A description and survey of the cave Bullock Pot is given. The cave runs east of the shale-limestone boundary and near its end picks up a large stream, believed to be the main stream from the Poulnagollum-Poulelva System. The cave is unusually arduous for Co. Clare. Also presented is a surface survey of the sinks between Bullock Pot and Pollcragreagh, which is the next major cave to the south, and a discussion of the past hydrology of the area.
