A lake full of Pepto Bismal? Australia’s Lake Hillier – a bubble-gum pink wonder that scientists have yet to unravel
From above, Lake Hillier, located on the edge of Recherche Archipelago’s largest island in Australia, looks to be filled with Pepto Bismal. It’s bubble-gum pink waters are so unusual, airlines report passengers getting up from their seats and crowding around windows to get a peek of the stunningly beautiful natural wonder. Scientists are unsure why its waters retain their rose pink color but believe it may be from a dye created by the organisms living in the lake – Dunaliella salina and Halobacteria. Another theory proposes that the pink color might be attributed to the presence of red halophilic bacteria in the salt crusts. What they do know is that the bright pink waters are no illusion. The water retains its pink hue when taken away in containers.
