Thanks for that. Notice that line runs from Yellowstone to Mono Lake, the site of another enormous prehistoric supervolcano. I hope these supervolcanos are things that give off little tell-tale signs for a thousand years before they blow. And even then I don't know how N. America could possibly get ready for something like that. They're too darned devastating.

Too true.

I'd still rather know, than not know.
