The Yorkshire Dales National Park is famous for its classic limestone or 'karst' scenery. The hard grey rock was laid down at the bottom of tropical oceans millions of years ago and is actually made up of the calcium-rich skeletons and shells of billions of tropical sea-creatures. Their fossils can easily be discovered if you know where to look. Our iconic limestone pavements are flat areas of rock scraped bare by ancient glaciers and dissolved away by rain water over the thousands of years since. Cracks called grykes are home to special plants in their damp dark depths. The slabs above are known as grykes.
