A large, 3m wide and 10m long feature. A single ladder lands on a slope of debris to a horizontal slot into an alcove. Flat out passage leads off through a stal grill to a chamber with inlets and holes down. The holes take water and draught but digging is necessary to progress.

When seen at Easter 2013, it was noted that the passage undercut was on the north side of the shaft and not the south and it would appear that the whole survey is 180 degrees out. The survey (and 3d file) have been corrected to take account of this.
