Today we took a long drive to County Clare to see the Cliffs of Moher and the Burren. I've been doing all of the driving, and I am getting pretty comfortable on the left side of the road (although the narrowness of the roads I will never get used to.) The weather held out at the cliffs, and we had great views. We even saw puffins and whales. On the way back from the cliffs, we drove into the Burren and took a short hike. The landscape is otherworldly—it is a karst landscape "composed of limestone pavements with criss-crossing cracks known as "grikes", leaving isolated rocks called "clints." The limestones, which date from the Visean stage of the Lower Carboniferous, formed as sediments in a tropical sea approximately 325 million years ago. The strata contain fossil corals, crinoids, sea urchins and ammonites. This bed of limestone is up to 800 meters thick." (Wikipedia)
