The Green Man's Western Australian odyssey is now documented. Here is one of the more interesting photos.

They are stromatolites at Hamlin Pool near Denham. Stromatolites are the result of primitive life forms that first existed on earth 3.5 billion years ago. The dome shaped structures reach up to 60cm in height and are formed by single celled organisms called cyanobacteria. They are continuing to grow.
