Science is Fun Fridays!

 The waters of Lake Natron in Tanzania have the ability to mummify animals that die within.

Deposits of sodium carbonate - once used by Egyptians - flow into the lake from surrounding hills.

This includes Ol Doinyo Lengai, which is the world's only active carbonatite volcano.

The magma is rich in alkali elements, and those travel into the waters.  The lake has a pH as high as 10.5

But there is a thriving ecosystem of salt marshes, wetlands, tilapia, and algae.  Lesser flamingos nest here for breeding season.
