I agree with M.E. I haven't seen the latest photos posted today because I have just come in from a day's walking...........in Cwm Cwmorhin! I passed the slate mine as we were going up to to the head of Cwm Cwmorthin and Cwm Croesor and carried on above up on to Moel Druman and back. It was beautiful up there today and I'll put a few pics on tomorrow to go with the ones that you will surely post now the question is solved!
