Description: South of Dougrie, west coast of Arran, Buteshire. Fossil sea caves. Like much of the west coast of Scotland, Arran has good examples of raised beach features at various topographical levels. Here, abandoned sea caves have been excavated in a cliff of Lower Old Red Sandstone conglomerate, forming the back edge of a raised beach. The photographer is standing on the wave-cut platform associated with the raised beach. The massive nature of the conglomerate (i.e. it is not well bedded) can be clearly seen. Such sea caves are quite common along the Clyde coast and were formed when the sea level was higher than at present. This typically occurs when an ice-cap retreats, rapidly releasing large quantities of water which raises the sea level. However, through time, the land rises isostatically with the removal of the ice load, and the sea-level appears to fall again relative to the land.
