This site started as a muddy dig just off the side of a shallow valley by an old wall. Stones rattled down for a couple of metres and there was a warm draught out on a cold day.
The entrance was excavated and this opened up a 10m deep rift, climbed down to a chamber. A flat out crawl was passed by further digging to a boulder choke. This was also dug through to a continuation where the flat-out crawl developed into a rift and became too small.
