Lake Retba (Senegal)


Remember the photo of the potash mining ponds?  Here's a similar process occurring naturally in a lake in Senegal, where high levels of salt support the growth of a halophilic extremophile (Dunaliella salina) which produces a red pigment, turning the salty water pink.

The salt is harvested by local villagers.
