In reply to tombeasley:
I was there last week - Cottage Rocks and Ousal were soaked through and seeping. The Green Boulders had the odd dry problem - but were mostly wet. Gentlemans rock was very wet at the bottom, but greasy above. In the end, I didn't do anything for fear that I would damage the sandstone.
I think the downpours have been too much for the Churnet for once - I shall avoid it until we've had a good dry spell.
