Nick Brandt 2013, Courtesy of Hasted Kraeutler Gallery, NYIn 2011, when he was traveling to shoot photos for a new book on the disappearing wildlife of East Africa, Across the Ravaged Land, photographer Nick Brandt came across a truly astounding place: A natural lake that seemingly turns all sorts of animals into stone.“When I saw those creatures for the first time alongside the lake, I was completely blown away,” says Brandt. “The idea for me, instantly, was to take portraits of them as if they were alive.” A bat Nick Brandt 2013, Courtesy of Hasted Kraeutler Gallery, NYThe ghastly Lake Natron, in northern Tanzania, is a salt lake—meaning that water flows in, but doesn’t flow out, so it can only escape by evaporation. Over time, as water evaporates, it leaves behind high concentrations of salt and other minerals, like at the Dead Sea and Utah’s Great Salt Lake.Unlike those other lakes, though, Lake Natron is extremely alkaline, due to high amounts of the chemical natron (a mix of sodium carbonate and baking soda) in the water. The water’s pH has been measured as high as 10.5—nearly as high as ammonia. “It’s so high that it would strip the ink off my Kodak film boxes within a few seconds,” Brandt says. A swallow Nick Brandt 2013, Courtesy of Hasted Kraeutler Gallery, NYAs you might expect, few creatures live in the harsh waters, which can reach 140 degrees Fahreinheit—they’re home to just a single fish species (Alcolapia latilabris), some algae and a colony of flamingos that feeds on the algae and breeds on the shore.Frequently, though, migrating birds crash into the lake’s surface. Brandt theorizes that the highly-reflective, chemical dense waters act like a glass door, fooling birds into thinking they’re flying through empty space (not long ago, a helicopter pilot tragically fell victim to the same illusion, and his crashed aircraft was rapidly corroded by the lake’s waters). During dry season, Brandt discovered, when the water recedes, the birds’ desiccated, chemically-preserved carcasses wash up along the coastline.“It was amazing. I saw entire flocks of dead birds all washed ashore together, lemming-like,” he says. “You’d literally get, say, a hundred finches washed ashore in a 50-yard stretch.” A songbird Nick Brandt 2013, Courtesy of Hasted Kraeutler Gallery, NYOver the course of about three weeks, Brandt worked with locals to collect some of the most finely-preserved specimens. “They thought I was absolutely insane—some crazy white guy, coming along offering money for people to basically go on a treasure hunt around the lake for dead birds,” he says. “When, one time, someone showed up with an entire, well-preserved fish eagle, it was extraordinary.”Just coming into contact with the water was dangerous. “It’s so caustic, that even if you’ve got the tiniest cut, it’s very painful,” he says. “Nobody would ever swim in this—it’d be complete madness.” A fish eagle Nick Brandt 2013, Courtesy of Hasted Kraeutler Gallery, NYFor the series of photos, titled “The Calcified” and featured in this month’s issue of New Scientist, Brandt posed the carcasses in life-like positions. “But the bodies themselves are exactly the way the birds were found,” he insists. “All I did was position them on the branches, feeding them through their stiff talons.” A dove Nick Brandt 2013, Courtesy of Hasted Kraeutler Gallery, NY
