So it turns out Yellowstone National Park is riding on a big chamber of molten magma that occasionally erupts in such a way that it covers most of the continental US with about a foot of ash and can result in the earth being covered in snow, the oceans cooling, and the earth entering a mini-ice age. It's not the biggest of its kind, but one of the most active.

The last super eruption was 640,000 years ago. It's amazing how contemplating stuff like that makes so many problems seem insignificant.

@Arjuna,
it might be the answer to global warming.

Also Yellowstone lake is in the caldera and it is trapping enough toxic gas to poison the residents of of three states depending on the prevailing weather patterns on the day it erupts.

@GoshisDead,

@Arjuna,
It's a good indication to that global warming isn't manmade, but due to vulcanic activity.

I wonder if it puts oil spills and the like into perspective...

It's overdue I think, but still very unlikely to go off in our lifetime, given the time scale.
