Fungi: "No where on earth does a complete stratigraphic column like that exist."

nevermorelenore: "Mount St Helen’s is a great demonstration of geological features produced in hours and days, contrary to what was previously thought to take millions or years..."

I'd think Grand Canyon stratigraphy could serve as a reasonable approximation.
As for Mount St. Helens, such features in no way resemble those formed over many millions of years.
Any geologist could tell the difference.

Of course, anti-scientists can always figure out ways to confuse one for the other, right?

Yes, the Grand Canyon is an excellent example, despite a few gaps. At the base are rocks over 2 billion years old (that's still less than half the age of the Earth, approximated at 4.6 billion). And at the top, at least in the area depicted in your graphic, are rocks of Mesozoic age (~250 million years ago to about 66 million years ago. ie, the time of the dinosaurs). Don't know if there are any younger deposits than that at the GC, but I'm sure there are.

Because it is impossible to have a continuous, non-interrupted series of sedimentary (or igneous) rock layers. Earth just doesn't work that way. Sedimentary layers are the result of sedimentary particles washed off of mountains or some other form of highlands, and once the elevated regions are erosionally reduced to a flat surface, sedimentary deposition, for the most, ends, and the sedimentary beds themselves begin to undergo the slow process of erosion.

It's a similar situation with igneous or ancient lava flows. Once the source is depleted, that's it. No more deposition.
