The world is full of strange and weird natural-beauties, holding thousands of wondrous places, and the amazing bright pink lake of Australia, known as the Lake Hillier, is undoubtedly one of them.
This unmistakable pinkish-beauty is located in the Middle Island of Western Australia, which spans about 600 metres wide. And we may have found various online stuff claiming it to be an unexplained and mysterious lake for its strange appearance.
The answer is simply – No, there’s no such mystery behind the strange pinkish appearance of the Lake Hillier.
Then, the stereotypical question apparently comes in our mind that why this lake is pink in colour?
Well, the pretty cool answer is diving into the water of this lake. Actually, pink lakes are the natural phenomena that draw visitors from far and wide, providing livelihoods to local people, and these natural marvels tend to have a striking colour due to the presence of reddish algae. Yes, it’s the colour of those algae that inextricably inhabit the lake’s water body.
Study and research on the microbes found in this pink lake:
Researchers who had collected various microbes from this pink lake for test-sampling found that most of the microbes were reddish algae named Dunaliella salina, which is long thought to be the main culprit behind the pink water of the Lake Hillier. Especially found in sea salt fields, these halophile green micro-algae produce pigment compounds called carotenoids, helping it to absorb sunlight. These compounds are the actual reason behind the pinkish beauty of the Lake Hillier, giving the algae-bodies a reddish-pink colour.
Though Dunaliella salina is the radical contributor to Lake Hillier’s unique pigmentation, the researchers found some other red-coloured microbes including a few species of archaea, along with a type of bacteria called Salinibacter ruber that all together provide a pure reddish appearance to this lake.
Other places that also have very similar phenomena in some of their lakes:
There are some other countries from around the world including Senegal, Canada, Spain, Australia and Azerbaijan, where these strange pink lakes could be found.
In Senegal, Lake Retba, in the Cap-Vert peninsula of the country, has such a high concentration of salt (about 40%), that causes it the pinkish look. That lake is harvested by the locals who collect salt using long shovels to pile boats high with the mineral, and to protect their skin from the water they rub their skin with Shea butter.
Canada’s Dusty Rose Lake, in British Columbia is pink due to the particulate in the glacial meltwaters feeding it. The surrounding rock is purple/pink in colour; the water feeding the lake is said to have a lavender hue.
In south-west Spain, another two large salt-water lagoons with the pink-water phenomena sit adjacent to the city of Torrevieja. The “Salinas de Torrevieja,” means “Salt Pans of Torrevieja,” which turns pink-purple when sunlight falls on the algae-rich waters. The strange colour of the Torrevieja Lake is caused by pigments of the Halobacterium bacteria which live in extremely salty environments. This is also found in the Dead Sea and the Great Salt Lake.
