This was a good day, Quentin and Robin headed in around 1pm to do some surveying we didn't get to finish last time, we went as far as our previous limit and persuaded the cave wall to let us through into 'caverns measureless to man', well at least 100 meters anyway of lovely gour floored stream passage. We spent a while at this, and on the way out we decided to recheck the previously written off upstream end of this passage named 'Midnight Series'. To our surprise this went too, at stream level and very pretty indeed. We will need another tip to complete the surveying in there and maybe some time spent taking some nice pictures, in the meantime here is a few snaps. At preset there is about half kilometer of new passage (300m already surveyed) and +/- 200 more to go.
