The entrance is in a tree-lined depression and has been wrongly tagged "873". Originally, a drop between boulders ended in a choked chamber. At Easter 2018, the entrance was enlarged; an alternative entrance dug open and sub-phoned (site 4732); a nearby draughting route excavated to walking passage and a run-in, and the whole system surveyed to a length of 82m.
Digging continued in the autumn 2018 when a large number of spiders were noted and a probable bear tooth excavated. More digging was carried out at Easter 2019 and bat droppings were noticed along with beetles eating the remians of beetles in the guano.
