One of the most mysterious places in the world is the Lake Natron (02025‘S 36000‘E), located along the branch of the Rift Valley, known also as Gregory Rift, in the northern Tanzania.
The lake is characterized by a wide stretches of water, which will highlight in red during the seasonal flowering of algae. In fact, it is the red photosynthesizing pigment in the cyanobacteria responsible for the deep reds of the open water of the lake and the orange colors of the shallow parts of the lake.
The erosion of the surrounding volcanic rocks has enriched the waters of the rivers with large quantities of dissolved salts, which, transported into the lakes, have crystallized due to the high evaporation caused by the strong insulation. In the dry season, the reverberation of the white and irregular salt surface becomes blinding. After the rains, a thin layer of water remains, which splits the salt into floating crust or `trona’.
These features can be seen in the underlying detailed satellite image of Lake Natron.
Only the flamingos can survive in this arid vesicular environment moving barely in alkaline water searching for the abundant algae that make up their nourishment.
