In reply to Red Rover: Yes to both your questions! To be perfectly honest most of the routes in the article, because they are less travelled, can be a bit mossy and dry slower. Sadly, the start of the second pitch of Hiatus gets emerald colour in a wet period, but the rest of the route is so splendid it would be churlish to complain.
BTW, I'm astonished to read that over 4000 people have read (or at least looked at) this article. I really do hope I have inspired a few of those people to explore this neglected area, and would love to hear from anyone who went there as a result of reading it (as long as they're not asking for their money back).
