Features of Dorset’s Jurassic Coast
<p>This is a shingle ridge that connects the massive lump of limestone known as Portland to the rest of Dorset. It stretches for a total of 18 miles (29 kms), is up to 60 feet (18 metres) high and has created a salt-water lagoon, known as The Fleet, between itself and the mainland. At the far western end of The Fleet is the famous Abbotsbury Swannery.</p>
<p>A strange feature of Chesil Beach is that the pebbles that comprise it are graded in size, from “duck eggs” at the eastern end to “marrowfat peas” at the western end. Experiments have been done that demonstrate the process by which this happens — marked large pebbles will eventually be transported by the sea from west to east by the process of “longshore drift”.</p>
