This is Ashley, standing in the entrance/exit to Plunge Pool, which is a smallish cavern that is pitch black at night. By day, if you stand in there for a few minutes, your eyes adjust, and you can see a little bit of light that comes from a skylight 30 feet up.
I am an awkward, stubborn, slightly insane woman who would rather talk Plato than Prada, rather watch Frank Capra than Carrie Bradshaw, and rather listen to Norse myths sung in Icelandic than anything currently on the radio. Yeah. Told you I was weird.
