   A small draughting hole in the side of a depression in a field where cattle are kept. A small bouldery "chamber" was originally seen that required to enter. Subsequent work at Easter 2002 dug down 4m to a tight entry onto a 7m pitch to an eyehole into the space below the shakehole. Further digging required.
   At Easter 2016, a group "poked at the entrance but didn't go in".
