The Causeway stones are basalt and due to an ancient (65 million years ago) lava flow as well as hot and humid conditions interspersed with colder air, caused the geometric fracturing of the stones. I believe there is one area like this in Scotland too, but other than that a very unique configuration. The stones are all six sided and broken into layers. Some have tumbled down to form a mosaic of stone. Others still stand in precarious looking columns.
|Ireland 2007–Giants Causeway|
The pictures are pretty much self-explanatory. Amazing to look at but we didn’t do the long hike around to the Chimney and the Organ. It would have been a couple of more hours and we had many places to hit. In the afternoon now, there were fewer clouds but a haze had developed.
The Causeway stones are grayish to red where the water has not hit them. But wherever the sea water has licked the stones they take on a black hue. This gives some interesting gradations of color. Signs posted said to stay off the black rocks as the waves could sweep you away. After a similar incident on BC’s coast the year before where people where swept off of rocks, I paid attention. The sea is very wild along here .
Some of the Causeway stones are pitted and eroded by wind, rain and sea. They had been dished by the elements and began to remind me of ancient vertebrae. One of my favorite pictures of Ireland is the one of the Causeways stones (ocean behind me) with the pitted rocks leading up to a hill.
Maybe next time I’ll do some hikes through this area. It’s pastoral and rolling and the variations in green are picturesque. Giants Causeway is definitely worth seeing and seeing again.
