The entrance to Black Chasm.
I didn't notice it at the time, but there's a centipede (or something similar) on this stalactite. This is just inside the entrance to the cave.
Many parts of the cave, like this area, still had lots of water seeping in from above.
This small section was covered in crystal formations.
A tree root from above dangles from the top of the cave.
The little twisty things are rare formations called helictites. This cave has some of the highest concentrations of them ever discovered.
They put a light behind this to show how thin the rock formation is.
Another cluster of tiny helictite formations.
Both of us in the cave. The spots on my shirt are from water dripping from above.
Most of the helictite strands are no thicker than a toothpick.
