I've been reading the latest edition of Cave and Karst Science as well and would highly recommend it to anyone with a serious interest in Ogof Draenen. There is a brief history of exploration followed by papers on the evolution of the local landscape (conclusions influenced by observations within the cave), bats, hydrogeology and speleogenesis. All the papers are interesting and informative. The two geological ones perhaps need a couple of reads to understand all the main points presented (definitely in my case - I still have the term 'Marros Group overstep' going round in my head!) The papers build on data published previously but with much more detail. The information presented here could give clues to finding many more kilometres of passage. Like I said, well worth getting hold of a copy if you haven't already got one. Well done to all involved.
