The entrance is in a cleared depression behind a barn and is probably a cold store. In June 2008 the situation was the draughting dig had been enlarged to the top of a 12m pitch. Unfortunately, the top of pitch was a collection of large loose blocks "supported" by several larger blocks which had little visible support. It was felt a safe descent was not possible yet from the point of entry or from the far side of the pitch. A descent at that time was thought to be suicidal.
In the summer, an attempt was made to drop an offending boulder with the help of a weighted tub. This failed. The next person in ignored or didn't realise the "risk baggage" and passed over the top and down the far side. At the base, a small streamway on sandstone is met. At a T-junction, downstream goes 3m to a sump while upstream chokes. In August 2012, in a very dry summer, both up and downstream areas were looked at again with "inconclusive" results.
At Easter 2017, the downstream sump was checked and, although the passage continues, it is far too narrow.
The length and depth above are an educated guess.
