"To the Nyungars (Aboriginal people) of this region, Lake Clifton is a very special place. It is significant in culture and history, with stories passed from generation to generation. It is a place for yoka (women) and it tells the creation of the lake and thrombolites by the Waugal ( a mythological serpent that helped shape the land). "
"The thrombolites of Lake Clifton represent some of the earliest forms of life on earth, living, breathing rock-like structures more than 2000 years old. The thrombolites reef at Lake Clifton is the longest in the southern hemisphere 15km in length and widens to almost 120 m in parts. Thrombolites known as “Living Rocks” are microbial formations that have a clotted internal structure. They grow less than 1 mm a year. Thrombolites are rock-like and built by micro-organisms. When these microbes photosynthesize, they precipitate calcium carbonate (limestone), which creates the dome shaped thrombolites. Three hundred fifty million years ago thrombolites were the only known form of life on Earth. Microbes found in thrombolite formations are believed to be responsible for the first oxygen production which allowed life to exist on earth. The thrombolites of Lake Clifton are thought to be more than 2000 years old. "
In December 2009 the thrombolites were listed as critically endangered under the Commonwealth Environmental Protection and Biodiversity Conservation Act 1999 .
