“So much for that elk hunt I have been saving for.”
On the positive side, hopefully the ash cloud won’t make it to the middle of Iowa if it goes off.
On the other side; our record winter would probably continue for another 12 months all the way through 2010 and beyond.
If it really goes, then the ash will circle the earth and there will be crop failures all around the Northern Hemisphere.
If Jellystone blows the ash cloud will circle the planet in less than a week. Iowa will not be passed over. Oh and globull warming will be the least of our worries.
How far the ash cloud spreads, direction, depth depend on wind speed direction AND duration of the event. You’ve got at least 400 cubic kilometers of stuff to come out. A inch of two on your roof of the ash could be enough to make it colapse - snowing concrete.
