Lakes are transparent-bluish coloured, but did you know that there exists a lake which is a bubblegum - pink in colour? Lake Hillier, also known as the Pink Lake, is a strange lake located on Australia’s Middle Island, which is the largest island in the Recherche Archipelago and is 11 kilometres from the coast of Cape Arid National Park. It has a strange pink colour, which makes it different from all the other lakes in the world. It is a saltwater lake, about 600 metres wide; is surrounded by a strip of sand and a densely vegetated area consisting mostly of eucalyptus trees. This lake is separated from the dark blue ocean by just a thin strip of land covered by Melaluca, which is a plant found in Australia. This lake was founded in 1802 by an English Navigator, Matthew Flinders. Due to its pink colour, this place is a tourist attraction.
The colour of this lake is still a mystery to this date. Some scientists believe that it is the work of some seaweed rich in carotenoids called Dunaliella Salina, which belongs to a special species called Dunaliella. When the lake water reaches a high level of salinity, the high temperatures and sunlight make the algae release a kind of pigment that colours the lake. It is also believed that the presence of some microorganisms and bacteria that live and grow on the surface of the lake may give it the pale pink colour.
Our Mother Earth has given us many mysteries to unravel, and with each, we understand our plant Earth more. These mysteries may be the key to understanding other mysteries, so we shall protect and conserve our environment just like the Recherche Archipelago Nature Reserve has been protecting and maintaining this area since 2012.
