Hillier : The Pink lake in Australia

Lake Hillier is situated in the Middle island of Australia. The length of the lake is six hundred meters. The island and lake are thought to have been first charted by the Flinders expedition in 1802.
The most notable feature about this lake is its flamboyant water color, rose pink. It is such a significant distinguishing feature of the archipelago that air passengers often take note of it. This pink color is natural and the color would not change or alter when the water is taken in a container.  Scientist can not prove why the lake color is pink. But they assume that excessive salt, varieties moss and paperbark and eucalyptus trees may be the cause of pink colored water.
