Photographs of Birds and Bats Calcified in the Waters of a Toxic Lake

Petrified creatures found on the shoreline of Lake Natron in Northern Tanzania are the subject of a fascinating new book of photographs by Nick Brandt, titled "Across the Ravaged Land". The book documents this rare phenomenon caused by the chemical makeup of the lake—an extremely basic alkalinity that preserves these creatures for eternity. According to Brandt: "I unexpectedly found the creatures washed up along the shoreline of the lake. No-one knows for certain exactly how they die, but it appears that the extremely high soda and salt content of the lake causes the creatures to calcify, perfectly preserved, as they dry."
