   A draughting entrance has been dug to a wide crawl into a small hole down into walking passage and another dig. The cave presently ends at a sand / mud floor with a hard calcite covering which has been excavated for some 14m. into a wider area. A bar and hammer is required.
   The hole couldn't be found at Easter 2013 but was at Easter 2018 and re-explored.
