We've hiked at Copper Falls State Park - a beautiful place!
Last summer DD and I were in the Finger Lakes region of NY. "It's not fair!" she said. "They have thousands of waterfalls and Minnesota has about 5."
There were indeed waterfalls absolutely everywhere. It was beautiful.
Minnesota has enough for a whole book, apparently, but I suspect that many of those are more like water-stumbles than waterfalls.
