What is the ground like in Clwyd?
The North Wales coalfield runs beneath parts of Wrexham and Flintshire, where historic workings are recorded, while the coast and vale have glacial clays and the hills are older hard rock.
Parts of Clwyd lie on a former coalfield, so a coal mining search is worth checking if movement has no obvious cause.
