Make animals stone! Red Lake "Lake Natron"
Africa's bright red salt lake "Natron Lake" that shows why flamingos are pink

A little unusual color lake in Tanzania Natron Lake. Although it is a paradise of flamingos, because of the different quality of water, it is in a harsh environment for other creatures to survive. The animals who lost their lives at the lake will be fossilized with their appearance

Lake Natron

"Lake of Flame"
Strong alkaline salt lake in Lorindo Province, Arusha Province in the northern part of Africa / Tanzania Allied Republic.
It is a salt lake located on the east branch of the Great Lift Valley (Great Rift Valley) extending north and south of Africa. In the northeast there is the world's largest size Ngorongoro crater.
The Ewaso-Ngiro river and high-temperature spring water rich in minerals flow into this lake. Water depth is very shallow, less than 3 m. The size of the lake varies with the water level. The water level fluctuates drastically due to an abnormally high water evaporation rate. Concentrated salt and minerals, especially sodium carbonate (natron) are left on the lake shore.

Surrounded by gentle volcanic hilly areas and deep valleys, the Natron Lake, lying in the deepest part of the grove, 600 meters above sea level, is probably the world's highest corrosive lake. This lake, which is also the breeding ground of flamingos, dyes flamingos in a vivid pink color. The size of the lake will vary depending on the amount of rainfall, but it is up to a length of 57 km and a width of 22 km. The water depth is shallow, less than 3 m. From the southern tip of the lake to the east the Galley Mountain, from the southern end to the south is the Ordinyin Rengai. It has a large catchment area of ​​23,207 km 2 in the Central Kenya Highlands, the main incoming rivers are the Ewaso Ng'iro River or Ngare Nyiro River flowing past the border line from the north and the Peninj River flowing in from the northwest from the northwest . Also, hot and soda-rich spring water that blows out from the bottom and surroundings of the lake also feeds the lake water. There are no outlets on the surface and underground, and water loss occurs only by evaporation.

In Tanzania's low altitude semi-arid region, most of rainfall less than 800 mm per year falls between December and May. Temperatures during the day often exceed 40 ° C. Due to this hot and dry environment, the evaporation rate of the lake is high, salinity continues from salty land, so salt concentration of lake water is extremely high. The salt water of Lake Natron contains at least 8% sodium chloride. Because Natron Lake is rich in dissolved sodium carbonate, it touches when touching. Also, it is estimated that the northwest side of the lake is covered by a layer of mixed salt of at least 2,100 km 2 with an average thickness of 1.5 m.

Another name for Lake Natron is "Lake of Flame". When the microorganisms in the water breed greatly it looks like a bright red flame.

Lake Natron shows its distinctive color with its very high evaporation rate.
The red pigment of blue-green algae etc. produces a deep redness spreading all over the lake, dyed the shallow to orange. The solid matter of the alkali salt that precipitates on the surface of the lake is sometimes dyed red or pink by the halophilic microorganisms living in the lake.
As the water evaporates in the dry season, the salinity of the lake rises to the concentration at which halophilic microorganisms begin breeding.

Change color
Lake Natron shows its distinctive color with its very high evaporation rate. When the water in the dry season is low, the salinity concentration of the lake rises, and the halophilic microorganism reaches the level at which breeding begins. The halophilic microorganism contains certain blue-green algae. Cyanobacteria are microscopic organisms that grow in water and acquire their own nutrition through photosynthesis like plants. The red pigment of blue-green algae etc. produces a deep redness spreading all over the lake, dyed the shallow to orange. The solid matter of the alkali salt that precipitates on the surface of the lake is sometimes dyed red or pink by the halophilic microorganisms living in the lake. The crystallized mass of soda grows round and creates a mysterious pattern on the lake surface.

 

"A lake that disappears soon"
Lake Natron is a large lake with a length of 50 km, a width of 20 km, a depth of 3 m. It forms the Magadi - Natron basin with the lake Magadi in the north. During the late Pliocene and Pleistocene, it is thought that a vast lake was formed in this basin several times, and there are numerous dry salt lake layers. It has been estimated that Lake Natron continues to shrink in a dry environment, eventually becoming a salt plain, eventually becoming a grassland after the period of rain around 5, 000-6, 000 years ago.

Flamingo's paradise
Lake Natron is the only one in East Africa, famous as a breeding ground for flamingos of threatened threatened species, and its population is said to be 2.5 million.
Flamingo's body changes to pink color by eating blue-green algae containing pigment.
As the salt concentration rises, the blue-green algae also increases, so flamingos that feed on it can make a lot of nests on this lake.

Spirulina native to this place (blue-green blue-green algae with red pigment canthaxanthin) is a good bait for flamingos. Originally flamingo is a whitish bird, but because it eats with Spirulina as the bait it makes the body pink.

Flamingo nests on a rock made of evaporation residue of the lake. Lake Natron is a safe breeding ground for flamingos because predators targeting the nest are blocked by corrosive lake water.

The color of the flamingo pink is obtained from the red pigment of this blue-green algae, and the color of the flamingo turns white when less food is used.

This is why flamingos are pink
Since Flamingos in the zoo can not eat natural Spirulina, they say that they add picatinis added with β carotene and make them pink.

"The Lake of Death"
Lake Natron is a highly toxic "lake of death" of water, and most living creatures can not live.
The pH of the lake is as high as 9-10, as alkaline as ammonia, trees do not grow near the lake, no shade. For many animals, it is hard to live.

Soda water lake
Lake Natron is not just a salt lake, it is also a lake of soda water squirting sodium carbonate from the bottom of the lake and its surroundings. A round vortex-like mass that stands out in the lake is the one that this soda crystallized. The size of the vortex can reach as much as 20 m.

 

Name of naturally occurring sodium carbonate hydrate. It can be taken from salt lake etc. In ancient Egypt, it was used to dehydrate soap, detergent, or dehydrated milk.

Fossilize animals
In the daytime, the evaporation rate of the lake water exposed to the temperature of 40 degrees Celsius is high, the salt content flowing from the salty land always keeps a high rate, and a harsh environment such as alkalinity high as pH 9 to 10.5 which is comparable to that of ammonia , The dead birds and the bat of the bat will be eternal.

The water here contains a lot of soda and salt, and this soda and salt leads to hardening (calcification) of living things, and it is preserved intact as it dries.

 

There seems to be super and rare species that escape the natural enemies and inhabit in this extreme situation.

This is the only breeding ground of coframingos in order to prevent intrusion of predators trying to threaten breeding grounds because it is a harsh environment.

Flamingo nests on a rock made of evaporation residue of the lake. Lake Natron is a safe breeding ground for flamingos because predators targeting the nest are blocked by corrosive lake water.

Nick Brandt
A nick brandt who recently took pictures of fossilized animals and published a photo album "Across the Ravaged Land". After picking up animals on the lake, we made a pose at the time that we were "alive", so to speak, "raw", so to speak.

 

On the banks of Lake Natron in the northern part of Tanzania, I saw an unexpected sight that all kinds of animals, such as birds, bat, were being launched. There is no one who knows what is dead, a certain place. However, since the surface of the lake is like a mirror, it may have misunderstood the landscape reflected on the surface of the water as genuine. Like a bird striking a glass window. The water here contains a lot of soda and salt, and it is thick enough to soak the ink in a matter of seconds after picking a box of Kodak film. This soda and salt lead to curing (calcification) of living things, and when dried it is preserved intact.

After picking up animals on the lake, we made a pose at the time that we were "alive", so to speak, "raw", so to speak. I resuscitated the soul and caught life in death.

Impact on human's natural environment
At present, fresh water flowing into Lake Natron increases and the balance of salt concentration is threatened. The cause is due to the planning of the forest clearing in the basin and the plan of the hydroelectric power plant. Among these development plans include the construction of embankments to stop fresh water at the northern end of the lake, but the threat of salt dilution at habitat is still serious.
As a new threat to Lake Natron there is a soda ash plant whose development is being studied on the lake shore [5]. In this facility we pump water from the lake, extract sodium carbonate and make powder detergents for export. In addition to this, more than 1,000 workers will live and coal-fired power plants will be set up for factories as well. Furthermore, there is a possibility that the developer will introduce hybrid shrimp to increase production capacity.

Chris Meijin, the African representative of the Royal Bird Protection Association of the UK said, "The possibility that rare flamingos will continue breeding even in the face of such a crisis is nearly zero, I will abandon the flamingo which is on the verge of extinction at the end ". Today, groups of 20 environmental groups are conducting activities to stop this development program globally.

Old human beings
From the Lake Sandstone Formation of Peninj, just west of Lake Natron, nearly complete mandibles of the Human family were discovered on January 11, 1964 by a team of Richard Lekey et al. The lower jaw with this crowned teeth was a mandibular fossil of the Boysay species that was discovered for the first time since it was also from the male of Australopithecus boisei (classified as Paranthropus boysay Paranthropus boisei) [7]. It is estimated that the age is about 150 ± 100,000 years (early Pleistocene) by the K - Ar dating method of the basalt lava flow immediately above. "Peninj's lower jaw" is currently in Kenya National Museum in Nairobi.
Peninj is one of the production areas where the oldest Ashuran stone tools are found.
