Yellowstone Supervolcano Larger Than Previously Thought

[Ben]

New seismic surveys put it at around 14 times the size of the Grand Canyon.

Interesting perspective on size: If you piled all the humans that ever live in the history of the world into the Grand Canyon, they would not fill it.

I thought they figured out years ago that ALL of Yellowstone is the Caldera.  Which might help better explain the rich soils of the mid-west better then the "Glaciers pushed the dirt down from Canada."

First it was the fast food joints.  Then the sit-down restaurants (except the haute cuisine kind).  Now University of Utah scientists are supersizing the Yellowstone caldera.

Will there be no end to this?

stay safe.

Yellowstone = 3500 sq miles, Grand Canyon = 1900 sq miles. 1900*14=26,600 sq miles. Plus then the whole three dimensions thing. :)

Rich soils of Iowa and eastern Illinois is from the Peoria Loess deposition. That happened about 23,000 BP.

The ash from the last "Yellowstone" eruption would have been buried by the till of the Pre-Illinois glacier.

640,000 BP on Lava Creek eruption vs 300,000 retreat of the Pre Illinois glaciers. Any ash that wasn't buried by till would have been part of the pre Illinois inter glacial soils of the Yarmouth-Sangamon paleosoils. Those soils have been buried by post Illinois glacier/Wisconsin glacier and Peoria Loess.

Glaciers don't normally bulldoze, they absorb material and redeposit at the head. Think of a icy conveyor belt. When they retreat is when deposition occurs.

Came across this this morning

viewing now. The guy needs to slow down a bit, I know enough about geology to be dangerous.

Well, that's *expletive deleted*ing depressing.

But it would be a damned good start and getting rid of humans and turning the planet over to dogs.

23,000 British Petroleum?

Yeah, I know I'm commenting on something posted nearly a decade ago.

So wot?

"BP"
https://www.thoughtco.com/bp-how-do-archaeologists-count-backward-170250

I got trapped into going through this thread and wondered about that.  I guess "BP" avoids  "AD" and "BC" and "CE" (Christian Era) and Julian Dates, etc, but seems like it would avoid confusion if a writer just said "years ago." 

It's just another SAUONA (Smart Assed Use Of Needless Acronyms)  which demonstrates laziness and is evidence of a childish "I know something you don't know, nyah-nyah!" mentality, or a slavish copying of a military style.

Or all three.

Communication, after all, is the goal of writing.

Even "minus 23ka" would have been better, and better recognized.  Everybody knows what "ka" means, right?

Terry  said that and he ain't takin' it back.

PS.  I thought it was recommended somewhere, rather than bumping old threads to make additional comments, it was better to start a new thread quoting the relevant parts one is commenting upon.  Can't find it, and it may be a rule from another board, but it sure makes sense.

Saying 23,000 BP makes you sound more "educated" than saying 23,000 years ago.

Exactly.  My point.  "Showing off."  At root: "I know something you don't know, nyah-nyah!"

Terry said that and he ain't takin' that back, either.

I have seen "ka," for "thousand annums" which at least makes sense from a scientific nomenclature standpoint. But to me it's as awkward as saying kiloseconds.

"BCE" for "Before Christian Era"  just seems like a tawdry excuse for avoiding acknowledgement of Christ's real existence.  Kinda like Xmas.  But I was never sure whether Xmas honored Christ or not.  Sorta like JFK or HST or AOC (yuch), which are honorific forms of identification.

Count time from the zero point of the Unix epoch, and give it to them in gigaseconds.

[230RN]

^ LOL  You'd need giganumbers for the exponent. Just happened to note, after another cuppa, that a kilosecond is about a quarter hour.  Damned calculators.  D'ja ever notice whenever one's in sight, you have to pick it up and play with it?

"Before Common Era" is just a work-around for "Before Christian Era."

[Hawkmoon]

Well, since you asked ... why, no, I have never noticed that nor have I ever encountered anyone who seemed to be so afflicted. 

[Northwoods]

Even attention whores like NdGT still use AD and BC because he wants to honor the priests that devised the Gregorian calendar, despite the militant atheists (of which he otherwise is one) trying to berate him into using CE and BCE.
