   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 remains of beetles in the guano. Work continued in 2020 and a lower series was explored in the summer 2021 - see 4732.
