Erosion along the coastline of Cardigan Bay, west Wales

Caption

New research has shown that "lost islands" mentioned in Welsh folklore, could be the remnants of a low-lying landscape underlain by soft glacial deposits laid down during the last ice age. Since then, forces of erosion have worn away the land, reducing it to islands, before these too were worn away and disappearing by the sixteenth century.
