A 3.3m pitch drops into a 4m rift which chokes to the northeast. The way on is through an excavated chicane into larger passage. At the end a 12m circular pitch drops into a tight rift with a strong draught and good echo. This will require a lot of work to enlarge. In 2012, some digging occurred in the boulder choke.
In August 2013, a dead cow was blocking the entrance.
