How to find it
From Vigne Close turning, continue S until the next bend, where there is a widening and a track leading off on the left. Continue along the road for a very short distance; on the left is a small path through the trees marked with a couple of bits of flagging tape. Follow path to arrive very quickly at the hole. Looks impressive.
Details
Pitch is around 25-30m. Followed by small draughting hole which could be dug?
