Nice meeting you.
The 'tin sheets' have gone by the way, wondered about for ages up the wrong footpath until I saw a couple in underground gear.
Anyway found the place eventually, did what I came to do and marveled at the place. Been 25 years since I was last in there.
Large party of schoolkids met on the way out. very popular place.
Went on to Slaley Sough after, another nice little trip.
