Photographer's Note

"60 million years ago the land here was different, the climate was warmer and vegetation thrived.
Tectonic plates were moving, Europe and North America were moving apart.Magma from deep inside Earth spewed through cracks in the surface, lava flowed. It cooled in contact with the air and rock, hardening into Basalt.

For hundreds of years, all was relatively quiet.Then the Earth cracked open again and more lava forced its way out. This time, the lava cooled slowly and evenly in a deep pool.Cracks travelled through the cooling rock,creating the columns we see stretching up, and making the honeycomb pattern we can see today.

There are over 40,000 columns at The Giants Causeway, most are six sided, but there are others with fewer or more sides. Later eruptions left these columns hidden deep underground.

It took millions of years of erosion for the columns to begin to be revealed.The sea level rose and fell then rose again. It wasn't until after the last Ice Age, about 15,000 years ago, that the columns were revealed at the shore as they are today."

With the sea lapping across the basalt it can be very slippery! So watch your step! For those are not able to walk far, there is a bus from the visitors centre that brings you down to the columns.
Pictures do not really do this site justice; it really is an amazing natural phenomenon.
It is such a popular place, it is very difficult to get a shot without people somewhere in the frame, but I guess that they do give an idea of scale.
