The Thrombalites of Lake Clifton and Heron Island, Mandurah Eastuary

Pelican Games

It was a beautiful pre Spring day out yesterday with some awesome 3D clouds hanging around all day.

Driving back from down south trip with fellow photogs Christian Fletcher, Ian Wise, Paul Pichugen and Tony Hewitt I saw these fantastic 3D clouds evolving all around me, so I made my way to the obvious water holes on the way back from down south and I wasn’t disappointed!

First stop was to Lake Clifton and the very ancient Thrombolites:

In case you were wondering what these things are, they are types of rare and extremely primitive life forms. They consist of single-celled bacteria which deposit layers of silt and calcium that slowly grow into rounded rocks. Scientists believe they are the earliest form of life on earth, dating back about 3500 million years, and the origins of oxygen in the atmosphere. These relics are mostly extinct and exist only as fossils – living examples can still be found growing in just a handful of places in the world. Shark Bay is the well known Western Australian example, but Lake Clifton is more accessible.

If you haven’t been there and had a look, take a drive out and check them out on a calm day when there are a few cool clouds around.

From there I crossed the old down south highway and over to Heron Island, where I saw a heap of Pelicans strutting their stuff on the small island offshore. These creatures are very organised. The island seems to act as an airport and they had their own circuit protocol, just like any airport and there also seemed to be times when they think like a team and arrange to take off together, formate together, explore together and then return to the airport.

A very peaceful drive home it was!

  1. Beautiful and interesting, thanks. What species of Pelican do you see down under? Here in Eastern California I am witness to massive migrations, thousands of birds, of the American White Pelican. Pelicans are obviously a successful clade, with multiple species across multiple continents. Spectacular, really, for a large predator. And, my oh my, when you see them fly…

    1. Good evening Andrew,

      Nice to hear from you! I too love watching the majestic Pelicans and the species we have down here are quite big.

      Without being sure, I think they are called the Great White Pelican….I could watch them for hours!

      Thanks for dropping by and I hope to see you here again!


      True North Mark!
