Oh so you've moved into the cave.
There seems to be a lot going on in that area that needs a good look at. If you go through the window into the small chamber, there's also an interesting dig in the floor and I reckon that a dig above there might repay a bit of effort.
Can flood there quite spectacularly as well. We went back there after the cave had been shut by flooding for a few months to discover that the chamber had flooded to quite a depth. I'd left my brew kit on top of the pile of breakdown in there and it got swept away. Found a plastic cup on a small ledge on the wall opposite that was just in reach.
There was even evidence of water flowing through the Brickyard and down from that aven. So, all in all an interesting place.
