Take the tour to find out ;)
Inner Space Cavern (Also known as Laubach Cave) is a karst cave located in Georgetown, Texas. The cavern was formed by water passing through Edwards limestone. The cavern is estimated to be around 20-25 million years old but were only open to the surface since the late Pleistocene period 14,000–45,000 years ago.
Hi, Drew! Our cave was formed by a fissure off of the Balcones Fault Line that was active about 20 million years ago. As water and air came into the cave, it carved out the rooms and created our formations. If you take our Adventure Tour, you can see the fault line and see where and how the cave started forming! Thanks for your question!
If you can take the basic tour, the story about how the cavern was discovered and where you are underground during your tour is fascinating! (I don't want to spoil it for you before you go. )
It was formed naturally by the dissolution of limestone 20,000-40,000 years ago.
