Summary

The paper represents a reassessment of the drift stratigraphy at Porth-clais. The characteristics of the various Pleistocene deposits at the site are analysed in detail, and the sequence of drifts is then examined in its regional context. While the age of the raised beach at Porth-clais is still open to doubt, it seems that the non-calcareous till was deposited during a Late Weichselian glaciation by the Irish Sea glacier. This glacier probably extended much further south in St. George's Channel than suggested by other workers, although the ice stream which crossed St. David's Peninsula may not have been very thick.
