Innerspace Caverns is a tourist trap in Georgetown, Texas - about 20 miles north of Austin. These caverns, the formation of which began ninety million years ago according to geologists, were discovered by a team of core drillers from the Texas Department of Transportation in 1963. Exploration resulted in the discovery not only of magnificent rock formations, but also many forms of life, most of them animals that have long been extinct.

The natural, pitch-black darkness of the underground isn't a prime environment for photography (nor adventuring!), so luckily the sights can be enjoyed with nice, ambient lighting. This shot was the result of said lighting, sans flash. I found this formation particularly intriguing, with an almost human quality because of its shape and smooth texture. I felt there was a nice contrast with the surrounding formations, as they were more rough and jagged than the subject of this photograph.
