This rock stack is called “the Razorback”. The sharp edges and bumps along its back are caused by wind-blown spray, which hardens small areas of rock. The softer rocka round these erodes away, leaving an uneven surface.

Wave energy channelled along the side of the stack carves the deep smooth grooves just above sea level. With one wave every 14 seconds, there’s a lot of erosion over the years.

The Razorback once extended much further out to sea. The force of the waves gradually eroded and undercut the base of the stack. Vertical cracks in the rock were widened by rainwater forming a line of weakness. Huge blocks of rock then collapsed into the sea, leaving a rock shelf.
