Re GG Rider
I thought that it was climbed on a winch meet and that the rock was very clean until near the top when light from the surface hit the rock and allowed vegetation to grow. People on the winch were warned about the ascent as seeing lights half way up the cavern/shaft walls could be most confusing.
Having been down there on the winch I do not see that getting mixed up with the cables would be a problem, also been down there under my own steam but that is another story.
It could do with a repeat.
Now another tale I heard was that two lads went down Alum (but I could have the wrong pothole there) with ice climbing gear to attempt an icicle that had formed, but found that it haven't reached the floor and they couldn't reach it.
How about Pen-y-Ghent Pot, didn't Pete Livesey free climb up all the pitches once. I'm sure there must be others that are feasible.
