My husband caught one of those shows on Discovery or History or one of those channels talking specifically about Yellowstone and the super-volcano underneath. The volcanic cauldron is something like 150 miles across and if it were to blow (which supposedly it's overdue for), they were showing conditions that would turn similar to like a nuclear winter and destroy at least 90% of life on earth. Scary to think about.
