Missouri does have a dozen or so waterfalls, but some of them are about two foot.
I ran across this one last week, at Taum Sauk State Park, which is a beautful place in the Ozarks. But just about the whole of southwester Missour -- the real Ozarks -- is breathtakingly beautful.
Taum Sauk is more in central Missouri, really not that far from St. Louis (an ugly city that I left a long time ago). Maybe two hours.
