Apperantly it was blasted into the air from Yellowstone and came down north of Cody, upside down.
Now that was some blast.
A blast indeed!
In the southern hemisphere, geologists tell us that a massive tnsunami once rose up and hit the south east coast of Australia. It tore through what is now Sydney and all the coastal cities, and actually rose above the Blue Mountains and smashed up the other side, far inland. Unimaginable.
But if there are massive volcanic explosions in Yellowstone, or in the Pacific trough between Australia and New Zealand, one would see such things again. Or not see them - as one would be lying dead on the ground.
Also, the Holy Land is overdue for a good earthquake, so say the experts.
The geological history of Wyoming is astounding. While the Heart Mountain event appears to be more of a massive landslide than a blast, there have been plenty of Big Blasts in the state's past. For a great trip through that past read John McPhee's wonderful book: "Rising from the Plains."
