The Fascinating Stromatolites
Lake Thetis has some of the most impressive stromatolites on the planet. Stromatolites are rock-like structures formed by stromatolite-building micro-organisms that secrete minerals over time. These organisms, including primitive-celled organisms, have been around for billions of years, they are one of the oldest forms of life on Earth. Today the lake’s stromatolite community is still thriving, a living fossil.
These microbial communities have been important in understanding the history of stromatolites and their role in oxygenating the early atmosphere. The lake water is saline, perfect for these ancient life forms to thrive. As you walk along the viewing platforms you’ll see thousands of rocks rising out of the lake, each one a testament to life’s persistence in harsh, saline environments.
A Photographic Paradise
For photographers Lake Thetis is a dreamland. The still water reflects the surrounding landscape and the stromatolites are a dramatic subject. The lake shores are stunning, especially at sunrise and sunset when the light brings out the colours of the lake and its ancient inhabitants.
