Sea Stacks and Wave, Port Campbell National Park, Victoria, Australia
(Click image to enlarge)
The unusual sea stack in the foreground of this image is composed of thin layers of harder rock alternating with thicker layers of softer limestone that erodes more quickly. The vibrant orange coloration seen here is due to iron oxide deposits. These elements together with the contrasting green-blue and white surf create a unique scene along Victoria's coast.
