Theme: Otherworldly White Deserts and Salt Pans
These brilliant white expanses look almost lunar, yet each formed through very different geology. The Danakil Depression's sulfur-crusted salt flats sit below sea level in one of Earth's hottest places, while Chott el Djerid's cracked salt crust shifts color with the Saharan sun. The Rann of Kutch floods into a vast salt marsh each monsoon, and the Bonneville Salt Flats host land-speed trials on their mirror-flat crust. Salar de Uyuni, the largest of them all, turns into the world's biggest natural mirror after rain.
