Thrombolites are clotted accretionary structures formed in shallow water by the trapping, binding, and cementation of sedimentary grains by biofilms of microorganisms, especially cyanobacteria (commonly known as blue-green algae). Stromatolites are similar but consist of layered accretions.

Mount John Road, is the closest road on Google Maps. The parking of the Thrombolites is at the western end of this road.

Living thrombolites, fed by calcium carbonate from the fresh-water aquifer, are found on the eastern shore of Lake Clifton and fossilized microbialites are found on the shores of other lakes in the Yalgorup system

There is only one other place in the world where thrombolites exist in water less salty than the ocean.

The Ramsar wetlands of the Yalgorup Lakes System are also the breeding, moulting and feeding grounds for thousands of endemic and migratory birds each year.
