With Roz.
Some induced rapid speleogenesis required, 6no. holes drilled at the current end of Merlin’s, on the right-hand side, where there is a small gap over a calcited (?) blockage. Some of the holes were a bit awkward, especially with the longer drill bit (460mm), but the job was done.
A few puddles along the way after the recent heavy rain.
The evening’s task was brought to a satisfactory conclusion.
