WHY is Lake Natron phenomenal?

A lake covered with a crust of salt can change color throughout the year. Thanks to the halophilic cyanobacteria microorganisms that live in Natron, the water takes on juicy reddish and pinkish hues several times a year. When the temperature rises, the bacteria release a pigment red, staining the lake.

The concentrations of salt and alkali in Lake Natron are so strong that animals and birds that accidentally enter the water are killed and mummified. The exception is the lesser flamingos: these birds have ideal breeding conditions here. High water temperature, reaching 50°C in the wetlands, allows flamingos to incubate their eggs at any time of the year.
