Lake Clifton is about an hour's drive from Perth, Western Australia. It is host to a 'colony' of thrombolites or living rocks. These are Earth's most ancient life forms, dating back to the Archaean eon, well they are the result of them anyway. Millions of microbes secrete calcium carbonate (limestone) which forms the domes which stretch for 15km along the shores of the lake. The earliest fossils date back 3.5 billion years but these particular ones are around 2000 years old.
This was shot during a full moon which bathed the foreground in ambient light. You can see clouds beginning to move in from the west, forming whispy streaks on the right side of the photo.
