Pwll Du


A team of cave explorers and qualified mining specialists made up from members of the British Cave Research Association, South Wales Caving Club, Chelsea Speleological Society and Eldon Pothole Club (Derbyshire) carried out an excavation at Pwll Du (NGR SO 2457 1163) on Saturday 17th July 1999 with a view to regaining access to and carrying out a preliminary inspection of a hitherto lost tram tunnel, sealed to human presence for some 65 years.
