And they laugh at us for living in a place where -20°C weather is toasty warm. At least we're not living on top of a giant, 250 mile deep bomb.
Well, except those of us in the Aleutians.
For those of you who didn't know, Yellowstone sits on top of a massive Caldera that's still active, geologically. It last erupted a few hundred thousand years ago, when it sent a few hundred square miles of material into the air, raining it down as far as the other side of the world. It's a big-un', as the cool kids say. Whether it goes soon (In the next 100,000 years) or not depends on whether now having the Rocky Mountains on top of it is enough to bottle it in, but when it goes it'll take out a chunk of Idaho, Utah, and Montana with it.
If Utah, Idaho and Montana still exist, when it explodes.
