When you look at the bottom of the photo you can see layer upon layer of rock. Each of these layers represents a long period of time, during which particular sediments were deposited on the ocean floor. Each thick layer has a thin layer of a different composition in between, and these layers, over time, have been put under great pressure as the ocean floor was lifted and tilted until they became the shoreline, open to air, wind, and wave. The thin layers crumble and portions of the thicker ones are broken down by erosion and that is why they appear to be slightly angled and in retreating layers. What you've captured here, Roland, isn't just a very pleasing shoreline photograph, but pure evidence of the basic geologic nature of the earth--it's in a constant state of upheaval. It happens so slowly, however, that the true evidence is in photos like yours. I love it. I bet if you were to closely study these layers you could also get shots of aquatic fossils, plants and animals alike.
