About This Puzzle
Did you know? Coastal rock formations like this are sculpted by hydraulic action — the force of ocean waves crashing into lines of weakness in a cliff face. Over time, this erosion carves sea caves, then arches, and finally isolated stacks that will ultimately collapse into stumps as the waves continue their relentless work. Source
