Did You Know There Were 3 Ancient Volcanoes in Missouri?
When I think of Missouri (and I do often actually), I think of a lot of things. Fishing, canoeing, Mark Twain and volcanoes. Oh, wait. I never think of Missouri and volcanoes, but apparently I should since I've now learned there were no less than 3 ancient volcanoes in the Show Me State.
