On a trip there this weekend, we found a white rope (with spit hangers connected to the rope ??) attached to a flake of rock by a sling which had presumably been washed off the shelf and was hanging in the water over the waterfall. It was pretty damaged.

We also found a yellow rope wrapped around rocks lower down just below the pitch. This had pre tied knots which look like they were set for Myers Leap. 

Both ropes are back coiled up and attached to the sling around the flake.

The next handline was pretty damaged too but usable if needed.

Cracking cave.
