Such halophile organisms include some cyanobacteria that make their own food with photosynthesis as plants do. As water evaporates during the dry season, salinity levels increase to the point that salt-loving microorganisms begin to thrive. The lake has a deep red color characteristic of those where very high evaporation rates occur. It is said, that the journey alone is worth it for the views. But for those who do choose to visit Natron, they are rewarded with some of the most dramatic scenery they have ever see in Tanzania. The surrounding country is hot and often very dry and dusty – not very conducive to travel. It is quite shallow, less than three meters (10 feet) deep, and varies in width depending on its water level, which changes due to high levels of evaporation, leaving concentrations of salt and other minerals, notably sodium carbonate (natron). The lake is fed by the Southern Ewaso Ng'iro River and also by mineral-rich hot springs. Nestled between rolling volcanic hills and deep craters, Lake Natron sits at the lowest point of the rift valley – 600m above sea level – and is probably the world's most caustic body of water. Lake Natron is a salt lake located in northern Tanzania, close to the Kenyan border, and just north east of the Ngorongoro Crater, in the eastern branch of Africa's immense Great Rift Valley.
