Hi guys,
         i visited your hut last week, which was amazing by the way! and i took a day off but couldn't stay away from things caving so i went and stuck my lamp down the top of these two digs and they interest me a lot. the only information i have from one of them is the article about babysitters dig in the '96 (50th) anniversary journal and i presume by the size of the operations that work has progressed since then!

Lots of stuff already published here.  :read:

Notably about how to turn the pursuit of new cave into improbably massive (over-)engineering projects!
