Ok give me a minute. I think this really can illustrate a point in regard to the age of things and petrification and fossilization of wood, wood buildings too of course. And now I do wonder what the effect would be on concrete or hard stone structures. Maybe all we have to do is look at "rock cut" remains of buildings, or you know "tombs" carved into volcanic tuff and all the other megalithic oddities all over the freakin' place.
so anyway after you look at this and ponder it, just imagine how many cities or civilizations could theoretically be buried under us.
So back to Yellowstone and it's petrified trees. Yellowstone’s petrified trees occur within volcanic rocks approximately 50 million years old. They are the result of rapid burial and silicification, not volcanic eruptions per say, but the result of volcanic debris flows. Do we all know that Yellowstone is high, about 9,000 feet. I've been there it's like no other place I've ever been! Wonder what the elevation was for the first eruption, that's quite a debris flow. And apparently it has happened a lot in the last 50 million years. Or however long this all took or didn't take, it's a crap shoot on the dates I think.
