New rock armour The notoriously unstable cliffs are protected here by newly-placed rock armour. This provides two functions, weighting the toe of a potential slip and reduction of wave energy and erosion. It is not obvious whether this is a private initiative or part of a more systematic scheme. See <a href="https://www.geograph.org.uk/photo/3175708">SH3040 : Fresh landslide</a> for context.

Fresh landslide After a notoriously wet Summer, water-saturated ground has collapsed just a matter of days prior to this visit by the North Wales Geology Association. Bramble bushes are still fresh and green at the toe of the slip, and wave action has not carried away a significant amount of fine material, while a large boulder (<a href="https://www.geograph.org.uk/photo/3175721">SH3040 : Erratic boulder</a>) stands on end where it has come to rest.
Fresh landslide
After a notoriously wet Summer, water-saturated ground has collapsed just a matter of days prior to this visit by the North Wales Geology Association. Bramble bushes are still fresh and green at the toe of the slip, and wave action has not carried away a significant amount of fine material, while a large boulder (SH3040 : Erratic boulder) stands on end where it has come to rest.
Erratic boulder This fine erratic boulder has just fallen onto the beach as part of a landslide (<a href="https://www.geograph.org.uk/photo/3175708">SH3040 : Fresh landslide</a>). It is made of Carboniferous Limestone, and may only have travelled from Anglesey, but although it is very angular and fresh, one side has been rubbed vigorously on bedrock and flattened. This surface carries a record of its transit and abrasion in the form of dense and (mostly) parallel striations. Sadly, these features are soon lost as the limestone dissolves in the rain. A pencil gives a scale.

Cemented gravels This material at the base of the cliff resembles poor-quality concrete, but is natural. Gravelly horizons within the glacial material are conduits for water. In these deposits a great deal of calcium carbonate is present in the form of limestone debris which has been ground down from bedrock of various ages within the Irish Sea Basin, which was dry during the glaciation of the area. Subsequent dissolution and re-precipitation by percolating groundwater has resulted in hardening of the gravel to a rock-like consistency. It is a curious anomaly that this area also suffers hard drinking water from local boreholes.
