From the Department of Awesome Natural Wonders comes the Lake Hillier, the mysteriously bright pink lake found on Middle Island in Western Australia that looks like it’s made of Strawberry Nestle Quik or Pepto-Bismol. No one knows for sure why the lake sports such an unusual colour.
According to Wikipedia: The reason for the lake’s colour is still under investigation. A possible explanation according to some scientists involves the low nutrient concentrations and different types of bacteria and algae. The pink colouration could also be from a sea salt and nahcolite (sodium bicarbonate) deposit reaction or red halophilic bacteria in the salt crusts.
