This Alkaline African Lake Turns Animals Into Stone
In 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.” The 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. As 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.” Over 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.” For 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.” http://blogs.smithsonianmag.com/arts...ls-into-stone/ |

The artist had locals collect corpses then he set them up in natural looking shots.

That's not surprising at all; the rift lakes in Africa are where you find all commercially traded cichlids (lakes Malawi, Tanganyika and Victoria; the rift lakes). And yes, cichlids are territorial, aggressive and ultimately sturdy as all hell. Even rift lake cichlids like a higher PH; I try to keep my cichlid tank at about 8.0. The easiest way to do it is to chuck limestone into the tank as decorative rocks, etc... You can also buy buffers designed to keep your PH pretty high. It's hell on pumps and light fixtures. But man - 10.5 is pretty insane.

We want him on the field for opposing teams. It's now in our best interest to keep him healthy and in a starting position.

Their bodies just don't look like they were pulled from a death rattle. Especially the eagle and swan. Not saying it's a hoax or anything, they just don't look dead for lack of a better explanation. |
