Carlsbad Caverns National Monument

From the National Park Service:
"High ancient sea ledges, deep rocky canyons, flowering cactus and desert wildlife - treasures above the ground in the Chihuahuan Desert. Hidden beneath the surface are more than 119 known caves - all formed when sulfuric acid dissolved the surrounding limestone leaving behind caverns of all sizes."
