Photographer's Note

General view of Giants Causeway site. Slack water and basaltic oceanfront.

The Causeway was formed during the tertiary period some 62-65 million years ago ( end of the Cretaceous period ).
The causeway area would have been situated in an equatorial region at that time - due to the fact that the earth's crust is floating on tectonic plates . The latter move slowly over millions years ( cf: Caledonian orogeny ) . The same formations can be seen at the tiny isle of Staffa,in Scotland, and they also occur in the surrounding landscape of North Antrim.
