Taken near my previous posting on the beach near Vik (Southern Iceland), these basalt columns were part of the cliffs that back onto the black lava-sand beach.
The columns are formed when magma from volcanic eruptions cools, and the subsequent contraction of the material causes cracks to appear in hexagonal patterns, hence creating the cracks. The Giant's Causeway in Northern Ireland is another example of these columns.
Again, as with my previos post, the photograph is taken in colour, but the bad weather at the time and the lack of natural colour in the surroundings make the photo look like black & white.
