In Northern Ireland there is a remarkable geological formation that is tied up with an Irish folk legend. It’s called The Giants Causeway and the legend harkens back to a period when giants were supposed to have walked the Earth.
It’s an amazing place where 60 million years ago molten basalt came into contact with chalk beds, forming a lava plateau. After that the lava cracks and fractures. Cracks opening along the cooling surface get propagated downward, resulting in the long, well-defined columns known as columnar basalt. Leran more about the Giants Causeway HERE.
