"Lake Thetis, don't miss it" The Pinnacles Tip by vtveen

On our way back after visiting the Pinnacles to Cervantes we were attracted by a signpost to ‘Lake Thetis’. We took the turn off and through a rather bad gravel road we reached after about 1½ kilometres this shallow lake in a more or less dreadful landscape. Lake Thetis is a very salt lake, which is fed by an underground stream.

On an information board we did read that so called ‘stromatolites’ are living in this lake. These are among the oldest living organism on earth, with samples indicating similarities with fossils from up to 3000 million years ago. The ‘stromatolites’ in Lake Thetis are supposed to be between 2000 and 3000 year old.

Walking along the borders of the lake the ‘stromatolites’ seemed to be rocky molehills. But later we realised, we had seen some rare living organism.

Directions:
Just outside the village of Cervantes is a turn off to Lake Thetis.
