Area position

Updated 27th September 2012

A hole first noticed when a stream emerged after torrential rain. This resurgence has been explored for nearly 80m with possibilities for extension through a draughting "spidery duck" and at the end. The Spidery Duck was pushed in the summer, 2012, during very dry conditions and after digging a trench. About 15m was gained around a number of bends until a slight narrowing prevented progress.A chamber could be seen ahead with a strong, cold draught. This passage is the source of the water that resurges.
