a cave conserver, no doubt in my mind.
These idle pencil marks that I posted up are (sorry, were) actually meaningless initials from casual visitors. They are (sorry were), however, the only evidence we have of visitors into these ancient workings following a monumental storm in 1911 which washed open three old workings. The evidence of the flood is everywhere - silt, demolished drystone walls, huge boulders tossed around like playthings - this grafitti identifies one of the three entrances that were temporarily opened.
More recently I think I have identified chalk arrows drawn on the walls by these early explorers, and a couple more associated names. If this is the case, then it is possible to follow in the footsteps of those early venturers, and see how far into the system they penetrated.
