Just to update people, the new entrance is now called North by North End Pot as the original Earby dig at the other end of the shake hole is called North End Pot and you can't have two things with the same name.
Most of Sam's original exploration ropes have now been removed (or were planned to have been) so the Masongill traverse team probably only got down them by the skin of their teeth.
To repeat others, can people keep away a little while longer whilst things get finished up. The survey needs another trip to tie into the bottom of Llean Bean and I really don't want to be wandering about down there in my own little survey world with people coming in from above. Sam also has stuff to finish off at the top of the aven which is high above the connection point.
