Also the one where the evidence of prior catastrophic eruptions is all over the place. They blew a path through a mountain range in Idaho.

Yeah, the one that nobody ever saw erupting.
The Yellowstone supervolcano first erupted 2.1M years ago, followed by one 1.6M years past, with the last occurring 640,000 years ago.
It doesn’t take a mathematical genius to calculate that another is likely sometime in the next few hunded thousand years. When it goes, it will wipe out much of the US.

So is your contention it never happened, or it can’t happen?

That is, the hotspot beneath Yellowstone moved through Idaho. Actually, the spot is more or less stationary. It’s the North American continental plate that’s doing the moving.
Nobody saw Krakatoa erupt either. Well, nobody that LIVED. . .
