Two exposures of remnants of the raised beach platform at Parrog, in front of the houses and not far from the old lifeboat station at Cwm. There are not many remnants left, but these two are quite spectacular, about 3m above the current platform which is somewhere between HWM and LWM. Interestingly enough, these remnants are on the western flank of the estuary -- just like the spectacular traces at Poppit, on the Teifi estuary.
There are no traces of the raised beach itself on these platform remnants, but there is one exposure of broken bedrock breccia overlain by solidly cemented sandrock with traces of horizontal bedding. The exposure is limited in extent, and one cannot see how these deposits relate to the till deposit seen in the vicinity in other cliff sections.
