Updated 6th October 2013

The entrance to this excavated site lies below a cabaña in a field, at the top of a shallow gully feature. The strongly draughting entrance originally closed in to a dig over fill with a strong draught. Two points in the entrance were dug, one of which broke through under a sandstone bed into a reasonably sized chamber, with the draught coming out of floor at several points.
A likely-looking draughting slot in the floor was attacked and, after digging through a shale bed, it was decided to take out a large boulder. This allowed a view down of 2-3 m through a small gap in boulders. Whilst trying to remove some of these an overzealous prod resulted in a bit of a collapse. The hole is now calming down. This area draughts out strongly. (No length given).
A further visit in 2013 confirmed it is a major project.
