extropolating from this map which charts the location of 'ancient Yellowstones', the next event may happen up in Montana

Apparently the North American tectonic plate is sliding over a magma chamber, which explodes about every 650,000 years or so. Interesting. If an asteroid doesn't get us, our own planet might. It really is a dangerous world out there.

Interesting, it's like the Hawaiian hot spot (http://www.soest.hawaii.edu/GG/HCV/haw_formation.html), only on land.

I think the range was actually something like every 600,00 to 800,000 years and the last Yellowstone supervolcano eruption was at about 600,000 years ago... unless that's been updated recently.:)

I'd like to mention (this a good place) Bill Bryson's recent non-fict *A Short History of Nearly Everything* which (altho stingy on Biology as most such general popular works tend to be) is light, brisk, anecdotal, witty you could like it in-bed or in the bathroom/bathtub. He has a chapter on volcanoes w/ lots of specific info about Yellowstone Park. Life here is more precarious than you'ld (like to) think, Baby!

I apologize for & rescind my cavil, (immediately-foregoing post here), that Bryson's book (I said) is inadequate for the biologies. That statement of mine is not true.
I had read the first half of the book; and then scrutinized its INDEX, for such topics as *Koch's Postulates; Barbara McClintock; Burgess shale; .....* Altho it's quite long, Bryson's INDEX to this book is inadequate. The *text* however (of which I have since continued to read about half the remaining) is fairly-well representative of the subjects which (I believe) it shd include. For example, altho the Burgess shale matter is not in the INDEX, Bryson has written a good share of a chapter about that.
Hence I recommend this book to EyeEye participants who may want/need some general introduction to the sciences to bring them up to speed and to point them to further & more-detailed information. Like that old warhorse of the 1930s, which helped to turn me on to Biology, Wells-Huxley et als *The Science of Life*, this popularising work of Bryson's = *A Short History of Nearly Everything* is a good introduction for the uninitiate.

...and that ends today's demonstration on how to graciously revise your conclusions when new evidence presents itself.

Please, drop by often because, such occurrences are not scheduled.

I'm in the middle of that book right now Abe, it is filling in some spots for me. I knew about the yellowstone caldera for years but I was listening on the radio the other day about scientists recently discovering a large bulge under yellowstone lake that previously wasn't there.

Could pop any minute killing everyone within a thousand miles. :)

Nice to remember when getting stressed about something inconsequential like bills, etc.

*Gets out map. Finds distance to Yellowstone National Park. 460 miles!:eek: *

Well, that's nice to know.

There was just a show on the Discover Channel about Super Volcanoes, the last one to blow was 74,000 years ago in Sumatra, it nearly wiped out the human race. They traced Mitochondrial DNA and found a bottleneck at this point, there were only a few thousand hominids left after the long winters that followed. The last time Yellowstone blew (600,000 YA) it covered 1/3 of the US in 2 meters of ash. It had the power of 10,000 Mt. St. Helen’s blowing up. Look out!

any YEC's care to comment? i'm up for a few laughs...

why on earth does this look like the gradual progression of tetonic plates over millions of years?

;) Because god made it look like the earth was old to trick us. He's funny like that. Or is it Satan that does the tricking? I can never remember.

yeah, they just seem so similar don't they?

oh well, cool pic, i'm glad i'm on the other side of the earth though <g>

however we have our own lake taupo... an entire lake that was a crater... when it went off Japan saw it, and its estimated to have been the loudest sound ever to be heard on the face of the earth. THAT'S big.

“Because god made it look like the earth was old to trick us. He's funny like that. Or is it Satan that does the tricking? I can never remember.”

Maybe it isn’t a trick at all. Most movies, or novels for that matter, don’t start with the birth of the universe or even the birth of the main characters. The stage is set, the scenery and background information are in place etc. Let the show begin!
