A stream enters a tight bedding plane and opens into a passage which continues for 90m before ending in a 4m deep shaft. Within a few metres, a second pot 5m deep opens into a boulder strewn chamber. Two further shafts can be climbed to a passage at stream level, where two underwater ducks end at a sump. Beyond the sump, which is 5m long, are 15m of low passage that leads to a further small pot, also sumped. The stream is thought to enter the Marble Arch Caves system but exactly where is yet to be discovered.
