Australia’s massive Lake Hillier mysteriously glowing PINK due to algae

[Australia] Lake Hillier is on the largest island in Western Australia’s Recherche Archipelagohas and since it was discovered in 1802 scientists have been baffled about its neon hue.

Would you bathe in Lake Hillier? These people have decided to take a dip in the wacky waters

But recent tests have shown the salt lake turns pink thanks to a combination of algae and microbes.

In dryer months the salt reflects the sunlight and the pool appears to turn white.

Shane Smith, who lives three hours away, said it was “stunning”.

The 42-year-old, who works in a cheese plant, said: “I visited the lake for the first time recently and thought it was just stunning.

“I didn’t go in the water but quite a few people were.”

A new theory explains why the lake goes pink could solve the mystery explains the reason behind the unique colour on its website, suggesting it is still somewhat of a mystery.

“Still a topic that is not fully understood by scientists, although most suspect it has to do with the presence of the Dunaliella salina microalgae,’ they reported.

“The Dunaliella produces carotenoids, a pigment found in carrots as well.

“But the presence of halophilic bacteria in the salt crusts could be another explanation.

“A reaction between the salt and the sodium bicarbonate that is found in the water may cause it as well.”

Unlike the natural occurring Lake Hillier, this pink lake in Stavropol city in Siberia is the result of a chemical spill

In October a lake turned pink in Russia – but this was because of a chemical spill.
