St Brides Haven solifluction deposit

Solifluction deposit ('head') on the east side of St Brides Haven, Pembrokeshire. This consists of a jumbled mass of angular sandstone fragments derived from the underlying Old Red Sandstone and was formed by freeze-thaw action at the end of the last glacial period. These deposits would have been part of the permafrost layer which partially melted during the summer months, refreezing again during the winter.

Small-scale fold-like features near the base are cryoturbation structures, probably due to ice-wedging as the refreezing permafrost layer expanded upwards.

The walking stick is about 0.9 m long.
