Stalactites hang tight to the ceiling. Stalagmites grow from the ground up as calcite from dripping water builds up. When the formations meet in the middle they become a column. I’ve heard how cave formations build every time I take a cave tour. Yet, I never tire of touring the underground beauty of a cave. Each one is different in its own way, with unique formations, history, and in the case of Fantastic Caverns in Springfield, Missouri, its mode of transportation.
