10 Wonderfully Weird Pink Things in Nature (6 of 6)

10. Lake Retba, Senegal

Nicknamed “Lac Rose,” this lake in Senegal is practically a twin to Australia’s pink lakes. The pink color comes from the same Dunaliella algae that adore all that super-salty soup. Depending on sunlight and salinity, the lake can range from pastel pink to intense blood-red. Locals harvest salt from the lake bed, using shea butter to protect their skin from the briny water.
