Lake Hillier



Water bodies are marked with blue on the map. But nature likes to mess with us and creates oddities just like Lake Hillier in Australia. 🙂 Well , this magic is quite obvious, isn’t it ?

Pink Lake is located on Middle Island, off the coast of Western Australia. The reason of its unique colour is still a topic that is not fully understood by scientists. The lake is not always pink . The most common speculation is that the distinctive colour of the water changes as a result of green alga Dunaliella salina , halobacterium Halobacteria cutirubrum, and/or high concentration of brine prawn . Once the lake water reaches a salinity level greater than that of sea water, the temperature is high enough and adequate light conditions are provided, the alga begins to accumulate the red pigment beta carotene. The pink halobacterium grow in the salt crust at the bottom of the lake and the colour of the lake is a result of the balance between, D. salina and H. cutirubrum.
