Why this matters
Porth Lefesig is a coastal bay in Gwynedd, Wales, characterized by sea cliffs composed primarily of Silurian greywacke and mudstone, formed around 440–420 million years ago. These rocks were deposited in deep marine conditions and later uplifted and eroded to form the present-day coastal features.
