Drop down into loose chamber with precipitous slope, and across this is a short roof passage. In an alcove on the right is BLACK RABBIT CHIMNEY which descends to SQUARE CHAMBER with twin chimneys on each side. The west chimney leads to a series of crawls and avens, whilst the east chimney drops into MINT CRAWL which leads to a free climbable pot and a very unstable boulder choke.
The hole at the bottom of the entrance chamber opens out into SOUTH CHAMBER which has a muddy crawl straight ahead which is blocked by boulders. A hole to the left connects to MINT CRAWL and a slot between blocks drops to a lower chamber.
