Southern Outcrop

Area Map

The Southern Outcrop is the band of limestone that runs along the southern edge of the South Wales Coalfield. This is a fairly narrow band at its eastern end in the hills north of Newport and Cardiff, but it becomes a much wider lowland karst area as it runs through the Vale of Glamorgan, to be lost under Swansea Bay at Porthcawl (re-emerging at Mumbles and Gower).
