Introduction: What Is Lake Natron?
Located in the remote northern region of Tanzania, near the Kenyan border, Lake Natron is one of the most alien and hauntingly beautiful landscapes on Earth. Known for its blood-red waters and ability to calcify animals, this alkaline lake is not only a geological marvel but also a vital ecological habitat.
Why Is Lake Natron Red?
The intense red and orange hues of Lake Natron are caused by halophilic (salt-loving) microorganisms and cyanobacteria that thrive in its alkaline waters. As the water evaporates, salt concentrations increase, and these microbes produce red pigments that give the lake its iconic coloring.
Does Lake Natron Really Turn Animals to Stone?
A popular myth says animals that touch the lake turn to stone. While dramatic photos by Nick Brandt show petrified birds and bats, the reality is less magical but still fascinating. The lake’s extreme alkaline pH (up to 10.5) and high temperatures (up to 60°C or 140°F) can cause rapid calcification of animal remains, preserving them eerily well—but it doesn’t instantly “turn” animals to stone.
Flamingos: Thriving in a Hostile World
Despite its harsh conditions, Lake Natron is the only regular breeding site for the 2.5 million lesser flamingos in East Africa. These birds feed on the very microorganisms that give the lake its color. The hostile environment also keeps predators away, making it a perfect nesting site.
