Lake Natron and Lake Bahi are the only two alkaline lakes in East Africa.
Both lakes are extremely shallow and are fed by smaller rivers and hot springs.
Brandt discovered something amazing during his trip to Lake Natron, and the photographs will take your breath away.
Animals, both on the shore and floating in the water, that look as though they have been turned to stone.
The haunting photos are almost too amazing to believe.
“Discovering [these animals] washed up along the shoreline of Lake Natron, I thought they were extraordinary — every last tiny detail perfectly preserved down to the tip of a bat’s tongue and minute hairs on his face," Brandt said to The Huffington Post.
“The entire fish eagle was the most surprising and revelatory find.”
Brandt photographed the animals in 2010 and 2012.
“No one knows for certain exactly how [these animals] die, but it appears that the extreme reflective nature of the lake’s surface confuses them, causing them to crash into the lake,” Brandt wrote in his photo book.
Brandt goes on to explain the animals' stone-like appearance.
“The soda and salt causes the creatures to calcify, perfectly preserved, as they dry,” he said.
