Thrombolites at Lake Clifton. Thrombolites are a living relic from the earliest days of life, when they produced oxygen that over eons created the atmosphere we live in today. The rock-like structures cover a total of about 4 sq km in the calcium carbonate-rich fresh water of the lake, growing at an average of a millimetre a year. A boardwalk allows viewing without damage to the thrombolites. Yalgorup National Park, Western Australia, Australia
