Rising Underground Waters At Inner Space Cavern

[Wayne Harrison]

Water is no stranger to Georgetown's Inner Space Cavern.

Even in the outset, long before the path reaches some of the lower levels, the ground was already covered with water.

Inner Space was carved out thousands of years ago by an underground river, cutting away at buried limestone.

"Watch your heads, the ceiling's low, and the floor is going to be slippery," said an Inner Space Cavern employee.

"Every time it rains, the water starts to seep down through the soil," said Inner Space tour guide Richard "Doc" Wills.

"Now, where does the water go whenever it comes down? Where does it end up at?" asked a visitor.

"It all is just trying to slowly drain down to the Edwards Aquifer," said Wills. "So that's where all this water in this cave is trying to go is to that aquifer."

As the water in the cave seeps down, the aquifer rises up to the cave.

"This occurs maybe once every five to 10 years, if we're lucky," said Wills. "So it makes the cave interesting."
