The cave was first formed when the ground levels of water began to drop. As this downward movement occurred, the water began to dissolve the limestone. This downward drainage continued until great underground stream beds were cut out of solid rock. It is this unusual combination of dissolving and cutting by water that makes Longhorn Cavern one of the most unique caves of the world.
