This summer, my dad and I visited Carlsbad Caverns. That place is the physical manifestation of cavernous: Cathedral-like ceilings, “bottomless” pits, and rooms the size of city parks. Stalactites and stalagmites decorate these caverns like statues in a museum. Stalagmites (the ones on the ground) are towers that formed one calcium droplet at a time. The plunk, plunk, plunk of the droplets echoed through the caverns—slowly sculpting stalagmites for thousands of years. This commitment was nothing short of awesome. It inspired me: If little droplets could create giant sculptures, why can’t a person write a book?
