A Pudding Stone moved in 1984 from Back Lane to a roundabout in Horns Lane. This 2005 photo shows the conglomerate that was laid down some 50 million years ago as a layer over the chalk when this region had a hot, tropical climate. The layer was broken into chunks in the Ice Age less than two million years ago and these were carried into valleys by the melt-water. Boulders like this one are thought to have been used as way-markers by pre-historic man.
