Lake Clifton Thrombolites

National Parks and Reserves

Lake Clifton in the Yalgorup National Park, south of Mandurah is well known for its special rock-like formations that provide a unique look at what life was like at the dawn of time. They are the largest Thrombolite reef in the southern hemisphere.

These amazing formations are called thrombolites, and like the famous stromatolites at Shark Bay, they are built by micro-organisms too small for the human eye to see.

It’s one of the few places in the state where living thrombolites survive.

These peculiar structures live on the eastern edge of Lake Clifton and are most easily seen in March and April.

There’s an observation walkway that allows you to get up close to the thrombolites.

Microbial mounds, which are the remains of thrombolites, can be seen at nearby Lake Preston.

Yalgorup National Park is about half an hour’s drive south of Mandurah.
