A detailed photograph of the limestone-platform at The Burren. It is this heavily weathered limestone that makes The Burren famous. The reason for this is that limestone easily dissolves in water. Rain water is able tot penetrate deep into the platform along joints in the limestone, dissoluting the rock along these joints and creating the cracks visible in the picture.

These cracks are called "grikes", which are about  5 centimeters wide and 10 to 20 centimeters deep. The grikes are home to a variety of rare plants. The more or less tabular blocks of limestone are called "clints". In general, the formation of grikes and clints is an example of "pavement karst."

So far for The Burren. Later that day we drove further to our guesthouse near the tiny village of Corrandulla, located some 15 kilometers north of the city of Galway.
