Although the building blocks of the Causeway formed some 60 million years ago and continue to exert a major influence on the landscape, the detailed features we see today are much younger. Indeed, it is only as recently as 15,000 years ago that the coastline emerged from beneath a of ice. Since this time, a series of landscape adjustments has not only produced the three promontories that comprise the Giant’s Causeway, but also the many steep-sided headlands and deep bays fringed by vegetated scree below basalt cliffs. These adjustments have consisted interactions between a complex geology and marine erosion along an exposed Atlantic shoreline to produce a wide array of active and relict slope failures. This spectacular landscape owes its existence to the interactions of:
The Lacada Point headland from lower path. Here it is easy to distinguish both the Lower and Middle basaltic formations and the red Inter – Basaltic palaeosol.
Panoramic view of dormant and active screes at Port Reostan.
Outstanding view from Hamilton’s Seat, showing the characteristic pattern of bays and headlands within the Causeway Coast.
View of the Giant’s Causeway from Aird Snout on a stormy day, with the road that connects it to the Visitor Center and the ‘Causeway Bus’ at the turning circle.
