Description

Looking east this is limestone pavement on the west side of the Burren. This area is near Black Head and is a popular location for visitors to experience the structures close-up. The weather is often dull and showery and the rocks can be extremely slippery to walk on. The Aran Islands are also nearby.

The Burren (Irish: Boireann, meaning 'great rock') is a region of environmental interest primarily located in northwestern County Clare, Ireland, dominated by glaciated karst (or sometimes glaciokarst[1]) landscape. It measures, depending on the definition, between 250 square kilometres (97 sq mi) and 560 square kilometres (220 sq mi). The name is most often applied to the area within the circle made by the villages of Tubber, Corofin, Kilfenora, Lisdoonvarna, and Ballyvaughan, and Kinvara in extreme south-western Galway, including the adjacent coastline.

A part of the Burren forms the Burren National Park, the smallest of the six National Parks in Ireland, while the full Burren and adjacent territory including the Cliffs of Moher are included in the Burren and Cliffs of Moher Geopark.

As the ice-cap moved into the Burren from the north-east it carried with it some debris, such as the granite boulders (Glacial erratics) on the coast line. However, the main action of the glacier was to scour the rock clean off any superficial cover that formerly may have lain on the surface, thus exposing and smoothly polishing the underlying bedrock which we know today as the largest classic karst limestone pavements in these islands. Pavements are made up of two separate but integral parts known as clints and grykes. Clints are the blocks of limestone that constitute the paving, their area and shape is directly dependant upon the frequency and pattern of grykes. Grykes are the fissures that isolate the individual clints. The most dominant gryke system runs almost north to south and there is a secondary less-developed system at right angles to it.

Grykes can stretch for hundreds of feet until they suddenly terminate or are lost beneath superficial deposits. Grykes are usually straight but are occasionally curvilinear.
