Salar de Aguas Calientes IV, Salt flat in Antofagasta Region, Chile
Salar de Aguas Calientes IV is a vast salt flat positioned at 3,676 meters in the high Andes, with white mineral deposits covering its surface. The terrain consists of hardened salt layers interrupted by darker volcanic material that once flowed across the basin.
The site developed from a large ancient lake that gradually transformed into the current salt deposits through evaporation. Volcanic activity from nearby mountains contributed material to the basin, shaping the landscape into what exists today.
Local communities have long regarded the salt flats as part of the vast high-altitude landscape they inhabit and traverse. Researchers working here connect this place to broader understanding of mountain ecosystems and how they function.
Visit during the drier months when road conditions are more stable and weather is more predictable. Prepare for the extreme altitude with proper acclimatization, carry plenty of water, and wear sun protection since the open terrain offers no shade.
The salt surface displays natural geometric patterns and cracks formed by thousands of years of mineral deposition and drying. These formations create a striking puzzle-like appearance across the vast white expanse.
