A small, block-covered hole with a good draught that was dug out in 2016 to reveal a strongly draughting, 3m deep rift. Capping and further excavations took place in August 2018 to reveal a decorated, old cave passage with the draught coming from two narrow fissures going into the hillside. A voice connection was made with site 4417 from above a possible dig in the floor at the start of the second fissure.
