Description
The Salar de Uyuni is the world’s largest salt flat — 10,582 square kilometres of near-perfectly level crystalline salt crust at 3,656 metres altitude in the Bolivian Altiplano. During the January–March wet season, rainfall accumulates on the flat surface in a thin layer — typically 20–30cm deep — that transforms the entire flat into a near- perfect mirror. With no horizon visible to differentiate sky from reflection, the image appears to show the sky twice — above and below — with the horizon completely dissolved. This photograph was made at the precise moment when a dramatic altocumulus cloud formation was centred over the flat, creating a symmetrical composition around a horizon that is barely detectable. The only visible differentiation between reality and reflection is in the colour saturation — the reflected image carries a marginally deeper blue due to the thin water layer’s absorption characteristics.
