Abstract: Excavation for a water main in 1979 revealed an underground stream flowing through a pipe-like conduit in clay, 2 metres below ground. Several active sinkholes near the site are linked to the streamway. It is thought that the streamway developed as a cave in a thin calcareous bed, interbedded among mudstones, that has been locally removed by solution.
