Awe inspiring is the best way to describe a trip into the Inner Space Caverns near Round Rock, Texas. The publicly accessible tour of the cavern is about one half mile long, a great “smaller” cavern if there is a way to minimize the greatness of such an enormous sight.  An enthusiastic guide leads the group and tries to explain what is mind boggling, hundreds of thousands of years of dynamic rock, minerals, and water that have created and continue to perfect earth’s natural artwork. Each room is different from the next and where the light ends, your imagination begins to dream up what still lies beyond in the undiscovered darkness.
