I also think the excursion was responsible for creating the Carolina Bays, the millions – yes, millions! – of huge elliptical depressions gouged into the ground at the same time. Many of those depressions were bigger than some modern-day cities.

Any Connection Between the Gothenburg Excursion and the Layer of Black Ash Around the World?
It is interesting that the Gothenburg Event of about 12,500 years ago seems to have occurred at about the same time, or perhaps 300 years after, the Younger Dryas Impact event. Evidence of the latter continues to pile up, despite continuing resistance by the scientific establishment, of a devastating break-up of comet tail debris around 12,800 years ago, which mostly rained down on and melted much of the 1 to 2-mile thick Laurentide Ice Sheet that covered eastern Canada at the time, with a large but lesser impact on the ice sheet that covered western Canada.
Above that black ash layer around the world, most of the megafauna that existed up till the firestorm and ensuing deluge ceased to appear in the fossil record — mammoths, short-faced bears, giant sloths, saber-tooths, etc. Much like like the way dinosaurs suddenly disappeared from sediments above the K-T boundary layer 65 million years ago.
Many of the megafauna were still thriving, like the mammoths, right up to that point in time when the black layer was laid down around the world, when most of the world’s biomass was burned. Also, interestingly, there are indications that the geological north pole may have been quite a bit further south before the Impact event, somewhere in northern Canada, since we know that Siberia had a much warmer climate at the time, with vast herds of mammoths grazing in Siberia, who were all suddenly flash frozen before their meat could spoil, or before some could finish digesting the buttercup flowers they had eaten hours earlier.
The Siberian climate has remained bitterly cold after that event until thawing of the permafrost about a century ago exposed these killing fields of countless numbers of mammoths that apparently died en masse, and the instant drop in temperature, and perhaps change in the earth’s axis or crust movement pushed Siberia into a frigid northern zone, freezing their huge carcasses in place in temperatures so low and so quickly that the meat and stomach contents didn’t spoil.
What I wonder is whether there might have been any connection between the Younger Dryas Impact and the Gothenburg event, though it is hard to see how the comet impact could have triggered the magnetic reversal 300 years later, if the dating for both events is accurate.
Perhaps it was just the planet’s bad luck to have two such catastrophes in such a short period, wiping out most of the megafauna in North America, and the entire Native American Clovis Culture at the same time. Notably, Africa was largely spared, with relatively few large mammals there going extinct, since it seems not to have been hit by much, if any, of the comet debris.
Note from Robert: Yes, I think the Gothenburg excursion is directly linked to the black ash layer around the world, and I think they happened simultaneously. But I have strong doubts of a comet impact. Scientists love to blame comets when they can’t figure out what happened.
I also think the magnetic excursion was responsible for creating the Carolina Bays, the millions – yes, millions! – of huge elliptical depressions gouged into the ground at the same time. Many of those depressions were bigger than some modern-day cities.
