Irish Sea till at West Angle

 

On going through my notes from a few years ago, I discovered a reference to a "wonderful exposure" of clay-rich Irish Sea till immediately to the right of cutting B as shown on the above diagram.   Most of the till exposed at West Angle is reddish in colour and has a sandy and even gravelly matrix, but in the chance discovery of this exposure in the gully that runs down to the beach, I saw "classic" Irish Sea till with a high clay content, reminiscent of the tills at Druidston and Abermawr.  There were many fragments of ORS incorporated, including striated pebbles, and there were also lignite and shell fragments as at Abermawr.  Unfortunately I had no time to collect samples.

This reinforces the view that this till is of Late Devensian age.  It's the southernmost exposure of the Irish Sea till on mainland Pembrokeshire, but there are other exposures further south, on the foreshore at Amroth and Freshwater West.
