Afon Lliedi sinks.
« on: August 17, 2021, 02:54:12 pm »
There is a report today that the whole flow of the Afon Lliedi has disappeared into a sinkhole in Llanelli.

I don't know the area at all, but the site in Llanerch appears to be on the Swansea member of the Pennant Sandstone. Although there is limestone far beneath, perhaps a more like explanation is drainage into old coal workings.

Looks like you're right. NLS shows a coal shaft 50m to the NW under the roundabout!
