Summary of site:
Gortmaconnell Pot and Little Gortmaconnell Pot are adjacent shafts developed by the enlargement of extensive vertical fissures. Gortmaconnell Pot is 18m deep to its boulder floor, leading to 15m of undistinguished passage. Two separate surface streams merge in the pot. Little Gortmaconnell Pot is the deeper of the two with a shaft of 5m to a scree slope, followed by a second of 16m ending in a 15m passage, with a further 16m descent to a complex of old, deserted phreatic passages (formed below the water table), unmodified by later vadose water flow.
These potholes are a little over 100m to the south east of Formation Passage in the Prodís Pot system and it is believed that the streams sinking here provide the flow in that passage.
