   A good draughting dig. This was originally blocked by a boulder that was removed in 2014 revealing a strongly draughting narrow rift. A rope is useful to aid climbing out although it was laddered in 2015 and subsequently.
   The base was too narrow to haul rocks out but one of the walls was susceptible to a hammer and chisel as shown in the video. A visit in 2017 probably extended the depth to about 14m. At Easter 2018, it was "cleared out" and some enlarging occurred in August.
   A break-through occurred at Easter 2019 when, on a couple of trips, snappers were used to remove obstructions and a free climb gave access to a 4x4m chamber. There is a possible dig under a boulder in this chamber but it needs a hot day to follow the draught.
   In the summer 2021, progress was made removing rocks in the roof of a constriction. A sandy floor with sandstone boulders appears accessible through a draughting dig in the floor. One year later, rocks and mud were removed from the floor and the entrance pitch was enlarged. At Easter 2023, one visit enlarged the entrance and removed material from the floor of the lower section.
   Nine visits in the summer 2024 worked at enlarging the shaft to allow larger people to work down the hole. The shaft was found to be strongly draughting at the end of October.
