The lake alkalinity can reach a pH level of more than 12. Water containing high concentrations of salt minerals such as sodium and trona remains in the lake as freshwater evaporates. The lake temperatures frequently exceed 40 degrees Celsius. The region experiences erratic seasonal rainfall, primarily between December and May. The lake is 57 kilometers long and 22 kilometers wide. Lake Natron is quite shallow, measuring less than three meters deep and varying in width depending on the water level. The lake is located at the base of mount Ol Doinyo Lengai, an active volcano. It is situated in the Gregory Rift, the eastern branch of the East African Rift. Like other soda lakes, Lake Natron has high levels of various salts, and it is very high in alkalinity. Let’s hope his images are not a portent of what’s to become of this spectacular place.Lake Natron is located in north Ngorongoro district of Arusha region in Tanzania. From the look of Brandt’s pictures, the place is already dead. The spectacle the Lesser Flamingo puts on at Lake Natron may soon disappear. The human activity may directly drive off the skittish birds, not to mention the ways both projects might alter the ecology of the water and mud the flamingos have come to rely upon. A dam and a soda ash extraction factory will dramatically alter the ecology of the lake. Lake Natron is such an attractive mating site for flamingos because the water stays low enough to prevent nest flooding but remains high enough that there’s a barrier between predators and the conical nests the birds build. That mating ground is now under threat from industry. For the Lesser Flamingo, Lake Natron is a singular, prime breeding site. In some ways, Brandt’s photos mask the importance of Lake Natron to life in and around the body of water. Those that fall in and perish are exceptionally preserved by the salts that make the lake so unique, but the lake’s surface isn’t an aquatic equivalent of the Medusa’s gaze. And for those animals that do become interred here, animals don’t immediately die and turn to stone upon touching the lake. Lake Natron is a hotspot for beautiful life. BBC natural history unit programs and even a Disney documentary have featured the flamingos who congregate in this picturesque place. The importance of Lake Natron to the Lesser Flamingo isn’t a secret. Lake Natron is also an essential breeding ground for the Lesser Flamingo. Even though the lake is particularly warm and salty, Koerth-Baker notes, algae within the lake supports a species of tilapia adapted to the unusual conditions. ![]() And, just like the Great Salt Lake, Lake Natron is hardly lifeless.īoingBoing’s Maggie Koerth-Baker has already covered the peculiar fish that live in the alkaline waters of the strange lake. Dead pelicans, seagulls, and other birds take on a similar appearance as salt covers their bodies along the margins of the Great Salt Lake near my home. The flamingos and bats didn’t really become petrified in place, as if calcified by ominous clouds of salt-filled smog. ![]() But as Brandt himself has noted, the images are more art than science, and these pictures obscure the resiliency of life in and around the lake.Īs Brandt told New Scientist and other news sources, he collected the dead animals and posed them on their dark perches. The gloomy images make the lake look like a living museum where animals fall into the water and immediately turn to stone. ![]() ![]() If you’re a natural history fan and have been online at all this week, chances are you’ve seen photographer Nick Brandt’s stunning photos of mummified birds and bats along the shores of Tanzania’s Lake Natron.
