Kay Cypher, Ancient Earth (LANDSCAPE 2024)

Thrombolites at Lake Clifton south of Perth Western Australia. Love this special colourful land especially, when seen from above. Thrombolites are rare on modern Earth, but exist in areas of groundwater discharge with high concentration of nutrients and organic ions, such as shallow seawater, freshwater, and saltwater lakes, and streams.
