9 Most Magical Natural Phenomena at Salar de Uyuni

5. Salt Polygons and Bubbling Springs

Underneath Salar de Uyuni's surface is a sophisticated network of mineral-rich water channels and subterranean springs forming distinctive geological structures. Large polygonal patterns unique from the usual hexagonal surface construction are produced by these subsurface water motions. Sometimes the pressure from subsurface springs produces tiny geysers and bubbling pools that breach the salt crust and pour mineral-rich water to the surface. Maintaining the environment of the salt flat depends critically on these springs, which also help to produce fresh salt crystals continuously.

Unique extremophile bacteria found in these subterranean water systems have been identified by scientists as having adapted to the high mineral concentrations and salinity. Every visit to the salt flat is different since the interaction of the surface and the subsurface water system generates dynamic patterns that evolve with time. These geological processes also help to create islands and salt mounds dotting the otherwise level terrain.
