Science is Totally Awesome!
7 Australia’s Lake Hillier
Is this otherworldly lake man-made? No, and it’s not where Pepto-Bismol comes from! Scientists believe its bright pink bubble-gum color is due to mother-nature.
One theory is its color comes from a combination of low nutrient concentrations and the bacteria, “Dunaliella salina and Halobacterium”. Another suspect is the “red halophilic bacteria” that thrive in the lake’s salt deposits.
Although Lake Hillier looks “toxic”, an Australian Environmentalist group noted it does not have “adverse effects upon humans”. Also mentioned is that the lake when seen from the shore appears translucent pink, not opaque as when viewed from above. Unfortunately, it’s prohibited to walk on Middle Island in Western Australia where the lake is located, therefore it can only be seen from the sky.
