You can't see them very well, but they do exist in Nebraska.

And the thing that I really want to show is that we go down to Georgia.

Now, that's a Carolina Bay, too, but it's not really pointing west.

It's kind of pointing north.

And if you go really far south...

this is one of the southernmost one that I could find, Arabia Bay Swamp, you can see one, two, three, I think four of these circular, and they're kind of ovals that are pointing direct north-south.

The thing about all of these bays, they've done studies on these, is that the bays are all pointing in a similar, to a particular point.

And they're pointing to a point in Saginaw Bay,

up in Michigan, but at the time, Saginaw Bay was covered in glaciers and it's covered in ice.

And that is where you used to have what's called the North Laurentian Ice Sheet, which is miles of ice going up.

And the idea is that an asteroid hits the North Laurentian Ice Sheet

and then it sends icebergs the size of stadiums raining down all along the eastern United States, creating these enormous craters, and then they melt away and they go away.

Now, if an asteroid hits from space,

It's going so fast that it's not going to hit like a divot.

It's going to hit the ground and then it's going to explode.

And so it's going to create a circular crater, no matter what direction it comes from.

Because these are all ovals, they're not from space.

They're from somewhere on the earth.

Now they're going to get thrown miles up into the air, thrown a thousand miles, and then they're going to rain down on that part of the land, but they're not from space.

It's a terrifying idea.
