As an Honors Geology student and recent holiday inn express guest I have to say this is BS. I particularly like the bit about the super-flammable rocks. Whatever. They also keep talking about this huge "20 mile wide deadly caldera". Well, there isn’t one there, PERIOD. A caldera is a circular depression CAUSED by an explosive volcanic eruption. How would a volcanic crater which was caused by an explosion which has is 20 miles wide and has somehow been missed by the millions of visitors to Yellowstone every year hurt anyone? I also like the news flash about how the tectonic system in CA is linked to the east coast and the rest of the world. Yeah, that’s called basic tectonic theory. I stopped listening when they started on about how Jesus told them this would happen. Don't waste your time Dloading this nonsense, should probably be deleted for lack of relevancy.
