Why this matters
Smooth Rock is a sea cliff composed primarily of Devonian slate, formed around 380 million years ago through the regional metamorphism of mudstone under high pressure and temperature. It is notable for its relatively smooth surface, likely shaped by persistent wave action and coastal erosion along Cornwall's rugged coastline.
