Description: Near Brein Phort, north of Loch Tarbert, west coast of Jura, Argyllshire. Ancient sea caves in quartzite cliff at edge of postglacial raised beach. Cliffs made of Jura Quartzite (Islay Subgroup, Argyll Group, Dalradian Supergroup, of Neoproterozoic age). Quartzite is well-bedded, and dips at about 10 degrees to left and away from camera. Grassy area in front of cave forms part of postglacial raised beach. Caves eroded along bedding planes and vertical joints in quartzite while postglacial raised beach was active. Screes and piles of quartzite at foot of cliff have formed since retreat of sea to present sea level. Level surface at top of cliff with scattered shingle on it in distance is late-glacial raised beach, c. 20 m. above level of postglacial raised beach.
