Thinking about trying to get digital copies of any surveys of both mines & caves so they can be overlaid onto OS maps or google earth. I think the WSG did this for the caves many years ago, just need to find them. Doesn't seem to be a survey of Ogof Bwa Maen.
Got a copy of the Dinas plan (?copy of MRO plan) but the text is illegible. Also have seen a survey of Bwa Maen mine (across the bridge from Dinas) but don't have a copy. Can anyone supply better copies of either of these? (I suspect PB may be responsible for these).
Two workings I only spotted recently were an adit on the south bank of the river, between Wills Hole & the Dinas Rock carpark, & one shown on the OS map further downstream from the road bridge, havn't been up to either.
