A number of expeditions to the lake have led to the finding of various birds, including flamingos, fish and even bats eerily captured post-death. Animals that perish in the water are turned into statues through calcification, preserved by the sodium bicarbonate content. These red waters are also referred to as ‘The Petrifying Lake’ for a very good, though macabre reason. Gathering along the nearby saline lakes to feed on algae, the flamingos then nest on seasonally-forming islands on Lake Natron, protected against predators by the caustic environment.Īmazingly, two endemic species of fish can be found in the slightly less salty water around the edge of the lake, living right on the doorstep of the much less hospitable environment. In fact, it is the only regular breeding ground in East Africa for the lesser flamingos, who depend on this one location. The lake’s high temperature and intense salt content tends to repel most animals, however it is home to some invertebrates and birds. This is often red or pink in colour itself due to the same microorganisms found in the water. It is the cyanobacteria in these organisms that produces the colouration within the lake.ĭue to the high level of evaporation leaving behind certain minerals plus the composition of the surrounding bedrock, Lake Natron has concentrated into a caustic alkaline brine that tends to leave a salt crust on the surface.

This is a characteristic of lakes with a very high evaporation rate, as salinity levels increase to the point where salt-loving microorganisms thrive. The most striking feature of Lake Natron however is the deep red colour of the open water mixed with the often orange hue of the shallower parts.

Despite its vast size, it is only the sixth largest lake in Tanzania. Located in the Arusha Region of Tanzania, sitting below the Ol Doinyo Lengai volcano within the Gregory Rift, Lake Natron is a beautiful yet sinister wonder of nature.įed by the Southern Ewaso Ng’iro River plus a number of mineral-rich hot springs, the entire lake is less than three metres deep and, at its fullest, is approximately 35 miles long by 14 miles wide.
