A narrow rift dug on at least 7 occasions in August 2013. The site appears to be an old stream and it has developed a good draught. The hole has been walled and made stock proof. One digging trip was carried out in August and several in November 2014. By that time, both the inverted "V" and alternative narrow, draughting rift required considerable further work.

Further capping was carried out in July 2015 and October 2017.

A new downward dig was started at the base of the entrance slope in October 2022.
