The main attraction close to the Natron is Ol Doinyo Lengai, the Maasai ‘Mountain of God’, a textbook volcano that rises more than 2km above the surrounding Rift Valley floor to an altitude of 2,960m. Natron also attracts up to 100,000 migrant waders during the European winter. There is some large wildlife in the area, but Natron’s main faunal claim to fame is as the only known breeding ground for East Africa’s 2.5 million lesser flamingos, which congregate at an inaccessible part of the lake between August and October.

Almost 60km long but nowhere more than a metre deep, this primordial alkaline sump is renowned for its caustic and unusually viscous waters, which are enclosed by a crust of volcanic ash and salt, as well as a few isolated swamp patches fed by bubbling hot springs. “You’d literally get, say, a hundred finches washed ashore in a 50-yard stretch.Set within the Rift Valley on the eastern border of the Ngorongoro Conservation Area, Natron is perhaps the most starkly beautiful of all the Rift Valley lakes south of Turkana. I saw entire flocks of dead birds all washed ashore together, lemming-like,” he says.

During dry season, Brandt discovered, when the water recedes, the birds’ desiccated, chemically-preserved carcasses wash up along the coastline. 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).
