Anyway, some good came of it, because I discovered that there is a rather fine exposure there at the moment, at the head of the bay, where the footpath comes down to the pebble beach. We can see about a metre thickness of beautiful pseudo-bedded slope deposits (made of mudstone fragments from the adjacent cliffs). On top of that is a layer of "churned" slope deposits, almost certainly attributable to the movement of ice across the old shoreline, pressing south-eastwards. This is about 50 cms thick. And above that is classic Irish Sea till, fine-grained, calcareous and containing a scatter of small erratics cobbles and pebbles. There are some larger clasts as well, but the exposure is obscured by slumping and vegetation, so the thickness is difficult to determine. It seems to be at least 2 m thick.
So the early part of the glacial cycle is represented here -- and of course the section ties in very nicely with that at Aber-mawr. Here is the sequence, in its correct stratigraphic position:
