It's still there . At one stage it was Devon's deepest dig but I think Wolfsgrove has overtaken it. The diggers got down to probable water level but it didn't open out. Always draughted though and still accessible. Getting spoil out was the big problem as there was nowhere left to back fill. Huge potential in the area lying as it does over a large resurgence but sadly the best bet, Rydon Cave, is covered in dumped overburden from the dual carriageway outside. A concerted effort with a digger might re locate it. John Jones says on a cold day you could see steam rising from the spot where the cave is. That cave also went to water but was never properly explored below water level.
