Halloween Week Feature: Inner Space Caverns in Georgetown, Texas

Since its Halloween week, we thought we’d feature the unique client Inner Space Caverns in Georgetown, Texas. We are fortunate to produce the patches that they sell to tour participant in their gift shop.

A little background: Inner Space Cavern was discovered by a Texas Highway Department core drilling team in the Spring of 1963. Six-inch core samples were taken to determine if the ground was stable enough to support a large highway overpass. As they were drilling one of the test holes, the bit suddenly dropped 26ft. and the highway crew knew there was something down there besides rock.

Hidden for over 10,000 years, Inner Space Cavern is one of the best preserved caves in Texas. Inner Space was opened to the public in the summer of 1966, and since that time hundreds of thousands of visitors have seen this beautiful cave.

We caught up with one of the many tour guides at Inner Space Cavern in Georgetown, Texas to ask a few questions about the natural attraction.

innerspacecavernPS: What makes the caverns unique?
ISC: The cavern are unique for a lot of reasons, but I’ll give ou a couple of my favorite highlights:

There were 5 entrances to the cave in recent history. On the tour we refer to these as
“Bone Sinks’ which are sinkholes that we found bones in. When the rooms of a cave became so large that the roof could no longer support its own weight, it would collapse. This allowed animals to enter. Which is how we found fossils of at least 44 different species of animals, 11 of which are now extinct.

There is a room in the caves call the Cathedral Room. It is the largest room in the cave.  Some of the fossils are still quite soft, which makes it very difficult to remove them without doing damage. Some of the bones were left where they were found in order to preserve them.

Lastly, the oldest rock in the cave is roughly 100 million years old. The void of the cave was forming when the Balcones Fault Zone was active about 25 million years ago. This is the closest we will get to knowing the caves age.

PS: Are there bats?

ISC: Yes. The types of bats we see most are the Eastern Pipistrelle, which is also known as the butterfly bat. They are the second smallest species of bat in the US.


PS: Do you do any special Halloween events in the caves?

ISC: We don’t usually. But we do see an influx in visitors around that time, most likely because the mystery and darkness of the caverns ties in closely with the Halloween season. It is a fun activity for this time of the year.

PS: How many visitors do you see at the Cavern each year on average?

ISC: We see a lot of school groups throughout the year. We can average 15-20 groups during our busy days.

PS: Do you notice anything changing in the caverns over the years?

ISC: We do our best to preserve the cave and protect the bats etc. Although, it’s hard to deny the bat population has diminished.

PS: What do you want people to know about the Caverns?

ISC: That it’s a great place to visit and bring your family. Although Texas can get very hot in the summer, the cavern are a great place to visit year round as it’s usually pretty cool down here on the hot Texas days.

unnamed PS: And lastly, how do you use the products you order through us at Inner Space Caverns?

ISC: The patch we have is a hot item in our gift shop. I’ve seen students put it on their backpacks, they love it!
