Hi Guys,
The beer can was not ours, though perhaps it was of my generation.
Thanks for clarifying the sumps location on the Smallcleugh random.
I am working from memory here, but interestingly further down the passage, you cut Carr's Cross vein, where a dig might access a flat never before seen!(rhs. Going in bye ).
Further on leads to a sump which goes via a stope into a branch of Capelcleugh horse level.
(some of the exploration we did in conjunction with WCMRG)
hope the info helps!
