The superficial deposits at Morfa‐bychan have previously been interpreted as deposited by Welsh ice. A reconsideration, including: stone orientation analysis, suggests however that they consist of screes and solifluction deposits with subordinate rain‐wash gravels, and a thin loess—the whole laid down under periglacial conditions, when the Irish Sea ice no longer reached the area. There is no direct evidence for dating but their volume and field relations suggest they represent the deposits of the last glaciation.
