Geology at The Cliffs of Moher. The Cliffs form part of the Burren and Cliffs of Moher Geopark which was awarded membership of the UNESCO in 2011. Quarrying of the flagstone that occurs along the Cliffs of Moher and in their vicinity was a substantial industry in the 19th & 20th century.
Cliffs of Moher Geology The rocks that make up the Cliffs of Moher were formed over 300 million years ago during the Upper Carboniferous period. Bands of Namurian sandstone, siltstone and shale are exposed in a spectacular fashion and here one can study an example of a sedimentary basin normally only visible under the sea.
Since 2011, they have formed a part of the Burren and Cliffs of Moher Geopark, one of a family of geotourism destinations throughout Europe that are members of the European Geoparks Network and also recognized by UNESCO. The cliffs are also a "signature point" on the official Wild Atlantic Way tourist trail.

The rocks that make up the cliffs were formed over 300 million years ago during the Upper Carboniferous period; you can see bands of sandstone, siltstone, and shale in the paving of the cliffs.

At the Cliffs of Moher Visitor Experience you can learn about the formation of these famous cliffs; why they are of such international importance in terms of natural and geological heritage; and why the cliffs are a Special Protection Area. At the Cliffs of Moher, you can learn about the cliffs either indoors in the Atlantic Edge exhibition, or outdoors on the cliffs themselves.
Compared to the nearby rocks of the Burren, the shales, siltstones and sandstones that make up the Cliffs of Moher and the area south west of Lisdoonvarna and Kilfenora were formed much more rapidly from sand and silt being washed into the sea by a major river system which has long since disappeared.

The Cliffs of Moher is by far one of the most popular tourist destinations in Ireland, attracting over one million visitors each year.. The Cliffs of Moher are approximately 14 km long, and they rise to 214 meters (just above 700ft) at their highest point, just north of O’Brien’s Tower.
Geology alive! The Burren is not a barren and boring museum of stones, monuments and scientific curiosities. Quite the contrary, it is a living place teeming with nature’s bounty: ordinary and exotic rocks, plants, animals, insects and birds.
In geography and geology, a cliff is a vertical, or nearly vertical, rock exposure. Cliffs are formed as erosion landforms by the processes of weathering and erosion. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers. Cliffs are usually formed by rock that is resistant to weathering and erosion.
