Dave took Rohan this time in his learning of the cave. Me and james continued our survey finishing off a few leads, upstream sumped. Our biggest find was the upstream rift that was very tight and akward for about 20m before breaking out into a much wider rift. A sandy section temporarily stopped progress but James dug through this as it was drafting a lot. This entered a big chamber and we thought we had hit big stuff. The passages from hear led upstream very small and downstream, a bit bigger, but it soon got very tight in places thanks to lot's of shelves so we called it here.
