| Description: | |
The Mullyard stream is a tributary of the Lurgan River. This stream sinks into the Dartry Limestone at its contact with the Meenymore Formation and is assumed to feed to risings a short distance to the east in the Lurgan River Valley. Mullyard Sink Cave is 120m of small passage in cherty limestone trending southeast to a sump which has been dived for 3m and is still open. The assumed resurgence is impenetrable. | |
