Lake Hillier's Pink Color Mystery Explained

Lake of Strawberry Shake

A small island off the southern coast of Australia's home to a pristine pink lake — a pool so vibrantly colored that it looks like an ocean of strawberry milkshake. Lake Hillier isn’t a trick of the light or any added dyes turned a lake's water into a neon candy hue. This real-world mystery lake has actually maintained its hue — a vivid bubblegum pink — for over a hundred years. Lake Hillier isn’t the only natural sight on Middle Island, but it is the most fascinating. Separated from the surrounding Southern Ocean by a thin strip of sand and forest, the lake holds an almost otherworldly charm. Despite its concentrated, vivid hue, the lake distinguishes itself from a rose gold dream by being up to 10 times saltier than the ocean.

The Salt Dreamscape

Lake Hillier's deep pink hue is breathtaking, but its real beauty lies in its sheer saltiness. The lake is a unique ecosystem that can turn the saltiest stuff in our oceans all other things into tiny bubbles of nothing. Lake Hillier can withstand this because of its powerful and colorful algae. The lake is so rich and concentrated with salt that part of the lake's surface has begun to crystallize. The microscopic life that thrives in these waters are the reason for the lake's bright bubblegum pink color. Besides surviving in an environment that is thought to be almost as hostile as the outer edge of the solar system, the bacteria survive on a diet of salt. And the salt they consume is something else entirely.

Topography and comparative phenomena

Lake Hillier's border is a thin strip of sand and forest that keeps the Southern Ocean from mixing with the pink water. The water of Lake Hillier is approximately 10 times saltier than the ocean, and it is a vast, open basin of salt that waters this region of Australia. Lake Hillier, unlike other lakes, extends eastward to the ocean and shares a boundary with the Southern Ocean. The lake has held its pink hue for centuries, but in 2022, heavy rain diluted the salt and changed the color to green. If the rain continues, the pink hue could return in 5-10 years, but it may fail to ever return. Sacramento is home to another lake that gained a pink hue to a variety of reasons. Lake Natron has a similar pink hue to Lake Hillier. However, Lake Natron has a red hue due to the presence of red algae and cyanobacteria. Cyanobacteria and algae give Lake Natron its red hue. But the red hue of Lake Natron can change to red or pink depending on the amount of light it receives from the sun. Despite its red hue, Lake Natron is considered the pinkest lake in the world due to its resemblance to pink. The soil and the surrounding vegetation are in stark contrast to the purple hue of Lake Hillier's water. The soil and vegetation around Lake Hillier is composed of a thin strip of sand and forest.

Bacteria Blamed for Lake Hillier's pink

The pink water of Lake Hillier is the result of a bacterium called Salinibacter ruber. The bacterium was discovered in 1989 using microscopy techniques and revealed it made up 20% of the lake's DNA. The bacterium is considered to be a sort of red alga, as it cannot be seen with the naked eye.

When Bacteria's Water Faded

After years of glowing pink, Lake Hillier lost its pink hue to green due to heavy rains. The salt content of the lake decreased due to heavy rains, and the pink hue disappeared. The pink hue may return in 5-10 years, if the salt increases or the bacteria returns, but it may fail to ever return. Unfortunately, the loss of the pink hue of the lake is not only due to the loss of the bacteria. The lake has also lost its salt, which is a consequence of heavy rains. The pink hue of the lake is the result of the salt in the lake, which creates a bubble-like atmosphere and attracts the bacteria that give the lake its pink hue.

The Timid Tourist Guide

The pink hue of the lake may return, but it is uncertain. It is essential to preserve the lake's ecosystem to preserve its pink hue. The salt, which is a by-product of the bacteria, is essential for the lake's pink hue, and the bacteria is essential for the lake's pink hue. The lake is an ecosystem, and the bacteria and the salt are a part of the ecosystem.
