Erratic boulders on South Pembrokeshire clifftops


Erratic boulder exposed in an inaccessible position on a vertical clifftop near the Huntsman's Leap, west of St Govan's Head.  This one is maybe a metre long -- heavily abraded and polished and bedded in a rough till made up mostly of broken limestone fragments.  The boulder looks to me ro be igneous, but maybe we will never know.  One day, before long, it will go crashing down to the beach below........


This heavily abraded boulder projects from quite a thick layer of reddish till -- again in an inaccessible position -- on the clifftop of Bullslaughter Bay, about 2 km east of the Green Bridge of Wales.  It looks to me as if it might be rhyolite........
