Descent

Here's a photo of Peter and I. I'm descending into the cave... it's about a 25 foot drop and the last 10 feet you're suspended on the rope before you reach the bottom of the first room. From there it's possible to climb... though it's much easier to have a rope to hold onto since it's still very steep.
In the end Peter was the extreme explorer... he slipped down into a muddy looking round hole (that I avoided because I was a having wimpy thoughts of death and despair) and located quite a lot more explorable space. In the end, we were left with a feeling that the cave isn't that stable... a lot of what we explored this time wasn't accessible a couple years ago on our first trip. That seems awfully fast for a cave to be changing.
