Gerduberg (Gerðuberg) is a row of perfectly shaped hexagonal basalt columns that resemble a fortified wall in appearance. They run along a cliff on the south side of the Snӕfellsnes peninsula, in western Iceland. The columns range from seven in height and up to a meter and a half in width. The cliff itself is more than a kilometer long.
The most remarkable thing about Gerðuberg is that the columns are so geometrically symmetrical that they appear to have been carved by hand. However, such symmetry has a scientific justification. During eruptions thousands of years ago, rivers of lava flowed off the cliffs here, in very even streams. The sea cooled them rapidly, causing them to take on this unique shape. You can read more about how this and other volcanic wonders were formed in the Stunning Effects of Iceland’s Volcanism guide.
