I don't think the prospects of digging in Carslwark are that exciting - porth and the digs Tommy talks about will go to EDHC (making probably the most squalid through trip in Derbyshire?)
Also the connection between Carlswark and Gimli's Dream needs checking, we reopened it about 7 or 8 years ago, not John Beck's original connection, but a bypass to the left of the concreted connection. Rumour has it that mud/scree/gravel/grot has fallen into it.
The latest date on John Beck's survey for Carlswark is 2009 but there isn't a revision history, so not easy to see what has changed since 83.
IIRC he resurveyed a bit that was a tiny bit out. The bit from eyamdale shaft to merlins was concreted on purpose, dunno when
this would be where the miners originally had access to Clog passage from I believe. You will see some old stacked deads, and the passage is named because cavers (John Beck?) found little kiddies clog prints in there when originally explored,
Bad Behavior has blocked 1501 access attempts in the last 7 days.
