Shifting horizons. Sossusvlei sand dunes, Namib desert, Namibia

Picture a sea of shifting sand dunes glowing orange in the sunrise, stretching as far as the eye can see. Welcome to the Namib desert, spanning thousands of miles across Namibia. Estimated to be 55 million years old, it is believed to be the oldest desert in the world. It also boasts some of the tallest sand dunes on Earth, including the famous 'Big Daddy,' which towers roughly 325 metres; Dune 7, the highest dune in Namibia at 383 metres; and Dune 45, which, at roughly 170 metres, is a favourite among photographers.

At the heart of this vast, arid expanse is Sossusvlei, seen in today's image. A salt and clay pan surrounded by towering dunes, Sossusvlei tells a story of contrasts. Every 10 years or so, an extraordinary event occurs when the Tsauchab River floods the pan, transforming it into a stunning turquoise lake. Nearby is the eerie Dead Vlei, with its ancient, desiccated camelthorn trees, which remain frozen in time as the extremely dry climate keeps them from decaying. Visitors to this landscape also witness an ecosystem full of surprising life. From the adaptable gemsboks to the ingenious Namib desert beetle that drinks fog droplets that collect on its back, the Namib is brimming with stories of survival and resilience.
