Have you ever looked at a topo map of the northwestern quad of the US and seen the burn path that hotspot has cooked across the county? Incredible. Mt. Mazama was nothing compared to the event that eventually will happen in Yellowstone.

Yeah.
It's had at least two good blowouts in two opposite directions, and there's a smaller caldera next to it that blew out at one point as well.
There's a website somewhere about supervolcanos
I don't have it bookmarked, like a dunce, but it was an interesting read.
