It is said that Crystal Cave Park is one of America's most beautiful caverns. Everyone has to decide this for himself, but a statistical fact is that crystals line 80% of the walls and ceiling of this cave. They are also called Speleothemdogtooth spar.

The cave also has Speleothempopcorn calcite and Speleothemboxwork, and of course some stalactites and stalagmites.
