Look at a top down map of the Northern glaciers during the last ice age. Do you notice anything strange?
It looks to me like the glaciers are kind of lopsided. Definitely not centered on the Pole. Siberia and Alaska look like they were
And we can't know how far the ice extended out into the ocean. It's only possible to definitively say with certainty where glaciers left
their footprint on land (and where they didn't.)
So... I'm curious: what archaeological law forbids us to simply take these maps at face value, and assume the North pole was simply not located
where it is today? Why would it not simply be where the poles always are: right in the smack middle of all the ice?
If we need an explanation for a pole shift, there's a growing likelihood that Northern Greenland got hit with a very large meteor (11 to 12 billion
ton, 0.75 mile wide) sometime in the last 100,000 years, with the Younger Dryas event ~13,000 years ago being a likely candidate for that.
Alone, the meteor wouldn't be big enough to move anything probably. Because although 11 billion tons, or 11 trillion kg is a lot, the Earth's mass
is about 6 trillion trillion kg. (Yes, I said "trillion" twice. It's a 6 with 24 zeros after it.) Not even a comparison.
However, there is always a very small wobble in the Earth's axis of rotation. The Chandler Wobble. It's very small, but it goes to show the
axis isn't as stable as we might like to think.
Probably a lot of ice would have melted very suddenly, which adds to the mass displacement. The water would take some time to redistribute,
like probably a good share of a day at least.
For example, the Tsunami that caused the Fukushima disaster in Japan was estimated to take between 10 and 30 minutes to traverse the 67 kilometers
from where it originated, to the coast of Japan.
So a giant swell, flow, or tidal wave on the scale of the Haiawatha impact could take a good while to get completely smoothed out.
On the grand scale, it wouldn't change astronomy much. The North star would still be located at the new North. (I think it was Draco back then.)
Even the 12 signs of the Zodiac remain the same once you adjusted for the new orientations. The reason being because the Moon still
orbits at the same off angle it always has, forcing the rotation to resume being oriented to it.
The best way to visualize would be to take a ball and set it on top of water. Then start it spinning. If you just tap it, you find it really
doesn't take much to change the orientation of its spin. Like if you mark in black where the axis was originally (like what axis you
chose to spin it on). You might find the axis it ends up on after you perturb it is another one entirely.
