In reply to Will Hunt:
Glad you enjoyed them Will. I knew the crag would get popular one day - its only taken about 25 years. A team of us gave the whole buttress a thorough clean-up a couple of years ago but it would be worth giving Genesis another quick brush. At least then you'll get a sneaky look at the gear placements and may even spot the secret hold! The finishing jugs get overgrown each year but the mulch and moss pulls off easily.
