City of canals with rocks that aren’t rocks

City of canals with rocks that aren’t rocks

Mandurah is the second largest city in Western Australia with a population of 83,000. It was originally a sleepy area of holiday communities but in a decade has grown into a city of modern residential canal developments popular with families and retirees with a great freeway and direct rail line to the centre of Perth, the state capital.

The shallow waters of the estuary, inlet and rivers are ideal for off-the-beach sailboats and shallow draft power boats. The estuary is nearly twice the size of Sydney harbour and every day we spotted pods or individual dolphins, and a large group of 70 or more black swans.

It is also an area of natural wetlands with a huge array of birdlife that we saw while walking

as well as on the water when we cruised the two rivers: The Serpentine River and the River Murray.

One of the unique things we saw while in the area was to visit the Thrombolites at Lake Clifton. Don’t worry we didn’t know what they were either and they aren’t rocks.

‘Thrombolites are ancient forms of microbial communities that photosynthesize…..They are now only found in a few places in the world….The ancestors of thrombolites and stromatolites are thought to have contributed to the increase in oxygen in Earth’s atmosphere.’ (source: Wikipedia).

The ones we saw at lake Clifton are 2,000 years old!
