When the radius is extended further away from the lake and closer to Kenya, lions, ostriches, gazelles, zebras, and buffalo can all be found in these unexpectedly fertile surroundings. Volcanic carbonate ash also creates lush pastures, which are ideal mating grounds for wildebeests during their journey. Predators are kept away from the newborn flamingo chicks that hatch on the lake’s salt islands because of the severe pH levels. Lake Natron, for example, is home to between 65 and 75 percent of the world’s population of lesser flamingos, and the lake’s alkalinity aids in this process. In fact, the lake and its environs are brimming with life: Lake Natron, on the other hand, isn’t a bleak pit of death and sorrow. This volcanic by-product is high in sodium and potassium carbonate, which seeps into the lake and affects the pH. Ol Doinyo Lengai, a nearby volcano and the only active generator of nitro-carbonatite lava, feeds this mineral deposit into the lake. Because of the high levels of sodium carbonate in the lake, the poor critters appeared to have “turned to stone” in the highly caustic waters of Tanzania’s Lake Natron. You may recall the haunting black-and-white photos of calcified birds that went viral a few years ago. Lake Natron -The Bird-Calcifying Lake That’s Actually Teeming With Life. The surrounding bedrock is composed of alkaline, sodium-dominated trachyte lavas that were laid down during the Pleistocene period….Who would have known about these Stange and Unique places around the world? Let’s have a look at some of them.ġ. The alkalinity of the lake can reach a pH of greater than 12. The water is oversaturated with salt, can reach temperatures of 140 degrees and has a pH between 9 and 10.5-so corrosive that it can calcify those remains, strip ink off printed materials and burn the skin and eyes of unadapted animals.ĭoes Natron lake turn animals into stone? How hot is the water that flamingos stand in? The alkali salt crust on the surface of the lake is also often colored red or pink by the salt-loving microorganisms that live there. The red accessory photosynthesizing pigment in the cyanobacteria produces the deep reds of the open water of the lake and the orange colors of the shallow parts of the lake. Scientists disagree on the source of the deadly gas within Lake Nyos. On the night of 21 August 1986, between 1,600 and 1,800 people and countless animals were killed by a large natural release of carbon dioxide gas. The lake responsible for the most deaths without drowning is Lake Nyos in Cameroon, Central Africa. This raises the lake’s alkalinity to far above water’s normal neutral pH of 7. The caustic lake has another strange quality: it appears to turn animals to stone. The lake is within the Lake Natron Basin, a Ramsar Site wetland of international significance.ĭoes natron lake turn animals into stone?īright-red Lake Natron in Tanzania may not look inviting enough to take a dip – and that’s a good thing: its water is extremely alkaline. It is in the Gregory Rift, which is the eastern branch of the East African Rift. Lake Natron is a salt or alkaline lake located in north Ngorongoro District of Arusha Region in Tanzania. Unlike those other lakes, though, Lake Natron is extremely alkaline, due to high amounts of the chemical natron (a mix of sodium carbonate and baking soda) in the water. The ghastly Lake Natron, in northern Tanzania, is a salt lake-meaning that water flows in, but doesn’t flow out, so it can only escape by evaporation. The lake’s hypersaline water can strip away human skin, and breeds algae toxic to many forms of animal life, but the bird flourishes in these conditions thanks to its incredibly adapted body. Visit Lake Natron in Tanzania and you’ll find 75% of the world’s 3.2 million lesser flamingos. Because Lake Natron is brimming with alkaline water, it offers the perfect environment for this bacteria to thrive. Lesser flamingos primarily feed on a cyanobacteria known as spirulina (Arthrospira fusiformis), which grows in bodies of water with high alkalinity levels.
