FONES CLIFFS is a four-mile cliff formation along the eastern side of the Rappahannock River, midway between the Route 301 bridge in Port Royal and the Route 360 bridge in Tappahannock. The cliffs contain diatomaceous earth and are visible from miles away due to their white color. This diatomaceous earth was formed millions of years ago, when all of this territory was underneath the sea. Sharks teeth and large sea scallops (the Virginia state fossil) can be found in these cliffs.<div><span><br></span></div>
