Inner Space Caverns

Inner Space Cavern was discovered by a Texas Highway Department core drilling team in the Spring of 1963. While drilling through 40 feet of solid limestone, the bit broke into what is now known as Inner Space Cavern. An adventurous employee of the highway department was lowered into the hole while standing on the drill bit and holding tightly to the stem. He was the first human being to enter INNER SPACE. What an exciting voyage this must have been!
