Quit arguing. Yellowstone could never have had a supereruption caused by an orbital strike. The Yellowstone Caldera is several KILOMETERS thick, you'd have to break through all of that in order to cause a super eruption. Mjolnir is not that powerful. All an orbital strike on Yellowstone would do is maybe trigger a few hydrothermal explosions and perhaps a few lava flows and ash columns.
