting Off Global Fire

    According to a massive research study, Earth was struck by a comet 12,800 years ago that caused massive wildfires to rage over 10% of its surface.

    . Based on this data, the team concluded that roughly 12,800 years ago, a global disaster was triggered when a comet measuring about 100 km (62 mi) in diameter exploded in our atmosphere and rained fragments down on the surface.
    That must have been one heck of a pre-impact comet show!

    That was the supposed impact that started the younger dryas period, ie extra cold end to the ice age, caused huge devastation, sea level rise of 300 feet, possibly the biblical flood, the most recent big impact.

    So they head the article with an illustration of a body at least 10 times that size striking the surface. Come on, UT, you need to do better than that.

    If the pre-impact fragmentation broke into 8 billion equal chunks (ignoring ablation) they would each be the impact size of the AZ crater. Is anyone suggesting an impact site? Wall art?? Or something?

    We know time flies, we just can't see its wings.

    125 billion Chelyabinsk chunks, but instead of putting a hole in the ice, this put ice in the hole. PDB (Pah-Dum-Bum ... on the drum)

    From previous evidence for that impact the principal site was in what is now Washington state, then under two miles of ice. I have not seen suggestion of minor sites apart from this recent study.

    Wasn't this ice much earlier for WA?

    Neat. Who lived on Earth in 10500bc? Were they story tellers and builders? This is no doubt the type of event that would be remembered and transmitted, and, I daresay, echoes the "lost civilization" hypotheses. Did Plato think he was recounting History or Myth?
    Where the telescope ends, the microscope begins. Which of the two has the greater view?

    Such an event could explain some of the mysteries about the history of people and megafauna in North America.

    My understanding is that this date is at about the same time as when the Clovis peoples disappeared, when their typical spear point designs were replaced by Folsom designs.
