LAKE NATRON: THE LAKE THAT WILL PETRIFY YOU

It is said that there is a lake in Tanzania that petrifies every animal that submerges in its deadly water. Is that true?

If you tape Nick Brandt, Lake Natron in Google, you will be shown an amazing collection of balck-and-white photographs of a decadent grey moor. Probably it willl remind you somehow of a 19th century poem, or even of death. It is grey, dark and quite sinister.The photo is dominated by a prettified animal, probably a bird. Also grey. Spooky, isn’t it? It feels cold: as if a death had arrived there like a deadly breeze.

But if you only type Lake Natron in Google (and you omit the pictures by Brandt) you will see a bright red lake surrounded by yellow hills and a bright blue sky. You will also see flamingos, lots of flamingos. I’m not cheating you. It is just the same lake, the same époque. I will also add that the photos by Brandt are not false, nor retouched. 
Lake Natron is a salt lake located in North Tanzania, In the border with Kenya. It covers between 600 and 100 square kilometers depending on the season It is very near to a volcano: Doinyo Lengai (translated as God’s Mountain). This is a major factor. The volcano releases minerals and compounds to the lake: chlorine, sodium, magnesium and sodium carbonate.They are all very alkaline compounds. This sodium carbonate is very abundant in the lake. Sodium carbonate is a salt that, in reaction with water, creates a very alkaline solution. This salt helps the process of conservation of corpses –in ancient Egypt it was used in the process of mummification. This solution rises the PH of the lake’s water up to 10.5. Taking into account that caustic soda’s PH is 13.5 we can assume that this is an extremely alkaline (and hostile) environment. This alkaline water scalds and ocular damages to undapted animals, but that’s all. No animal is petrified by the lake, although some people argue that it does, especially after watching Brandt’s work. The animals were not killed by the lake, they died accidentally, naturally… And the compounds of the lake petrified (calcified) the corpses.

The environment is extremely alkaline, so Whow can flamingos live in there? Well it also has a scientyfical explanation: The redish color that paints the lake is not a mineral, but organic. An algae called Spirulina (adapted to the alkaline water) releases red pigment that paint the water. this red pigment attract the 2,5 million flamingos that live in the lake. They are well adapted to the environment, and they feed on the Spirulina. As well s they have a great place to brred, safe from predators. To avoid the alkaline water they stand on the mud or salt islets.

The artist also had a trick. He did not find the corpses as they appear in the photos. He found the calcified animals on the shore of the lake but he admitted that he moved the corpses to create an illusion, and I think it was quite effective.

  1. Amazing!!!!
    How did you find this? It is absolutely incredible that a lake of these conditions can exist in the world. Normally every lake or lagoon has its own ecosystem, but this is the exception. And the colour red is amazing. I believe you have said the truth, but when i get bigger i will try to go to see it with my own eyes.
    Sincerly, thank you for the information!

  2. Hahahahaha great chemistry article! It is shown that you study chemistry in our high school. It is really amazing as Nuri has said and the pink colour is great, pink flamingos living in a pink lake eating pink algae. However, I think it is such beautiful that tourists will soon destroy or alter that environment, human kind doesn´t matter abput that, what is really a pitty. The photos are incredible and the landscape with the volcanoe at the background, well I´m astonished.

  3. I agree with Sofía and Nuria, it is incredible how flamingos and Spirulina algae have adapted to this lake instead of trying to find a place more "normal". Moreover, I think the work made by the photographer is awesome. The fact that Nick Brandt looked for the bodies of the animals, placed them so they looked petrified and then took and edit the photos so they were that gorgeous, probably meant many months of hard work.
    After reading this article I would like to say that now I have added Lake Natron to the list of places I would like to visit.

  4. Wow! I am really surprised. This lake is really mysterious. Thanks to investigation it has been proved one more time that everything has an explanation; however it is still extraordinary! Nick Brandt did a very good job, although he invented most of the part. For this reason I think that it is justified that people believed what he said. Sincerely, before seeing the chemical explanation, I also thought that this lake could petrify organic matter.

  5. It's incredible what science an make, isn't it? I want to see it with my own eyes because the effect that the colors make together is perfect. For these reasons are why I like so much photography, sometimes it's better even that the real life.

  6. What an amazing and interesting post!
    It´s really impressive how these corpses can be petrified by the calcium action.
    This environment seem as a movie one, with all the bright colours like pink and animals being petrified.
    Definitely, you have made a great job in the tecnical investigation reserch.

  7. So, in conclusion, the artist cheat us, those animals are not black and they don´t have that position.
    About the lake, it isn´t so strange. In Spain we can visit a lake with similar features in Andalucia.
