Exposure at the northern end of Whitesands Bay, with a lodgement Irish Sea till overlain by deposits suggestive of an ice wastage environment -- similar to the situation at Abermawr.
One of the more confusing sequences in Pembrokeshire -- from the Trwynhwrddyn Peninsula at the northern end of Whitesands Bay. The two till layers were probably laid down in a single glacial episode very close to a wasting ice edge.
Parrog, Newport -- showing the classic sequence through the Devensian glacial cycle.
Gwbert, at the mouth of the Teifi estuary. This was a classic exposure of Irish Sea till and interbedded sands and gravels -- but the exposure was completely destroyed during coastal defence works.
Llanina, near New Quay. There is some debate in this area about tills derived from the Irish Sea Glacier and from the Welsh Ice Cap. This is one of the enigmatic coastal sections -- still not adequately studied.
