Long time no see.
I have been in contact with Mary and Mel. The question came from a Russian caver living in Canada, it was basically what we found and where. Mel has supplied me with a digital copy of the book he wrote which covers the Tuva trip. I will be sending it to Mary next week.
I am still involved at SWCC, and am now also busy at in the mines at Nenthead, exploring, repairing collapses and carrying out maintenance on the buildings. If you fancy a trip down the mines give me a shout.
