Did you know that in Tennessee, you can tour the largest underground lake in America? 👀 Hidden deep inside a mountain near Sweetwater is The Lost Sea. The cave has been explored for centuries, even showing footprints from a giant prehistoric jaguar 🐆 But the underground lake itself wasn’t fully discovered until less than a hundred years ago, and scientists still don’t know where the water comes from or where it goes. It sits about 140 feet underground, and once you reach it, you’ll take a boat
