Bwlch yr Hysfa

Cliff

Why this matters

Bwlch yr Hysfa is a sea cliff composed of Silurian greywacke and shale, formed around 440–420 million years ago through sedimentation and subsequent tectonic uplift. It is notable for its exposure of ancient marine sediments and its location along the rugged coastline of north Wales, which reflects the region's complex geological history.
