  A strongly draughting hole by the track. This was excavated on a number of occasions over the summer 2018 and Easter 2019 where the shored shaft was left about 5m deep with more materials ready to carry on the work. Excavations in the summer 2019 encountered a small "chamber" on the uphill side and included pinning some potentially loose boulders. Work continues.
