Since eruptions are tens to hundreds of thousands of years apart, depending on the size, I'm not sure such short time periods of 20-30 years are meaningful.


Probably wonder how much uncontaminated drinking water will remain west of the Mississippi in 72 hours...

I'm not sure the a 20-30 year record is terribly meaningful either- I just don't know if we have good, 24/7 logs of the activity there that goes further back. If we do, GREAT! Let's throw that into our analysis.

I know our numbers are very short term no matter what, but you decide your actions based on the data you have at the time. *shrugs*

Ancient irish warriors of my matrinlinear family created the family crest of a guy on horseback riding through the surf to escape his enemies. The truth is found in other accounts of celtic warriors attacking enroaching seawater on horseback with drawn swords.
I figure, if I'm at Yellowstone and anything happens I'll just stand with my RSK in hand and tell the forces of nature to knock it off, eruptions not in the brochure from AAA.
Meanwhile, last night had a lovely porgramme on Yellowstone in winter, including the narrater spending the night in a blizzard with a -20 rated down bag and a tarp shelter. He woke up to his film crew asking how he did.His comment, interrupted by deafening winds, was on flapping of his tarp kept him awake.
He then observed John Coulter only had a buffalo robe and probably slept better.
I must practice making my tarp knots tighter to reduce flapping and increase resistance to volcanic ash.ROTSLOL

Aww Man!! Went and got my hopes up for nothing....
