Just off the South-West coast of Australia, nestled on the banks of Middle island in the Recherche Archipelago, stands Lake Hillier - perhaps the world’s most striking lake. Notable for its vibrant bubble-gum pink color, this lake must be seen to be believed.
Standing at around 600 meters in length and 250m in width, the lake is small enough to walk around - yet it is not the easiest to get to. Tourists can get a clear view of it from above via a flight tour or access it from the sea by boat if accompanied by an official guide.
Why Pink?
The reason for the lakes pink color has never been definitively proven, but scientists believe it is likely to be the result of the presence of the organism Dunaliella salina. These red algae are unusually tolerant of very high salt concentrations, meaning they are able to exist and photosynthesis in conditions that other micro-organisms could not. During photosynthesis, they produce carotenoid pigment similar to those found in carrots, which produce a red dye. Other bacteria in the lake may also play a part and it is likely a consequence of various natural phenomena reacting together with the salt that ultimately gives rise to this wacky color. The color remains the same all year round but appears less vivid up close as it does by plane. Nevertheless, even when bottled and taken home, the water retains its distinct color.
In recent years, the Extreme Microbiome Project has been conducted by the Association of Biomolecular Resource Facilities (ABRF) and Metagenomics Research Group (MGRG) to properly analyse the microgenomic qualities of the organisms in the lake. They discovered Dunaliella salina, Dechloromonas Aromatica and various other interesting species.
Some History
The lake was first discovered on 15 January 1802 by Matthew Flinders, an explorer and cartographer. He took samples of the lake water and his first sighting is recorded in his journal, describing it as 'a small lake of a rose color'. It was Flinders who named it Lake Hillier, after a fellow crew member William Hillier, who had died of dysentery. Nearly a hundred years later, the lake was mined for salt, but this industrial enterprise was cut short due to the salt's toxicity
Despite the salt's toxicity, the lake is technically safe to swim in, although a special license is required from the Western Australia Department of Environment Conservation. Few other animals could comfortably live in such conditions, so swimmers can safely swim without fear of encountering one of Australia's many deadly creatures! Just make sure not to drink the water...
Is this lake unique?
Surprisingly, this is not the only pink lake in the world. Lake Retba in Senegal is also a vibrant bubble-gum color and has been successfully harvested for salt by locals. Laguna Colorada in Bolivia has a stunning pink color, framed by the silhouette of the Andes Mountains in the distance. If that wasn't enough pink, the lake is also a popular hangout spot for endangered James' flamingos! There are even other pink lakes in Australia, such as Hutt Lagoon on the Coral Coast, Lake Eyre and Lake Bumbunga.
