And since the North American plate is drifting across the site of the mantle plume, each of these earlier eruptions took place further to the west of the one that came after it. By traveling west from Yellowstone, you can track eruptions backward in time.

It's a great story, but it's only true up to a point, and that point is somewhere near the Washington-Idaho border. That's where the eruptions that form the Snake River Plain (which ends at Yellowstone) give out, and the High Laval Plains begin. When that happens, the age progression reverses: suddenly, as you move west, the volcanoes get younger. Confusing matters further, just to the north there are even older deposits where the magma bursts out of the Earth in floods rather than through volcanoes. There have been several competing explanations for this, but now some researchers claim to have sorted it all out. Their tool? A small vat full of sugar water.

Modeling the Yellowstone magma plume with a vat of sugar water


Interesting proposition, though I think it's a bit easy to read your own results into it due to no blinding.
