Lake Hillier: The Pink Lake in Australia
Lake Hillier is a pink-coloured lake on Middle Island in Western Australia. Middle island is the largest of the islands and islets that make up the Recherche Archipelago, a group of about 105 islands and over 1,200 ‘obstacles to shipping’.
The tiny lake only spans about 600 meters wide but its rose pink colour in unmistakable. However, the reason why it’s pink remains a mystery.
The reason for the lake’s colour is still under investigation. A possible explanation according to some scientists involves the low nutrient concentrations and different types of bacteria and algae. The pink colouration could also be from a sea salt and nahcolite (sodium bicarbonate) deposit reaction or red halophilic bacteria in the salt crusts
