We passed this lookout on the way to Hamelin Pool.

We arrived at Hamelin Pool and here are the stromatolites.  Stromatolites are considered ‘living fossils’, part of the Earth’s evolutionary history, they are the oldest and largest living fossils on earth.  Hamelin Pool in Western Australia is a place of great interest to botanists and geologists as it gives an indication of what the earth may have looked like about 3.5 billion years ago, when stromatolites grew widespread across the water. Visitors can view these amazing life forms, without causing damage by walking on a purpose built jetty and looking down at the Hamelin Pool stromatolites below.

Stromatolites grow successfully and undisturbed at Hamelin Pool because the sea water is twice as saline as usual sea water, due to a bar across the entrance of the bay and also due to rapid evaporation from shallow water.  Stromatolites which are found to be up to a metre high are believed to be hundreds to thousands of years old as they grow at a maximum of 0.3mm per year.  Hamelin Pool in Western Australia is one of only two places on earth where living marine stromatolites exist.

Nearby is Hamelin Pool Homestead, complete with the Old Hamelin Pool Telegraph Station, which was built in 1884 as part of the communication line between Perth and Roebourne. The original building is now a museum housing many artefacts.

Here is the quarry.  You can still see the marks where bricks have been cut.
