Wave Rock, Australia
It is very, very, very easy to see where Wave Rock gets its name. Halfway between a rock face and the kind of tsunami only seen in disaster movies, the concave surface has been slowly weathered into shape across 2700 million years, and colourised by vertical stripes of algae. Despite its aquatic appearance, Wave Rock is hundreds of kilometres inland, in the heart of Western Australia’s southwest corner.
