Other well-known columnar jointing formations are seen at the Giant’s Causeway in Northern Ireland, Devil’s Tower in Wyoming, United States and on the island of Staffa in Scotland. There are also similar formations throughout Iceland, including a small cave on the beach of Reynisdrangar.
The base of this waterfall is noteworthy for its sharp rocks. New hexagonal column sections break off faster than the falling water wears down the edges.
